DIN Connector – Everything You Need to Know

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

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

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

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 millimetres.

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 interface 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 encompasses a great number of interfaces, including digital and analogue. Their applications include home theatre and portable use to the pro audio mixing boards that DJ’s and professionals use. The similarity between most audio connectors is that they are easily connected.

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

We can take an example of a stereo tape recorder. To connect the stereo tape recorder with a stereo amplifier, we use five pin din connector. 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 outside the connector, with five pins upward and facing them: (1-4-2-5-3).

male plug connector

Female connector

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

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

II. Other users

Others use the 5/180,” which include:

i. SYNC or MIDI interface for electronic musical instruments.

ii. Peripherals or power connectors for personal computers.

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

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

cable connectors

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 Connector?

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 limiting the orientation in which the plug and socket can connect.

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 carries digital system data. If the equipment is incompatible, then the outer two pins from the plug should unscrew. That is why we fit them into standard five pins 180” sockets without data connections.

N-type connector


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

loudspeaker connector


In the speaker connector, terminals are in pairs, so the two wires of the speaker cable connected to one terminal. Since the speaker cables are polar, they are often colour 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 circular pin mounted at
The centre. The female version is available with or without an auxiliary contact. It disconnects the internal speaker whenever an external speaker connects to it.

Din radio connector

The three-hole female connector is the most common that 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 it, such as 16mm film projectors. Becker radio in Mercedes Benz, LED lamps and halogen lamps connect the bulbs to power supply also have this. 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 pins electrical connectors which have used in multiple applications. DIN and multi DIN, both are standards of Deutsche Institut fur Normung, the German standards body.

Mini Din comes in seven patterns and has several pins varying from three to nine. They have 9.5 millimetres that are 3/8 inches in diameter. the pattern has a key so that a plug with one pattern cannot mate with any socket of another pattern.

Each pin has a different pin arrangement, square key size, and position. Each 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 to each other. At the same time, the standard mini Din has no simultaneous and direct overlapping similarities.

nonstandard four-pin mini din

A lot of nonstandard mini Din connectors have designs that mate with standard mini Din plugs. The advantage of a nonstandard Din connector is that they provide extra conductors. They have used in saving space by combining functions in one connector, using 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 millimetres of body.

These mini Dins without the Deutsche Institut fur Normung approved, it is the German standards body. Several applications are proprietary of these mini Dins.

Chapter 5 Benefits of buying DIN Connector

Din connectors have many benefits, which are 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 a variety of sources as pre-wires, moulded and tested.


The pre-wired design allows you to use the Deutsche technology on applications that already have the DIN style in place. Or where there is not an 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. If you want to have good quality and long-life products, finding a professional manufacturer is significant.

Manufacturing organisations 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, 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 it.

It is better if someone contacts 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.

Before buying a din connector, you need to confirm everything and double-check it in case of any misunderstanding.

Step 3: DIN Connector–Sign the contract

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

confirmation letter

It is a rule in business deals to sign a contract before collaborating. If any big order signing a contract is just like making a promise which 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 need to ask for the sample first. 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 ConnectorDelivery 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, deliver to the customer, and charges and stuff. These are essential questions asked by a customer, and which they should answer honestly.

delivery service

It is important to find a good delivery service, and it’s most convenient if the company itself 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.
