Cable Overmolding — All You Need to Know

Cable Overmolding

Overmolding is now the most evolved form of wiring available. The Over-molding cable add aesthetic value to the cables which the medical industry requires. While many haven’t thought of over-molded cables before, today, they are becoming more and more popular. Do you want to know the reason? Then please come with me.

Cable Overmolding

Chapter 1: What is Over-molding?

Over-molding is a new technology in the market. It makes wires have more longevity and reliability even in the harshest regions of the world. In this process, we combine the wire and the connector using two or more materials to make a single device.

It is a combination of the wire and the connector seamlessly combined. To do this, first, the cable assembly is put in a mold. You then cover the substrate – or the first material – with molten plastic substance.

You inject the material using two techniques-

Insert Molding or single shot

Multiple shots or two shot

So now you may think about why you should go for over-molded cables at all in the first place?

The answer is that these cables have more lifespan and you can rely on them for durability as well as safety purposes. It increases the cable exit flexibility for better connections. Also, it offers better shock resistance of enormous scale. Additionally, it creates water resistant cables-all for your benefit!

In the next chapter, you will know more about which material to use for the over-molded cables.

Chapter 2: Over-molding Cable Material Selection

The first thing you need to know is that the major factor which choosing the material for your over-molded cables is Thermal Bonding. Thermal Bonding is the lock and key that holds the over-molding material to the single set of cable and connector. If the compatibility between your cable jacket and molding material gets skewed, then the entire assembly will not be a success. But do not fret! We are here to help you with just that. Just go through the table below for all the information you need to make an informed choice.

Common Overmold materials:




Polyvinyl Chloride (PVC)

The next chapter will help you understand how to complete over-molding.

Chapter 3: The Process of Over-molding

What is the process?

To satisfy your curiosity, let’s discuss it in brief and simple terms.

The process is simple and convenient. Here the cable and the connectors join together to form a single unit that is very easy to use. The process takes help of bonding to make the unit. Here, a layer of plastic material, which is durable in origin, covers the original substrate through bonding. You can use materials according to your needs by following the informative chart above.

Over-molding achieves the best possible compatibility between the cable, the connector, and the over-molding material.

The two main techniques are injection molding and insert molding.

Injection molding:

It is an interesting and rather convenient process. The substrate is put in the mold and then molten plastic through injection shoots into creating one single solid unit. It is quite versatile and highly flexible and is several industries use this technique.

Machine cutting mold

Insert Molding:

When two parts connect, then we use insert molding. It is a permanent encasing of cable and connector. You normally see it in the cases of threaded inserts and electrical appliance encasing.

machine mold insertion

3.1: The process of Injection Molding:

The process is as follows:

We put the substrate in a mold.

We heat thermoplastic material.

We use high pressure to push the molten material through a nozzle into the mold.
Hydraulic pressure makes the material stay in its place.

Once we cool it, the single unit drops out soldered and perfect!

3.2: The process of Insert Molding:

The process is as follows:

We put the substrate in a mold.

We heat thermoplastic material.

The filling surrounds and fills up around the insert.

The completed product is a single unit.

The next chapter will introduce you to the application of these over-molded cables you are learning.

Chapter 4: The Applications of Over-molded Cables

The high usefulness of over-molded cables makes them very efficient and durable and in sync with the latest technology.

The applications of over-molded cables are as follows:

1. Military Market Applications:

 Military components now use over-molding for longevity and more effectiveness and durability. So, you can upgrade these instead of replacing them.

2. Medical Market Applications: 

You use these in surgical instruments for better gripping. Plus, it’s been seen that the instruments can withstand autoclaving and acidic and basic harsh cleansers.

3. Consumer electronics: 

You find these everywhere including in laptop chargers, or cords for the television. If you need durability, convenience, and grip, you need these cables.

Television Cables

4. Solar energy:

 They are heat resistant, and you can easily use them in transmitting solar energy through cables.

5. Industrial/OEM:

 Medical OEMs use injection molding to get the best results. It reduces cost, is patient friendly, and you can use them to create custom designs.
Let’s learn next about the benefits you get when you use over-molded cables.

Chapter 5: Benefits of Over-molded Cables:

So why use over-molded cables over the simple ones for your cable assembly? What is so different about them that makes them special and much better?

The following are the benefits of over-molded cables:

Boot IP rating: Gets increased

Provides the product design freedom: We see that these are easier to work with as they are flexible and not brittle. So, we can easily mold them to form malleable cables. As they have flexible exits, the movement is easier.

Improves the aesthetic appeal of cabling: These are easier to dye. You can find several colors. These are useful in the medical industry for aesthetics and helps in improving the doctor-staff-patient relationship.

Over-molded Cable

Simplifies installation and Decreases human error: There is only one single unit of cable and connector bonded together using thermoplastic material. So, it is easier to install, and you reduce the human error to a minimum.

Enhanced the Durability: Over-molded wires offer durability or longevity so that the wires do not get abrasions. You don’t have to worry about safety issues in the long run, even in the harshest of environments.

Increasing product quality and durability: The product quality is better than individually using the cables and connectors. Plus, these cables have more lifespan. You can rely on them for durability and safety. Increase the cable exit flexibility for better connections, get shocked resistance of enormous scale, and create water-resistant cables-all for your benefit!

You will learn about the difference between over-molding and two shot molding next.

Chapter 6: Over-molding VS Two Shot Molding

There is a slight difference between the two. You are now going to learn about the difference between these two and which one you will need.

Over-molding is a new technology in the market. It makes wires have more longevity and reliability even in the harshest regions of the world.

The process is simple and convenient. Here the cable and the connectors join together to form a single unit that is very easy to use. The process takes help of bonding to make the unit where a layer of plastic material which is durable in origin covers the original substrate through bonding. You can use materials according to your needs by following the informative chart above.

The main success of Over-molding lies in achieving the best possible compatibility between the cable, the connector, and the over-molding material.

Two shot molding:

This process is the best for bulk orders, and factories use this process for large production volume of more than 10,000 parts. Usually, the products that have colors and materials and components of multiple nature use this process.
The process is simple. It is the same as injection molding.

The process is as follows:

We put the substrate in a mold.

We heat thermoplastic material.

We use high pressure to push the molten material through a nozzle into the mold.
The difference lies in the fact that it involves more than one nozzle — the process changes by injecting a single mold with multiple materials – in only one molding cycle.

There is a steel layer that creates space for one material after you inject another.

Where Over-molding costs you fewer labor charges, multiple molding has more. However, the unit cost is much lower, and the enhanced designs have greater reliability than in over-molding. In over-molding, essential and individual parts get more attention.

So which is better? The multi-cavity or the single cavity molding?

Let’s learn about this now.

Chapter 7: Multi Cavity VS Single Cavity

The difference is as follows:




This mold is useful in large scale productions, generally in industries.

This mold is for a single small production

Cost is greater in the beginning, but each over-molded part costs less

2. The cost of each over-molded part is more than in the case of multi-cavity.

Requires less machine time

3.Requires more machine time

2-20 cavities present

4. Generally, eight cavities are present



A multi-cavity molding factory

The Advantages and Disadvantages:

The main advantages of multi-cavity molding are that it is very efficient and cost effective for bulk production in factories. It makes the production of individual over-molded parts easier and cheaper. The disadvantage is that in case the product needed is not in bulk, for that the setup cost up front is very high. If one mold breaks, you have to change the entire machine, which signifies the serious loss of money.

For the per piece over-molded part, the single-cavity is much better.


Using over-molded cables reduces the costs of making a product. You can use it efficiently and with durability. You should work with teams that make the task easier, less time consuming, and lets you create unique and new designs.

USB Cable – Everything You Need To Know

USB cable

Why do you think the USB cable is essential? USB cables are probably one of the simplest yet complex sets of cables. These cables differ according to their uses. They appear in various sizes and are used to transfer data, information, and signal from different a host and another device.

USB cables are compatible with various devices. To get the best satisfaction from the USB cable, you must have a deeper understanding of its structure. Are you ready?

USB cable

Chapter One:What Is USB?

USB is an acronym for Universal Serial Bus. It is an interface that encourages ease of communication between devices and a host. USB connects various devices such as digital cameras, scanners, printers, and so many more. They are used for electrical supports and have replaced interfaces such as parallel and serial port. It is specially designed to aid easy installation, quicken transfer rate, and hot swapping.


