DIN Connector – Everything You Need to Know

Looking for circular connectors that can connect to plugin connectors? Or circular connectors that you can use for computer data and video? You are looking for DIN connectors, electrical connectors used in personal computers. It connects routers or switches.

DIN connectors are used in various applications ranging from audio and video to power, serial, and data.

Today, we will talk about Din Connectors, their types, different pins, shapes, orientation, usage, and much more.

DIN Connector 1

Chapter 1 What is DIN Connector?

DIN Connectors were originally brought into line in the 1970s. It is an electrical connector, and its architecture has multiple pins under a protective circular sheath.

Normally, a full-sized DIN Connector contains three to 14 pins with a diameter of 13.2 millimeters.

DIN Connector 2

The term Din connector doesn’t refer to a specific cable. Instead, it requires all the connectors that meet the Din standard.

The circular connector is another name for Din Connector in computer electronics. It’s also used for a digital interfaces such as musical instrument digital interfaces MIDI.

Chapter 2 Applications of DIN Connectors

There are two applications of Din Connectors.

1. Analog Audio

2. Other users

I.Analog Audio

AUDIO CONNECTORS encompass a great number of interfaces, including digital and analog.

Their applications include home theatre and portable use to the pro audio mixing boards that DJs and professionals use.

The similarity between most audio connectors is that they are easily connected.

DIN Connector 4

The 3/180″ and 5/180″ connectors were originally systematized. European countries widely used them for connecting different audio equipment.

We can take an example of a stereo tape recorder. We use a five-pin din connector to connect a stereo tape recorder with a stereo amplifier.

The din connectors distinguish into two connectors, male and female connectors.

Male connector

The pins have their numbers on the male connector from right to left. We view them from outside the connector, with five pins upward and facing them: (1-4-2-5-3).

DIN Connector 5

Female connector

Holes on female connectors have their numbers from left to right, facing the holes: (1-4-2-5-3). This way, a four-conductor cord wire is sometimes called a DIN lead, Din cable, or DIN cord.

For mono interconnections, 3/180” plugs are enough.

DIN Connector 6

II. Other users

Others use the 5/180,” which include:

1. SYNC or MIDI interface for electronic musical instruments.

2. Peripherals or power connectors for personal computers.

3. If you want to connect to controllers for radio-controlled model aircraft together for training purposes.

4. Controlling tilt of UT MS antennas (Antenna Interface Standard Group)

DIN Connector 7

The DIN connector has several other uses other than audio. It is particularly famous as a connector for various home computers and video games.

Chapter 3 What are the Types of DIN Connectors?

There are mainly two types of DIN connectors. We will discuss them briefly one by one.

• Circular connector

• Loudspeaker connector


Circular connectors consist of a family of male plugs. They have the same feature of a 13.2-diameter metal shield with a notch that limits the orientation in which the plug and socket can connect.

DIN Connector 8


There are seven common patterns, which can be any number from three to eight pins. When some high-range equipment uses seven-pin connectors, then the outer two carry digital system data.

If the equipment is incompatible, then the outer two pins from the plug should unscrew.

We fit them into standard five-pins 180” sockets without data connections.

DIN Connector 9


Loudspeaker connectors are a type of electrical connector. They connect speakers and audio power amplifiers.

DIN Connector 10


The speaker connector terminals are in pairs, so the two wires of the speaker cable connect to one terminal in pairs.

Since the speaker cables are polar, they are often color-coded. So the circular pin connects to the positive line (red) and negative line (black).

Many early shoe cassette recorders used DIN 41529 speaker connectors. It exists as a panel-mounting female version and line-mounting male and female version.

The male version has a central flat pin and a circular pin mounted at The center.

The female version is available with or without an auxiliary contact. It disconnects the internal speaker whenever an external speaker connects to it.

DIN Connector 11

The three-hole female connector is the most common and has one circular hole on either side of the spade hole. One has auxiliary contact.

One has no. It provides the option to leave the internal speaker connected by inserting a plug by twisting it 180”.

speaker line socket and plug

Older devices generally use, such as 16mm film projectors. Becker radio in Mercedes Benz, LED lamps, and halogen lamps connect the bulbs to the power supply also have.