The USB cable has various features that make it unique. Some of these features are:

Hot swapping

This is a unique feature of the USB cable, where a device can be removed/replace without disturbing the system. It makes sure that the system is not interrupted by booting. Hot swapping can control the operating mechanism despite an unforeseen hardware abnormality. In as much as this true, it is also important to pay attention to certain areas when hot swapping certain devices such as a camera. A little mistake in hot swapping can ruin the port of the device.

The use of Direct current: 

This is a unique feature of the USB cable that enables it to receive direct current without necessarily transferring data. In this way, it is easier to transit current just by connecting the USB cable to the desired device.

An image of a USB cable icon

Chapter Two:Types Of USB Cable

There are a variety of USB cables. These cables perform different functions and can use in different ways. Hence, it is pertinent to understand these cables and their compatibilities. They are:


It is commonly referred to as USB standard A connector. It is one of the safest USB cables around and also very common as widely used. Its use is also second none and is generally considered a must-have. The cable comes in both flat and rectangular shapes. It is also used on host controller in computers. The USB Type A socket provides a downstream connection for host controllers on computers but also sometimes used as an upstream connection in the peripheral device.


These cables typically use to connect peripheral devices such as scanners, printers, and flash drives.USB Type A male use to make the connection between two USB A style female port. However, you should not encourage the connection of two hosts or computers or computers to a hub using the same A-A cable.

USB Type B: Also known as the USB standard B connector. This USB type is compatible with USB peripherals such as a printer or upstream port or hub. It has a rounded square shape.  This USB has lost its grounds as it has become the least favored because of the presence of other sophisticated types.


It connects to the USB peripheral device peripherals or more.  It forestalls the risk associated with connecting two host computers.

Mini B:

Just like the name presupposes, it is a smaller type of USB cable. It has five pins, which includes an extra ID pin to support USB On-The-Go (OTG). This extra USB pin allows mobile devices and some peripherals to act as the USB host. However, this USB type has a substitute in the form of the micro USB. The advent of well-designed and portable phones has made the micro USB no longer relevant as it was before.


You can find the Mini B USB cable on your digital camera and MP3 player. Its socket design is suitable for small peripherals.

Micro B:

 It is a USB cable type that is designed to maintain the ability to connect computers and other hubs irrespective of the size of the mobile device. Just like the Mini B cable, the Micro B cable also has five pins to support USB On-The-Go (OTG). 


This cable works just like the computer system. It connects to all kinds of portable devices. It enables mobile devices to access external drives, digital cameras, Bluetooth headphones, and other peripherals. To make this feasible, it needs to be compatible with other devices using the right wiring connection in the cable assembly.

Lightning cables

Lightning cables are not exactly cables in the real sense of the word but can act as a substitute for cables.  This cable is reversible just like USB Type C.


This cable is essential for charging iPhones, Personal computers, and iPads. For this purpose, connect it to the USB A type cable.


This is the most recent USB interface. Unlike the USB Type A and USB Type B, the USB Type C is suitable on different devices that have USB ports. Modern electronic devices such as laptops and cellphones make use of this cable type. It is quite confusing, and its usage varies according to devices.


This cable is compatible with different devices. Lots of manufacturers have come to adopt it in producing technological innovations. Manufacturers of Apple phones and Samsung use the USB Type C cable. It enables ease of transfer of data at a considerable speed level. This cable type supports the use of high-resolution displays such as HDMI and Display Port.

Chapter Three:USB Speed Standards

The speed level of the various USB type varies according to its structure and feature. The various standard of speed are:

USB 1.x

Another name for USB 1.x Full speed USB. It can operate at a different speed; Such as Low Bandwidth or Full Bandwidth. Launched USB 1.0 in 1996, but in August 1998 released USB1.1.

How is it now?

It is no longer as popular as it was in the ’90s because its speed was considered rather too slow

USB 2.x

It is known as Hi-speed USB. It is an external device that supports the structure of USB1.1 together with the same cables and connectors.

How is it now?

It supports faster speed than the USB 1.x and also supports the introduction of new ports. Asides that the speed of USB 2.x allows two separate devices to communicate without obstruction. A typical example is a use of an adapter on a computer keyboard and a mobile phone. The adapter can use to charge the phone properly without experiencing any difficulty whatsoever.

USB 3.x

It is the fastest of all the USB cable. Any USB cable termed USB 3.x is the fastest of all cable type. It launched in 2008 and provided more speed than USB1.x and USB2.x put together.

How is it now?

USB3.2 is the latest model of USB 3.x.It encompasses all the features of older versions and is extremely fast. The USB 3.2 comes in three different forms; USB 3.2 Gen 1, USB 3.2 Gen 2, and USB 3.2 Gen 2X2. The newest form of USB is the USB 3.2 Gen 2X2. One notable feature of the USB 3.2 is its super speed. The USB 3.2 product uses the type C connector. To ensure compatibility between these and older cables, an external connector, such as an external hard drive, must be used.

Chapter Four:Some Advice When Using Custom Cable

It is always fun to use USB cables for very reasons and to suit the needed plans. Nevertheless, it is also helpful to understand the basic makeup of these cables and how to handle them to prevent mishap or disaster.

The wire size:

 The wire size is an important factor to consider when choosing a cable. It is because the size of the wire determines the amount of current that can pass through the wire. If the wire is too small for the capacity of current that passes through it, it could damage the wire.

The length:

 The length of the cable ensures that the current functions properly. If the length of the wire is not large enough or if it is more than needed, the resistance is higher and this, therefore, results into fewer watts in your battery bank or grid.

The type of connector: 

The user of the cable should determine the type of connector to use. The connected device determines the type of connector used. The user can decide to either favor connector A, connector B, connector C or to decide between a male or female port/connector.

With or without shielding:

 When you select a USB cable, to determine the cable shield is also essential. It is always important to shield the cable to prevent the hazard from the environment. If the USB is masked and the current is strong, it can cause damage to insulation as a result of leakage of current.

Image of a twisted pair of cable symbol foil shielded

The packaging: 

The packaging of cables is a topic that is considered irrelevant. Ironically, it is one of the most crucial factors in choosing a cable. The packaging should be such that makes the cable water resistant and easy to handle. Failure to package the cable properly can result into increase in cost or worse still damage the cable itself.

Chapter Five:More About USB Cable

There are so much more about USB cables. They are:

USB extension cable: 

This cable can is extendable. It can be extended to cover a reasonable distance between devices.


It can be connected to flash drives

Printer cable:

 If you are using a tech gadget, you probably have a lot of small cables inside it to make it work – wires that connect the circuit board. While round cables were once the choice for some, experts saw a common problem with them. For instance, round cables meant that the wires would wind up over each other. Instead, they saw that choosing flat cables will lead to easy management. Plus, flat cables are lighter in weight and offers more flexibility, something you are looking for today to make electronic gadgets portable, and making them weigh as less as possible.

A flexible flat cable or FFC is an electrical cable that is both flat and flexible. 

FFC is a miniaturized form of the ribbon cable that is flat and flexible as well. You use the term FFC, however, to refer to the extremely thin flat cable. This arefound in everyday gadgets we use, including our laptops, tablets, and even our smartphone.

Think of your iPhone. Did you know that a flat cable is what joins your iPhone screen to the circuit board? If the flat cable breaks, your iPhone will stop working. In any device that you are looking for increased mechanical flexibility, you need an FFC. Unlike round cables, FFC’s put less stress in the components, ensuring you have less worry about any breakage.


 the use of FFC will also differ according to the device. For instance, automotive use shielded FFC because they need high-density mounting and fine lead pitch, along with other factors like high heat resistance. You do not have these properties for FFC’s that you use in other consumer electronic products.

Interestingly, the FFC technology was made by Cicoil Corporation back in 1956, and since then, it has been a popular cable we use in many of our electronic gadgets.

FFC workshop


After the discovery, these cables were immediately used to replace stiff, round, and bulky cables in the computer industry. Today, their use has become tenfold. Today, you use them in most electronic devices like computers, printers, and so on for their simple, efficient structure and low cost due to standardization.

Now, we will talk about the specifications of FFC, which is essential for better utilization of the cable.

FFC working


Chapter 2:FFC of Specification

The specifications of FFC are of 5 types. It is highly important for you to understand more about these specifications so that you can select the most efficient of FFCs for better use.

2.1: Pitch

Pitch refers to the distance between the center of one conductor to the center of the neighboring conductor. You can better understand it as the space between the conductors in the FFC. This space varies according to the type of FFC used. There are various pitches available like 0.500 mm,0.625 mm, 0.635mm, 0.800 mm, 1.00 mm, 1.25 mm, 1.27 mm, 2.00 mm, 2.54 mm.

You can choose the FFC pitch according to your use. Do note though that many providers only supply pitch types from 0.5 mm to 1 mm, as they are the most popular. If you are looking for something else, you might want to ensure that your provider has got the pitch you need.

Flexible FFC

2.2: Types

You have two different types of FFC cables. Since you use FFC connectors for mating cable and the circuitry inside the device in wire to board devices, knowing which one you need can help you.

You will find two types of FFCs available:

1.The Type 1, or Type A- These FFCs have the contacts on the same side at each end.

2.The Type 2, or Type D – You can see the contacts naked on both opposite sides of the cable for these particular types of FFC. You will see that when the cable is kept on the table or a flat surface, one end will have face-up contacts and the other end will have face-down contacts.

FFC Types of cables

2.3: Exposure Length

You will be able to understand the exposure length of the electrical conductor easily. Determine the length of the electrical conductor exposed at the end of the cable.

2.4: Conductors Size

You fill to understand the size of the conductors by the measurement of the width and the thickness of the FFCs.

2.5: Stiffener

You will see that most FFCs have this extra material attached on the opposite side of the exposed length of the cable. It helps ZIF (Zero Insertion Force in IC circuits) or LIF (Low Insertion Force) connections.

FFC Motherboard working

The next chapter will tell you all about the difference between the FFC and the FPC, which will tell you why FFC is a better product.

Chapter 3:FFC VS FPS

What is the FPC cable?

FPC refers to Flexible Printed Circuit. There are two parts to talk about here. One, it has a thin insulating polymer film having conducive circuit patterns fixed to it. Then, there is a thin polymer coating attached to it to protect the conductor circuits.

It is one of the most important interconnection technologies used extensively in recent times.


 The production system of FFC and FPC is completely different. FPC was found to be more vulnerable than FFC.

FFC Printer circuit

In the next section, you will learn about the advantages of using FFCs.

Chapter 4: Why Flat Flexible Cable solution is the best?

FFCs are tiny, flexible, and can be freely bent and folded that will help to reduce the space needed in electronic devices and reduce design costs. They have high rest resistance (110 degree Celsius) and low connection resistance (20 m or less). They are thick and therefore not fragile enough to break.

You can blend, wind or fold FFCs as you want, according to the spatial structures of appliances. It can move in any 3D space and can stretch. That makes FFCs be able to integrate the wire connections and the device components.

FFCs also have the added advantage of being cables with the property that allows good heat dissipation and weldability. It is also easy to use because it can be very easy to install. The overall cost is not that high. Plus, the combination of the softness and hardness is the formula that makes the cable flexible, giving it its well-deserved name.

Optic cable connector

However, do note that connecting flat flex cables can be more difficult than it seems. If you want to go over the process, here is a good video that explains it. 

Flat Flexible Cable solution advantage over IDC/IDT or discrete wire types.

If you are looking for wires for your board connections, there are several choices. So, why will you want to go for the FFCs over the IDC/IDT or discrete wire types?

FFC gives you a one-piece solution to all your difficulties regarding purchasing wires. It does not have separate male and female connectors. So, it saves you both the labor cost for assembly and makes using and storing easier.

FFCs weigh less and do not take up much space. You can use FFC’s for any of your board-to-board interconnect requirements.


 FFCs are usually ZIF; they immediately lock into place. There is no further force exerted on the contacts of the cable because of the connectors. In appliances with high shock and vibration, actuators are put in place to hold the cable together.

The devices where mechanical movement is a must is much better off with the flat flexible cables. There are several reasons for this. For one, the moving part needs the stability of the flat cable. Appliances like scanners or photocopiers have moving arms which are more suited to FFCs.


Did you know that you can bend FFCs several times without breaking? Yes, they will not snap like other round wires that may snap once the pressure input on the crimped areas. The movement of these crimps in housing might also cause severe danger and hazards.

So, did you think about how you can read your texts even when you are outside, and the sunlight is reflecting off your smartphone screen? Have you thought how the touchscreens work by the touch of your fingers?

We will take a look at all that you need to know, and many other things that you might find useful for your everyday life.

Display Cable Assembly

Chapter 1: LVDS Cable

The display cable brings what is happening inside the CPU to the display. Although you primarily use it for video display, you can use it for audio as well. Why do you need to learn about display cable assembly? The answer to this question is easy: in the modern day, technology is an essential part of our lives. It isn’t complicated at all! The LVDS cable is the Low- voltage differential signalling or TIA/EIA-644 cable that gives details of a differential, serial communications protocol. It can operate at low power and can is cheaper to use at extremely high speeds with the help of the special twisted-pair copper wires. LVDS cables have a unique system of functioning. The circuit operation has the current flowing in a loop back to the driver. The differential pair creates field coupling, which results in lower radiated emissions or EMI. The cable transmits waves by creating a difference in voltages between the pair of wires. What’s more? LVDS cables reduce any electromagnetic noise as long as the coupling between the two wires is steady. Display Cable Assembly Whether it be a laptop or a smartphone, all have display cables. This video, for instance, talks about how you can replace the screens on a laptop.


LVDS cables are in use in a variety of different electronic appliances in the present world. The notebook computers use LVDS cables to transmit video data from the graphics processing units to the display with flat panels arranged side by side. These cables are also in use in flat panel displays for television sets and in HDMI cables to transfer files. In the next chapter, you will get to know about the EDP cable.display cable

Chapter 2: EDP Cable

First, you will get to

know about the EDP cable in as simple terms as possible.

What is the EDP Cable?

Transferring files has never been easier!

EDP cables are the Embedded DisplayPort cables that are now in the market and are fast becoming very popular as a choice for connecting driver boards to TFT displays. There are small packets calle

d micro-packets that these cables use to embed the clock signal in the stream of data. We use them to transmit both video and audio, but it

does not work with HDMI ports. Instead, it uses technologies like Ethernet, USB and PCI express. The cable uses a small physical connector. We make

EDP cables from micro-coax cable, and the assembly is simple that has fewer connections. The cables are also useful in controlling power, data and control signals through one single assembly. EDP cables generally use only five signal wires as compa

Capacitive Touch Cable

Chapter 3: Capacitive Touch Cable

You will get your first

introduction to the capacitive touch cable in simple words.

What is the Capacitive Touch Cable?

Remember how the keypad changed to touchscreen? Have you ever wondered how the touchscreen works?

TFT displays are becoming common in all households, and thus, everyone now has the desire to interact with appliances through the mode of touch. If a display requires a touchscreen functionality, then these cables can be in use to connect the display to the PCB. These cables are usually small in size, and they make use of very fine pitch connectors to make the space used less and retain their small form factor.

used in laptops


The major function of the Capacitive Touch Cable is in the touchscreens of televisions, mobile phones, notebooks and so on. There are two types of Capacitive Touchscreens, namely surface and projective. The first one uses corner sensors, and the second one uses a grid of rows and columns that have separate chips for sensing the touch, thereby creating a revolution through touch.

The next chapter will tell you about the cables that let you see even when the sun’s glare falls on your phone screen- the Backlight cable.

Chapter 4: Backlight Cable

Let’s know more about cables by getting an insight into Backlight Cables.

What is the Backlight Cable?

These are the display cables that are important because they increase sunlight readability. LED backlights are the best way to counter glare on the screen. In some cases, separate cables are needed to provide power to the LED arrays. They have fine pitch connectors of around 1.25 mm usually and since LEDs need low power requirements the wire Gauge in also smaller of around 26 AWG.


Have you ever wondered what lets you see that message that popped on your screen while you were outside in the sunshine and the sunlight was reflecting off your phone’s LED screen?

You are about to find that out.

The Backlight Cables are in use all over because they give power to the LED arrays that in turn reduce glare and let us see the screen even with the most amount of sunlight falling on it.

In the next chapter, you will get information about the FFCs and how you can utilise them.

Chapter 5: FFC

What is FFC?

If you use gadgets, you probably have a lot of small cables inside it to make it work –wires that connect the circuit board and make your gadget work. While round cables were once the most popular choice, experts saw a common problem with them. For example, round cables meant that the wires would wind up over each other and also get crimped. Instead, they saw that choosing flat cables will lead to easy installation as well as management. Moreover, flat cables are lighter in weight and offer more flexibility, something you are looking for today to make electronic gadgets portable, and making them weigh as less as possible.