There are also three- and four-pin versions of this loudspeaker connector used, for example, by Bang and Olsen.


What is Mini-DIN Connector

Mini-DIN connectors are smaller in size, but they are similar to larger and older DIN connectors. It belongs to a family of multi-pin electrical connectors used in multiple applications.

DIN and multi-DIN are both Deutsche Institut fur Normung standards of the German standards body.

Mini Din has seven patterns and several pins varying from three to nine. They have 9.5 millimeters that are 3/8 inches in diameter.

Each pattern has a key so that a plug with one pattern cannot mate with any socket of another pattern.

female mini Din

Each pin has a different arrangement, square key size, and position. The pin also has circular metal shielding skirt notches and metallic additions.

That is why all the seven Dins are official standards because each pin is drastically different from the other.

Chapter 4 Application of Mini-DIN Connectors

NON-Standard Mini DIN Connectors

Nonstandard mini Din connectors may have direct overlapping characteristics with each other. At the same time, the standard mini Din has no simultaneous and direct overlapping similarities.

nonstandard four-pin mini din

Many nonstandard mini Din connectors have designs that mate with standard mini Din plugs. The advantage of nonstandard Din connectors is that they provide extra conductors.

They have been used to save space by combining functions in one connector, which would otherwise use two standard connectors.

Other nonstandard connectors only mate with their matching connectors. The thing that makes them mini Din connectors is that they share 9.5 millimeters of body.

Without the Deutsche Institut fur Normung approval, hesemini Dins are the German standards body. Several applications are proprietary to these mini Dins.

Chapter 5 Benefits of buying DIN Connectors

Din connectors have many benefits, evident from using Din-style cables for mobile machinery.

Din connectors particularly use on pressure switches, solenoid valves, and other devices. We can order them from various sources as pre-wires, molded, and tested.


The pre-wired design allows you to use the Deutsche technology on applications with the DIN style in place.

Or where there is no option to change the product to Deutsche connectors directly at the source. Plugin the adapter, and you’ve now changed the connector style to Deutsche.

Chapter 6 How to Custom DIN Connector Step By Step?

Step 1: DIN Connector–Finding a professional manufacturer

The first step is crucial. The quality of the product depends upon the manufacturer. Finding a professional manufacturer is significant if you want good quality and long-life products.

Manufacturing organizations tend to attract the attention of the general public the way airlines do. One only notices them when they’re late, when ticket prices rise, or when there’s a crash.

types of connectors

Switches, plugs, and connectors are essential in our daily life. We need to connect to several things every day. The material of these things matters a lot as it can destroy the things connected to them.

It is better to contact a well-known or trusted manufacturer who can make a good quality product.

Step 2: DIN Connector–Drawing confirmation.

Making confirmation is very important as there are a lot of parasitic manufacturers.

Step 3: DIN Connector–Sign the contract.

Sometimes a handshake is not enough; written papers are important, especially when buying or selling something.

confirmation letter

It is a rule in business deals to sign a contract before collaborating. In the case of any big order signing a contract is just like making a promise that one shouldn’t break; it doesn’t mean you don’t sign during small orders. Everyone should sign a contract before paying money.

Step 4: DIN Connector–Sample confirmation

To get the correct order, you must first ask for the sample. Don’t be afraid to ask the manufacturer for the sample; it is your right to ask him. A good manufacturer makes sure to satisfy its customers at any cost.

sample test

There have been many cases when people got the wrong order and manufacturers refused to pay it back, so one should be careful while ordering. The reliability of the manufacturer is critical.

Step 5: DIN Connector–Delivery to customer

It is necessary to know the details of the product and the company manufacturing it. Whenever you order something, you need to know how long it will take or when it will deliver to the customer, and charges and stuff.

These are essential questions a customer asks, and they should answer honestly.

delivery service

Finding a good delivery service is important, and it’s most convenient if the company offers a delivery service.

Usually, it takes two to three weeks to make a connector, but it can take several months if you want to output it from the outside.