A flexible flat cable or FFC is thin, flat and most importantly, flexible. It doesn’t break away, and you have it everywhere, including your iPhone and other electronic devices like laptops, and tablets.

It is interesting to note that the Cicoil Corporation developed it in 1956, and since then, the flat and flexible cable has been popular all over the world for its ease and utility.

You will find two types of FFCs available:

1. The Type 1, or Type A- If you see the contacts on the same side on each end, you are looking at Type 1.

2. The Type 2, or Type D – If you see the exposed contacts on both the sides of the cable, you are looking at Type 2.

You will see that most FFCs have some material on both the sides of the exposed length of the cable. The material helps facilitate life (Low Insertion Force) connections and ZIF (Zero Insertion Force in IC circuits).

Flat Flexible Cable has other advantages over IDC/IDT or discrete wire types as well.
FFC is what you need to look for if you need one wire that does it all. Since it does not have separate male and female connectors, you can use them to connect to the circuit board easily, saving you labour cost for assembly, and making things easier for you. In short, FFCs take up less space, are more flexible and even in appliances that have high shock and vibration, actuators, can hold the cable together.

While many devices use FFCs, you would find them more in gadgets and devices that need mechanical flexibility, like scanners and photocopiers.

In this article, we will help you find out all you need to know about DB connectors. By the end of this guide, you will become a pro on DB connectors and become able to make informed decisions.


DB Connectors

Chapter 1: DB Connector

What is D-Sub Connector?

DB or D-sub connector is one form of electrical connectors. Their goal is to establish a connection between two points to facilitate the transfer of information or power. The standard was developed by Cannon in 1952 and became popular consequently.

The connectors get their name from the D-shaped metal shield around the pins. At the time of introduction, DB connectors were the smallest of the lot. They can act as multi-way connectors, and you can find the best-known application perhaps in the RS-232 serial links.

D-sub connectors are in use for a long time for serial links in computers. You can still find variations of the DB connector in many computers used today.

DB connectors have two or more rows of parallel connections. The male plug contains the rows of pins, whereas the female plug comes with rows of holes. The number of pins generally denotes the connectors. For example, DB 25 connector has 25 pins, and DB 9 has nine pins.

Here’s a video of how to connect DB connector-

We will talk about the applications of DB connectors in the next chapter.


Chapter 2: The Applications of DB Connectors

DB connectors are used widely for various electronic devices. The connectors are common for establishing communication between various devices such as printers and monitors. They are also applicable for video and gaming controllers. Here are some specific uses of DB connectors-

Electronic Office Systems

DB connectors were one time the standard for office electronics like computers and peripherals. You can connect mice, keyboard, monitors, video outputs, and similar devices to computers using DB connectors. 

Another common application of DB connectors was for connecting printers to computers. For example, DB 25 connectors were useful in establishing connections with the parallel and serial ports.

Medical Equipment

DB connectors are ideal for medical equipment that require precision and performance. DB connectors used in medical electronics have to be reliable along with complying with electrical and mechanical requirements.

Some medical equipment relying on DB connectors include computer tomography system, imaging machines, nurse call systems, MRI machines, and more. You can also use them for various screening, therapeutic, and sensor-based diagnostic systems.

Data Communications

DB connectors are used to facilitate data communication between various devices. The most common application was for RS-232-based serial communications, like exchanging data between the computer and the printer.

DB connectors are also used for connecting modems to allow data transfer between PC and modem. Some computer networks and token ring networks also rely on DB connectors.

In the next chapter, we will discuss the different types of DB connectors.


Chapter 3: Types of DB Connectors

You can find different types of DB connectors to suit various applications. There are DB 9, DB 15, DB 25, DB 37, and DB 50 connectors that come in standard density. On the other hand, DB 15, DB 26, DB 44, DB 62, and DB 78 connectors are of high density.

The density refers to the spacing between the pins of a DB connector. Normal density DB connectors have a pin spacing of 2.76 mm while high-density connectors come with a spacing of 2.3 mm between the pins. You can also find standard density DB connectors.

We are going to explore the different types of standard-density DB connectors in our post.

1. DB 9 Connector

DB 9 or DE 9 connectors were commonly used for serial ports or COM1 ports of older computers. The connectors feature a total of 9 pins arranged in two rows. The upper row of the male end contains five pins while the lower row has four pins. The female connector comes with nine holes and connects to ports of devices.

DB9 connectors were widely used when serial ports were standard on computers. The connectors work with the EIA/TIA 232 serial interface standard. DB 9 connectors were common for peripheral devices such as a mouse, keyboard, and joystick. You can also find them on DB 9 cable assemblies used for data connectivity.

Current configurations such as USB, PS/2, and FireWire have replaced the DB 9 standard. Still, you can use BD 9 connectors for applications based on serial communication. Token ring adapters also make use of DB connectors.

DB 9 connectors offer the smallest footprint among all DB connectors.

2. DB 15 Connector

DB 15 is a part of the D-sub miniature group of connectors and used in computers and communication devices. DB 15 connectors include both the DA 15 and DE 15 connectors.

DA 15 connectors have a larger enclosure, and the pins arranged in two rows. The upper row features eight pins while the lower row comes with seven pins. DA 15 is a male connector and connects to female ports of a device.

DE 15 connectors are smaller compared to DA 15 connectors and have three rows of pins, with five pins in each row. Don’t confuse DE 15 connectors with HD 15 connectors, which also has three rows of pins.

DB 15 connectors were used for game ports of a computer, sound cards, and older AUI network cards. Legacy Mac monitors also used DB 15 connectors, but they have been phased out. DB 15 connectors are also known as Game Port for their use in video game controllers and joysticks.

Another common use of DB 15 connectors was for VGA connections. You can find them on Windows computers and laptops, older CRT monitors and projectors.

3. DB 25 Connector

DB 25 is an analog 25-pin plug version of the DB connector family.  You see the pins in two rows of 13 pins (top row) and 12 pins (lower row). You can also find female DB 25 connectors featuring holes in place of pins.

DB 25 was mainly used to parallel port connections. Some common applications include the RS-232 serial and SCSI applications for computers. DB 25 connectors are also known as IEEE-1284 Type A Connectors if you use them for parallel applications.

In older systems, you will also be able to find female DB 25 parallel ports. Sometimes, the DB 25 male port can also replace the DB 9 port. Older Apple computers used the DB 25 connector for SCSI devices and other expansion cards.

DB 25 connectors are also known as Printer ports as they were previously used to connect printers. Serial connections that depend on the transmission of data through the RS-232 standard also takes help of DB 25 connectors. DB 25 allows asynchronous transmission of data for serial connections using the RS-232 standard.

Text – Using a DB 50 connector

Now you know about the different type of DB connectors and their applications. Next, we move on to the differences between connector, plug, and jack in the following chapter.


Chapter 4: The Difference between Connector, Plug, and Jack

Many people often get confused when you ask them about connectors, plugs, or jacks. The three of them are different components and are not the same. To give you a clear idea, we are going to discuss the differences between connector, plug, and jack.

What is a Plug?

The term plug denotes the part of a cable or wire that you connect to a port. The plug is the connecting part, and you connect it to either a port or a jack.

The most common example of a plug is the power plug.  It has a plug at the end of a cable which you can connect to a power source, mostly wall outlets. You can find male plugs on computer power cords that you can hook into the wall socket. The female plug end goes into the device like CPU, printer, or monitors.

DB Connectors

Text – Using a printer power cable plug

What is Jack?

A jack is the slot or holes on devices where you insert the plug or cards in case of computers. For example, one of the most common types of the jack is the audio jack you find in laptops and computers. 

The jack allows compatible plugs and cables to connect to the hole or jack. Other examples of jack include sound in or sound out jacks, line in and line out jacks, microphone jacks and so on.

What is a Connector?

A connector is also a plug or jack with unique features that connect to a port. Edges of various cards like graphics card used in computers are also called connectors. You can insert the connectors of computer cards into the slots on the motherboard.

Connectors are also found in cables and refer to the end that connects to a port of a device. For instance, USB printer cables have serial or parallel connectors that connect to the printer.

You can easily distinguish between connector, jack, and plug through physical means like visual observation. Their application can also be used to differentiate between the components.



DB connectors are still widely used in many electronics and devices. If you have a DB connector project in mind, we can help you!

Printer Cable – All You Need To Know

Printer Cable

Have you ever given a second thought to your printer cable? Printer cable may seem trivial, but they perform an essential function. Without printer cables, you will never be able to print your documents.

Do you know there are different types of printer cables?

You might not be aware, but there are many things to know about printer cables. So we have prepared this in-depth article to increase your knowledge on the topic. After reading, you will become an expert on printer cables and able to choose the right cable for your needs.

So, let’s begin our tutorial. 

Printer Cable

Chapter 1: Printer Cables

What is a Printer Cable?

Most of us know how to take print outs using a printer. If you have used a printer, you must connect it to your computer via a cable. The printer cable is the cable that connects the printer to your computer. The cable comes with a connector on both ends and transfers printing commands from the computer to the printer.

One end of the printer cable connects to the port on a computer. The other end fits into the port in your printer, setting up a connection between the two devices.

When you give the print command on your computer, the cable sends the information to the printer. Without a cable, your printer wouldn’t function or be able to print documents.

The printer cable facilitates two-way data transfer. It sends the print instructions to the printer and transmits messages or information from printer to computer. For example, the cable sends information related to ink levels, paper status, and printer details to the computer.

You can find different types of printer cables in the market. They vary in size, dimensions, and connection protocols.

Printer Cable
text – printer cable machine use

In the next chapter, we will discuss all different types of printer cables.

Chapter 2: Types of Printer Cables

Printers have a long history of evolution, just like most computer peripherals. The earliest dot matrix printers used parallel cables while all new printers use USB cables. Let’s take a look at some of the printer cables in use-

1. USB Printer Cables

The USB standard has become the most common technology to hook up devices, including the printer. If your printer was manufactured any time in the last decade, there are high chances that it uses a USB connection.

The USB AB cable is the most widely used by present-day printers. The cables feature a USB-A plug at one end that fits into the standard female USB port on your computer. The USB-A end is flat and rectangular and can be recognized easily.

The other end comes with a USB-B plug and has a small, square shape. You need to connect this end to the USB port of your printer.

You will be able to find different types of USB printer cables in the market. Some of the common types include USB Type A, USB Type B, B5 pin, Mini B4, and Micro USB A-B. Printers use specific types of USB cables, so you need to make sure you are using the right type.

USB printer cables are capable of transferring data at high speeds of 480 Mbps. You can ideally use them for bigger projects and bulk printing.

One disadvantage of USB cables is that they are mostly available up to lengths of 16 feet. If the cables are any longer, the data transfer speed begins to drop as the distance increases.

Here’s a video of how to connect a USB cable printer cable to your computer-


2. Parallel Printer Cables

Parallel cables are one of the oldest types of printer cables used to connect dot matrix printers. Before the introduction of USB technology, people commonly used parallel cables. The cables come with flat, wide ends with a series of pins on the male connector. The male connector needs to plug into the female parallel port on the back of the dot matrix printer.

The parallel ports were introduced by IBM to connect their PCs with Centronics printers. Gradually other printer manufacturers also adopted the standard. Parallel printer cables can only transmit 50 to 100 kilobytes of data per second in a serial manner (unlike in a single row in case of serial cables).

The female connector of the parallel printer cable goes into the parallel port on computers. But today, it is not possible to find computers with a parallel port. So if you are using an old printer, you might face difficulties in establishing a connection.

In that case, you can go for an adapter cable. The adapter cable features a parallel connector on one end and a USB-A connector on the other. You have to connect the USB end to your computer and the parallel connector to the male end of the parallel printer cable.

3. Serial Printer Cables

A serial printer cable connects your printer to your computer and transfers information based on the serial communication protocol. The early models of Mac computers used serial ports, but now the technology has been phased out by Apple. You will mostly find serial ports on computers manufactured before the year 2000.

Serial printer cables transfer data using bit-by-bit or serial port communication technologies. The printer cable features 9 to 25 pins at the male end. Serial cables are classified based on their standards and interfaces. The most common type of serial printer cables is the RS-232.

Serial printer cables can handle data speeds of 110 to 19,200 bits per second and are slower than USB or parallel cables. The cables use only two wires to transmit information each way and send data one bit at a time. They are quite cheap due to their simple nature and can connect the printer and computer over longer distances.

The computer and the printer need to have the same settings for a serial cable to work. If the devices have different settings, then the interface will be out of sync.

New Mac computers don’t have a serial port. So if you want to connect a printer that uses serial cables, you need to buy a serial to USB adapter cable.

4. FireWire

FireWire cables use the Apple IEEE 1394 standard to secure high-speed communications and real-time data transfer. The standard developed by Apple during the 1980s and 1990s is used in printer cables to connect them to a computer.

FireWire cables support the plug-and-play feature like USB cables but can only accommodate 63 devices. The cables come with a data transfer speed of up to 400 Mbps using the High-Performance Serial Bus technology.

FireWire printer cables are thin serial cables and more convenient than parallel cables where space is restricted. FireWire cables enable peer-to-peer connection and can connect two devices without the need for an intermediary computer.

FireWire ports still exist on some devices and desktops. They can also carry power along with data and suitable for distances of up to 15 feet.

You can compare the IEEE 1394 interface to USB because the latter can introduce FireWire and use In a short time.

Electrical connector — Everything You Need to Know


We usually never give electrical connector a second thought. They sit at the end of the product, and we mostly ignore their importance.

Electronic equipment will not work without electrical connectors! You have to count in several factors while choosing a connector- what will be the cost factor? Where will be the connectors used? What should be the spacing and pin count?


Surely, there’s a lot of things to process. To help you out, we are going to take an in-depth look at electrical connectors in this article. By the end of the guide, you will know all you need to make an informed decision and choose the best product. 


Chapter 1: What is a Connector

Electrical connectors allow you to join various components of an electrical circuit like wires and cables. The connectors create a continuous path for the electrical current to flow through the connection or circuit.

Connectors can come with male-end plugs or female-end jacks. You can join them together to form a temporary or permanent connection based on your needs.

Electrical connectors facilitate manufacture, assembly and installation of electrical devices by cutting down labor, time and effort. Electrical connectors are widely used in electronic devices, domestic appliances, telecommunication, industrial machinery, computers, and automobiles.

Here’s a video of how connector blocks work-

Basic Composition

Electrical connectors consist of mainly two parts- the housing and terminal.


The housing is the case which contains the terminals. Housing stabilizes the connection and keeps the electrical contacts safe from environmental hazards and short-circuits.

Generally, manufacturers use molded plastic for the housing, but you can also use other insulating materials like ceramics.


Terminals refer to the pins on the connector that establish the electrical connection. Terminals are mostly made of metals, but you can also use other conductive materials like silicon or carbon.

Features of Connectors

You will need connectors with different features for some specific applications. Here are a few important features-

Keyed Connector:

Keyed connectors can only be connected when they are in the proper orientation. The design helps you connect in the right direction preventing damage to the pins.

Lock Connector:

Locked connectors come with a locking mechanism to hold the connectors in place. They prevent the connectors from dislodging or breaking away accidentally during movements or vibrations.

Sealed Connector:

Sealed connectors are used for applications that need to withstand water and water pressure. They can be used underwater up to certain depths.

Waterproof Connector:

As the name implies, the connectors are resistant to water splashed or dampness. But you can’t use them under water.

Moisture-Proof/Oil-Proof Connector:

The connectors are designed to protect the connections from oil or moisture damage.

Filter Connector:

Filter connectors protect the electrical connection from interfering electrical signals like electromagnetic interference (EMI) or radio frequency interference (RFI).

Shield Connector:

Shielded connectors protect the wiring and components from electrostatic discharge.



Now we will take a look at the different types of connectors. 

Chapter 2: Types of Connectors

Electrical connectors come in all sizes and shapes. You can divide individual connectors into various types based on levels, application, and nature of terminals.

Connector Level

Electrical connectors can be classified into one or more categories, known as levels in the professional realm. The levels were put forward by various companies with the guidance of the National Electrical Distributors Association (NEDA). The levels include-

● Wire-to-board or subassembly-to-subassembly level

● Box-to-box or input/output level

● IC chip or chip-to-package level

● IC package or package-to-board level

● PC board-to-board level

Main Connector Types

Let’s discuss some of the main types of connectors based on use.

Board mounted connectors take help of pins to establish a connection between boards. You can also use them to connect USB or audio wires to the board.

4. Board to Board Connectors

Board to Board connectors are ideal for connecting printed circuit boards or PCBs. Each terminal of the connector links with separate PCBs to create a continuous connection. 

The biggest advantage of the board to board connectors is that you don’t need to use wires. The connectors are generally made of plastic and have metal pins or connectors.

5. Circular Connectors

Circular connectors come with multi-pin connectors and applicable for external interfacing. The connectors are useful for transferring data, the transmission of electrical signals and relaying power to devices.

Circular connectors are also called power and control connector as they can carry mixed signals. In industrial applications, the housing is either made of plastic or metal and fulfill the needs of a reliable and secure connection.

6. Coaxial Connectors

Coaxial connectors or coax are used to transmit radio frequency (RF) signals for CATV applications. The connectors have an insulated conductive inner wire covered in a shielding conductor. On top of that, you can find another insulating or protective layer.

Coaxial connectors are designed to carry a huge amount of information. They are also common connectors used in most home video installations.

7. DIN Connectors

DIN connectors follow the standards created by the DeutschesInstitutfürNormung (DIN), a German organization for establishing national standards. DIN connectors are commonly used in various applications like network, microphone, audio, video, data, and telephone.

DIN connectors can be both male and female and can carry high-frequency signals through multiple pins. Computers also use DIN connectors to connect microprocessors and RAM.

8. DB Connectors

DB connectors are officially known as D-subminiature connectors and used in data, computer and audio/video applications. The name comes from the “D” shape of the connector which houses two rows of pins. You can find DB connectors like DB9 and DB25 in serial and parallel port connections in PCs.

DB connectors may also have thumbscrews to secure them in place.


9. Edge Connectors

Edge connectors or edge card connectors form an external electrical connection by pairing with single-sided or double-sided PCBs. They are embedded on the board and follow industry standard power specifications like power requirements, pin locations, and voltage levels.

The housing is made of plastic while the contacts use metal and come plated with a metallic coating for improved conductivity.

10. IC Interconnect Components

IC Interconnect connectors create a connection between PCBs and microelectronic semiconductor chips. The device closes the gap between two conductors allowing the transmission of current or light waves between the conductors. The package comes with an integrated circuit (IC) on a metal die along with an enclosure made of metal or plastic.

IC Interconnect components are an important part of many present-day electronic systems.

11. Instrument and Computer Power Connectors

Instrument and computer power connectors connect the power supply from the SMPS to various devices such as hard disks, CD and DVD drives, cooling accessories such as fans and thermal coolers and more.

The connectors use a plastic housing with four wires that carry 5V and 12V power and two grounds. They often have different features based on the application.

12. Medical Electronic Connectors

Medical electronic connectors are used in various medical equipment and devices found in clinics, hospitals, and other healthcare facilities. They can be of various types based on application and include circular connectors, coaxial connectors, micro connectors, and heavy-duty rectangular connectors.

Medical connectors can be both male and female.

13. RF and Microwave Connectors

RF and microwave connectors connect the end of cables of devices that use radio frequency or microwave spectrum. The connectors are used to transfer electromagnetic energy and RF signals in case of wireless broadcasting or communication.

The connectors are also commonly found in transmission systems and can couple and uncouple system components.

14. Solar Connectors

Solar connectors are quite common in solar energy systems. The connectors can establish a connection between the solar modules and set up a complete electrical system for your property.

You will mostly see the MC4 (multiple contacts, 4 mm pin) connectors which match with most models of solar modules. The male and female ends can be easily connected using hands, though you will need a tool to detach them.

15. Solenoid Valve Connectors

Solenoid valve connectors are used to form a connection between pressure switches and solenoid valves. The valves also serve the purpose of environment-proof junction boxes and can work with AC or DC voltages. The security boxes can function with pressure switches or solenoid valves.

Solenoid valve connectors have various standard specifications and feature options.

16. Terminal Blocks

Terminal blocks small insulated blocks that connect two or more wires. You can use terminal connectors to fix or terminate wires, and they come with multiple individual terminals. Terminal blocks are often used to secure wiring to ground, or connecting switches to the mains.

You can purchase terminal blocks with a different number of terminals and wire sizes.


17. USB Connectors

USB connectors can connect devices using the Universal Serial Bus (USB) standard ports. USB has high data transfer speeds of 12 Mbps in the 1.1 version. Different computer devices and peripherals use USB connectors to connect with the PC, and even smartphone chargers need them.

USB connectors are available in USB-A, USB-B, UBS-C, and mini/micro-categories. USB comes with hot plugging and plug-and-play feature.

18. Wire to Board Connectors

Wire to board connectors are connectors attached with wires which interconnect PCBs. The terminals are placed in individual housing to establish connectivity between circuits. The connectors feature a locking technology to secure them in place.

You can find a wide variety of wire to board connectors including FFC connectors, IDC connectors and RMC connectors. FFC connectors are ideal for connecting a bunch of wires to carry data from the board to board or from one part of a board to another

19. Wire to Wire Connectors

Two wire-terminated connectors can be connected using wire to wire connectors. They can serve as electrical connectors, electronic connectors or computer connectors. Male wire to wire connectors plugs into the female wire to connectors to form a connection.

Chapter 3: Material of Connector

Electronic or electrical connectors are made up of insulating and conductor materials. The common materials used to make connectors include plastic and metal, though you can also use other materials. The conducting material is of importance as they impact the electrical contacts such as mechanical durability, conductivity, resilience, and formability.

Some common terminal materials you can use are-


Brass is the cheapest metal you can use in terms of weight. Generally, the zinc content in brass can range between 5% to 40% based on the application. Brass offers considerable strength, good spring and adequate electrical properties.

Brass connectors are mainly used for KK terminals.

Phosphor Bronze

Phosphor bronze is tough and offers increased strength compared to brass. It comes with impressive conductibility and superior fatigue resistance. Phosphor bronze also has excellent elasticity making it suitable for use in electrical contact springs.

Beryllium Copper

Beryllium copper is the best type of copper alloy for spring terminals. It contains around 0.5% to 3% beryllium with other elements. The alloy offers high strength and is cheaper than phosphor bronze.

High Copper Alloy

High copper alloys contain a high percentage of copper (more than 96%) and are suitable for demanding applications. The alloys have high strength coupled with excellent thermal and electrical properties. You can also use them in high-temperature settings as they don’t soften easily.

High copper alloys are mostly used in automotive applications.


In the next chapter, we will cover the considerations when choosing electronic connectors.

Chapter 4: Factors to Consider When Purchasing Electrical Connectors

You have to consider many factors to choose the right connector for your application. Many types of connectors are available in the market, so make sure you choose wisely. Here are a few factors worth considering-


Cost is usually an important consideration for many engineers and manufacturers. After all, you want to have the best at the lowest price possible, right?

Even that is your goal, don’t make the mistake of choosing your connectors based on the only cost. You may end up with cheap products which don’t do their job and lead to the failure of your project.

So always look for quality and try to strike a balance with cost to enjoy the maximum cost-effectiveness.


The environment where you will use the connectors is also crucial. Will the connectors be used on bare ground or in the water? Or in a boat? Will the connectors encounter extreme weather? Will the project involve vibrations and shocks?

Select the best connectors based on your use environment. You should go for connectors with environmental sealing if you need protection against dust, vapor, liquids or combustible gases.

Determine the level of safety you require and then choose the connectors. Also, keep the operating temperature range in mind while making your selection.

Signal Type

You will need to choose the connectors based on the signal they transmit. Signals can be analog, digital, or a combination of both. If the signal is analog, then what is the frequency? Does it involve audio or RF? What is the bit rate or clock speed for analog signals?

The type of signal decides the type of connector, pinout, and wiring you will need.
Remember that you cannot use certain signal combinations in the same connector. You will need to consider clearance distances and creepage for high-voltage pins. You can also go for a custom solution based on your unique needs and design specifications.

Power Level

The level of current passing through your connector will also influence your choice. For high current paths, you will need multiple larger and thicker pins. If you are dealing with high voltage, then go for a connector with more insulation. For high voltage pins, you may also need to consider clearance distances and creepage.


The frequency of your terminals determines the strength of the connectors you need. Will the terminal be often plugged in and plugged out? Choose a connector with appropriate ruggedness based on your application.



Electrical connectors are important for the smooth operation of any electronic equipment. It’s always wise to go for reliable and quality terminals which ensure the success of your project. Get in touch with us today to get more information on electrical connectors and custom solutions.

SATA Cable – The Guide to Getting the SATA Cable They Need(2019)

SATA Cable

A SATA Cable connects storage devices like a hard disk, optical drive, etc. in a computer to a motherboard. Earlier, all the devices used a PATA cable for the connections, but an upgraded SATA succeeded it. What is a SATA Cable, and what are its applications?

This article will explain all the features and applications of a SATA Cable to you. You’ll learn about the kind of connectors that are compatible with the cable. You’ll learn how it’s different from the PATA cable. And you’ll read about the place it holds in today’s world. 

SATA Cable

Chapter 1: Serial ATA (SATA) Cable?

1.1 What is the SATA Cable?

The Serial Advanced Technology Attachment (also known as Serial ATA and SATA) cable is an Integrated Drive Electronics standard computer bus interface. A SATA cable connects a host bus adaptor like a motherboard to mass storage devices like optical drives, hard disk drives, and solid-state drives.

Earlier, PATA or Parallel ATA cables were the dominant interfaces for storage devices. SATA was introduced as in 2001 an update to PATA cables as they can transmit the data much faster.

A SATA cable uses a 7-pin connector that connects the hard drive to the motherboard. The same cable is also used to connect to other SSD devices. One can also connect an external hard drive to the computer with a SATA cable through the eSATA input.

1.2 Features of SATA cable

Following are the features of a SATA Cable:

        Simplified Cabling: Compared to the 40-pin and 80-wire PATA, SATA uses a seven-wire cable. Not only does it reduce cost, but also eases cable routing and improves the airflow and cooling.

        Robust data: The SATA cable uses a differential transmit pair, and a differential receives pair. That accounts for a higher degree of error detection and correction, as well as high-speed data transfers.

     Hot Plug: Hotplugging enables the insertion/removal of a device from the connector while the power is on. The devices install and operate normally as soon as it’s connected to the computer. SATA cable supports hot-plugging by design.


PATA, also known as Parallel ATA, is also an IDE standard for connecting storage devices to the motherboard. Earlier known as ATA, the cables were renamed to parallel ATA after serial ATA was produced.

Compared to the 100 MBps of the fastest PATA, SATA has a much faster transfer rate of 150 MBps. Apart from that, SATA has several advantages over PATA. SATA drives have an independent bus. They also use thinner cables that support better airflow. SATA cables are also longer than the PATA cables and can go up to one meter. It gives the manufacturers more liberty while designing the layout inside the computer.

SATA also uses only seven conductors compared to the 40 of PATA. It decreases the potential electromagnetic interference that the devices may have. SATA also supports hot plugging in the devices, which means that one can remove a device without switching off the computer. But the entire computer needs to shut down before plugging off a PATA device.

However, SATA cables also have a few disadvantages against a PATA cable. A SATA cable has only one device connected to it whereas a PATA cable can have two. Though most operating systems support SATA, the older ones like Windows 95 and 98 don’t. Some of the SATA cables also need a special device driver before data transmission.

SATA Cable

 We’ve learned about the SATA cables and how they’re different from the PATA cables. We will not further study their applications. 


Chapter 2: The Applications of SATA Cable

SATA cables are used for both data transmission and to provide power to the data drives and SSDs. In this chapter, we’ll take a look at different types of SATA Cables and their applications.

2.1 SATA Cable for SSD

SSD are storage devices that work faster than traditional and mechanical hard drives. These drives don’t have performance issues as compared to the older storage devices. A SATA cable is used for connecting the SSD installed as an internal device in the computer.

A SATA cable with a power connector provides power supply to the SSD device. These cables stuck out from the SMPS of the CPU and hooked on to the connector in the SSD. These cables are known as the SSD Power cables.

2.2 SATA Cable for HDD

The Hard Disk Drive cable is a SATA cable that connects the hard disk to the motherboard. This cable is also responsible for providing the power supply to the hard disk. A hard disk consists of several inlet ports out of which, one is compatible with the SATA cable.

The ends of the SATA cable are connected to the hard disk and the SMPS of the CPU. Earlier, four-pin Molex connectors were used for these connections. But the new SATA Cables are thin and have a flat surface which maximizes the airflow inside the CPU. It ensures better performance of the HDD.

A SATA Cable can also be used to connect an external hard drive to the computer.

An external hard drive can be connected through an ESATA input. If the hard drive supports a USB input, you can also use a SATA to USB converter to connect the device to the computer.

SATA Cable

2.3 SATA Cable for Laptop

In most laptops, the storage devices are directly attached to the motherboard. Therefore, a traditional SATA cable isn’t required. The storage devices in the laptops like HDD, SSD, etc. are connected to the breakout boards. These boards are connected to the motherboard with a ribbon-like SATA cable. These cables are thin and flat, allowing airflow in the laptop.

2.4 SATA Cable for Multimedia peripherals

The SATA cables for multimedia peripherals are power cables that connect them to the device or the power source. The cable can consist of two female ports that connect the peripheral to the CPU. Another type of cable includes a female port at one end and an AC plug at the other. They connect the peripheral directly to the power source.

 2.5 SATA Cable for Mid-range servers

The SATA cables for mid-range servers have a port at both ends for the connection. One end of the cable is connected to the server and the other to the CPU. These cables are longer and have a wire-like structure that makes them more flexible. They transmit the data at a much faster rate and are very efficient.

SATA Cable

2.6 SATA Cable for Storage systems

The SATA cables for storage system have flat ends and ribbon-like structure for internal and external connections. The flat port allows more data transfer. The ribbon-like structure promotes flexibility and airflow. It keeps the large systems from heating up and makes for an efficient flow of data.


Chapter 3: SATA Cable Connector

The SATA cable connectors are visibly different from the PATA cable connectors. They use the same connectors for the 3.5-inch hard disks for computers and the 2.5-inch disks for portable computers. Both data and power SATA connectors have a conductor pitch of 1.27 mm. These conductors need a very low insertion force for connection. They have right and left-angled connectors for ease of connection. SATA data cables for motherboards come with locks on their female ports to prevent accidental unplugging.

Following are the features of the SATA cable connectors:

3.1 SATA DATA Cable Connector

A SATA Data cable has 8mm wide wafer connectors on each end. These connectors have seven conductors and can be up to one meter long. These connectors have their either ends connected to the motherboard and the hard drive. In comparison, PATA cables are 45 cm long and have a ribbon-like structure. They can also connect one motherboard to one or two hard drives.

The SATA connectors are easier to fit in less surface area and give more room for cooling. The connectors with locks hold the plug in the socket and reduce the risk of accidental unplugging.     The differential signalling in the SATA connectors reduces the loss of data during data transfer.

3.2 SATA Power Cable Connector

The SATA power connector is different from the four-pin Molex connector used with a PATA cable. The SATA power cable connector consists of a wider wafer-type connector with 15 pins. The earlier versions of this connector also included the four-pin Molex connector.

These connectors supply an additional 3.3 V along with the traditional 5V and 12V. Three parallel pins supply each of these voltages. These pins help reduce impedance and increase current capability.

SATA Cable


Chapter 4: Types of SATA Cable

 4.1 E-Sata:

These are wires that connect to your computer or laptop externally and aren’t longer than 2 metres.

4.2. Low Profile SATA:

If you’re low on space and have a long graphics card, you’ll need this. These low profile connectors can work magic.

4.3. Micro SATA:

Designed for internal drives, this Micro SATA cable ensures that backplane operations are a breeze.

4.4. SATA Bracket:

These are dual port expansion brackets that aim to make your computer work with ESATA drives.

4.5 SATA Bridge:

If you have an ATA device that you’re looking to connect to a SATA motherboard or a PCI card, you will need this.

4.6 SATA Power:

These are power and data cables that are designed to work with power adaptors, extensions and splitters without a hiccup.


If you’re looking for standard SATA cables, this is what you need. You can find them in different lengths too, so take a pick according to what you are looking for.


Chapter 5: More about SATA Cable & Connectors

A SATA cable can also be used to connect external drives. The SATA drives can also be plugged into SAS controllers and communicate similarly. There are also several SATA connectors that can convert an old IDE device into a SATA device. There are also converters that make a SATA cable compatible with a USB port.

5.1 External SATA Cable (eSATA Cable)

External hard drives can also be connected to the computer the same way the internal ones can. If the hard drive has a SATA cable port, an external SATA cable (eSATA) is used for it the connection. An eSATA port opening is on the computer right next to the ones for the monitor, network cable, and USBs. This port is connected to the motherboard inside the computer, like a usual SATA connection.

The SATA cables are also hot-swappable and can be taken off when the power is on. However, unlike SATA cables, they only transfer data and not power. Thus, an eSATA cable requires a separate power adaptor plugged into the wall for its functioning. The ESATA cables also have a different connector as compared to the SATA ones. It prevents the use of SATA cables for external purposes. 

SATA Cable

5.2 SATA Converter Cables

Many old devices aren’t compatible with SATA cables and still use the Molex connectors. Thus, you can use Molex converter cables that provide power to the internal 15-pin connection of the SATA cable. Similarly, a lot of new hard drives come with USB ports than SATA ones. Thus, you can make use of a SATA to USB converter cable. This cable helps you in backing up the files on the drive, browse the data, as well as clean it.

5.3 SATA Extension Cable

A usual SATA cable is about 1 meter long and works well for an internal connection. However, upgrading or building a new connection demands more flexibility. As a result, stretching or straining as the old cable can cause damage to the system.

A SATA power and data extension cable can stretch up to 1 foot. The cable helps in overcoming the limitations of a typical connection. It also reduces the risk of damaging the motherboard or the drive. It also helps in extending the backplane adaptor connections and drive dock connections.

 5.4 SATA To USB Cable

Now, you need a USB cable for pretty much everything. Wouldn’t it be great to add in SATA to a USB cable? While USB cables may be long, what do you do if you need a SATA connection? It could be for a laptop data transfer or to use with your SSD drive. A SATA to USB cable will make things easier for you, working with your laptops and other devices seamlessly.


Chapter 6: How Important is SATA Today?

SATA cable was one of the most used cables in the early 2000s in the PC. However, the world has moved on to faster standards like PCI-express for its storage connections. The laptops, too, come with built-in memory for their devices.

SATA cables are still important for larger hard drives and multi-terabyte SSDs. But options like M.2 and NVMe give better performance for a high price range. Plugging into a PCI-express slot also reduces the hassles of a SATA cabling and gives a faster data rate.

SATA cables play an essential role in powering up as well as transmitting data between the storage devices and the computer. But, with time, these standards are being replaced by better and faster alternatives.

Audio cables are used to transmit signals properly and curb interference of noise, which can distort the proper dissemination of information.

1.2 Basic Components of the Audio Cable

a. Conductors: This is popularly referred to as the powerhouse of the cable. It is also considered to be an intricate part of the structure. Its make -up is copper or silver coated copper. Conductors house the gauge of the cable and the efficiency of the cable to a large extent depends on the size of the gauge.

b. Dielectric: It covers the conductor just like an insulator. Dielectric is made up of foam polyethene. The covering of the dielectric determines the ability of the cable to withstand electrical current. It is essential because, without this quality, electrical appliances stand a risk of explosion. For this reason, the source and cable must share a similar quality.

c. Shield: This provides coverage for the conductor. It protects it from disturbing noise that can mitigate its signal transmission. The higher the chances of coverage, the more sophisticated protection the shield assumes.

d. Jacket: It is made up of Poly Vinyl Chloride. It protects the inner material.

e. Connectors: This help connects the cable plug to various electrical appliances; such as computers, musical instrument, speakers, and so on.

Furthermore, audio cables do not exist in isolation but depend on these various basic components to ensure it works properly.


Chapter Two:Types of Audio Cable

There are four major types of audio cables. We have the Analog RAC cable, speaker cable, optical digital cable and coaxial digital cable.

2.1 Analog RAC Cable

Analog RCA cables date as far back as 1960. They are used for connecting old and new components. They are helpful in the connection of microphones, DVD players and so many more to stereo receivers. Additionally, they can be used for digital enhancements. These cables are not compatible with long distances, and they could become unstable. If the distance is wide apart, it may impair the sound quality, especially when there is a ground loop. Ground loops are present when different equipment isn’t properly connected, and a loop is created.

2.2 Speaker cable

These are used to transmit signals from a stereo receiver to a speaker system. Speaker cables are not balanced cables but are of utmost importance in transmitting audio signals. Speaker cables affect the sound quality if the length of the cable is considered too long when the cable has a poor composition and a poor gauge.

2.3 Optical Digital Cables

It is one of the finest births of audio cable technology. It aids the transmission of digital sound with light pulses and ease. The signal must first be translated from the electrical signal to an optical one. These cables are not easily affected by external sources which may emit from Radio frequency interference because light doesn’t suffer the resistance that occurs in copper cables. They have a thick guard from external interference and don’t lose their signal over long distances.

2.4 Coaxial Digital Cables

Coaxial Digital Cables are advanced audio cables which are used to transmit digital signals between components. Coaxial cables are vulnerable to radio frequency interference. That is, if there is any external interference within the system, the coaxial cable easily transfers the distracting sound between the components. These cables impair the quality of sound over long distances.


Chapter Three:Types of Audio Cable Connectors

Audio cable connectors are electromechanical devices that link the audio cable with the output device. Connectors are classified with the kind of signal it transmits. To be regarded as a sound professional, it is pertinent to have in-depth knowledge about connectors to understand its various uses. Connectors are grouped as balanced and unbalanced connectors. The various kinds of connectors can both be used by different professional and individual consumers. These connectors come at different prices and different quality levels. The basic types of audio cable connectors are:

3.1 Analog audio connectors: 

Analog audio connector is an output that is found on some home electronics such as DVD players and VCRs and is used to connect analogue audio cables to receivers and TVs. The various types of analogue audio connectors are:

a. RCA connectors: RCA connectors are unbalanced connectors which are used by a large number of professionals. Connectors are used for connecting home stereo systems, video cassette recorders and so on. They are responsible for ten dB (consumer) line levels.

b. XLR connectors: Professionals predominantly use these connectors. There are three types of XLR connectors. They are XLR male, XLR female and TRS. Each of these XLR connectors has three contact points that transmit signal from the ground, positive and negative wires.

i. XLR male: This is essential for connecting a variety of hardware inputs.

ii. XLR female: It is important for establishing a connection between a microphone and a variety of hardware inputs.

iii. TRS: This XLR connector connects both the input and output devices.

c. ¼ Audio connectors: These connectors are generally regarded as phone plugs. They are used to connect cables with various professional and consumer musical equipment such as speakers, musical instruments, amplifiers, and so many more.

3.2 Digital Audio Connectors:

 Digital Audio Connectors are more advanced than analogue audio connectors. Nonetheless, analogue connectors can transmit digital signals just like digital connectors. Some types of Digital Audio Connectors are:

a. S/PDIF: This is an acronym forSony/ Philips Digital Interface Format. It is used for recorders, CD players, DVD players, MiniDisc equipment, consumer level AES/EBU digital audio protocol and some audio interfaces.

b. AES/ EBU: This abbreviation means Audio Engineering Society/ European Broadcasting Union. They are used in a professional setup.

c. TOSLINK Optical and AdatLightpipe: It is the most frequently used digital connector that can transmit different digital signals formats. These formats are:


ii. AC-3 and DTS

iii. ADAT Lightpipe

There are varieties of audio connectors on the market. For best results, it is important to learn about audio cables and the connectors that work best.


Chapter Four:3.5 mm Audio Cable VS ¼ Audio Cable

3.5 mm audio cables are used for consumer electronic devices like camcorders, cameras and portable DVD players. They ensure the proper transmission of audios and videos. The 3.5 mm audio cable can also be attached to factory stereo and external sources such as a portable MP3 player or another source. There are quite several 3.5mm audio cables. These cables are used in various capacities. Examples are: Gold plated 3.5mm stereo audio cable to female extension cable, 2- pack 3.5mm stereo audio cable, gold plated 3.5mm to 2- RCA stereo audio cable, two pack, 3.5mm coiled stereo audio cable in black 5Ft and gold plated 3.5mm stereo splitter 8 inches.

On the other hand, ¼ audio cables are used for musical instruments. Unlike 3.5mm audio cables, 1⁄4 cables are connected to instruments such as guitars and keyboards. It is known as the most versatile audio connector. This cable does not perform the same function as 3.5mm audio cables. For the 3.5mm audio cable, it is easier to transmit stereo signals, but not with 1⁄4 audio cables. When connecting the ¼ audio cables to instruments, it is safer to purchase instruments cables alongside.

The major difference between the 3.5mm audio cables and ¼ audio cables is the structure. While the former can be dual plugs, the latter is generally mono-like. Furthermore, the capacity of both cables varies. 3.5mm is used for consumer electronic devices and can be used for stereo too, but ¼ audio cables are used for musical instruments.
