DIN Connector: Types, Application, and More

DIN Connector

DIN Connectors are electrical connector that is identified by its Deutsches Institut fur Normung, also known as DIN, is the entity that developed the DIN standard.

Any specific kind of connector without a corresponding number is not covered by the definition of the standard term DIN connector.

What Are DIN Connectors?

DIN is an abbreviation for German Institute for Standardization is a group that develops standards for the country’s manufacturing sector. Round DIN connectors have a circular arrangement of pins. PC keyboards, MIDI instruments, and other specialized equipment frequently used this kind of connector.

Another type of DIN connector is the mini-DIN. Mini-DIN connectors are, as the name implies, smaller than standard DIN connectors. They are still round, but the pins are arranged in horizontal rows as opposed to a circle. S-video connections, PS/2 mice and keyboards, as well as some other uses, all use mini-DIN connectors.

DIN and mini-DIN connectors are both held in place by the friction of the connector body and by pins.

Techopedia Explains DIN Connector

A DIN connector is a type of electronic cable that was widely accepted as the standard for many years and for various applications. It is made up of a shielding metal skirt with pins that are all straight and round. In order to enable proper plug insertion and guard against pin damage, the skirt has been carefully keyed. All original DIN connectors have uniform keying, though, and if the wrong mate is accidentally connected, damage could result. The Mini-DIN was invented to avoid potential misconnections.

Seven well-known patterns, 180°, 240°, or 270°, are available with three to eight pins on various five-pin connectors. Four of the five pins on the 180° five-pin connector were used to connect a stereo recorder to an amplifier while the fifth pin served as ground. A DIN cable, lead, or cord may also be used to describe this.

Originally, the 3/180° and 5/180° connectors were made to connect analog audio devices, such as stereo tape recorders, to amplifiers or preamplifiers using four pins for connection and one for system grounding. Each pin on the cable matches the other pin on the other end, forming a connection.

The 5/180° connectors are normally used for various applications like:

  • Control interface for antenna line devices
  • Serial ports in the original Apple IIc computer
  • MIDI interface for electronic musical instruments
  • DIN sync interface for electronic musical instruments
  • Connecting two controllers for radio controlled model aircraft
  • Audio equipment such as the original HME wireless communicators and inbound/outbound audio for drive-through restaurants
  • Keyboard and mouse connectors for the original IBM PC and IBM Personal Computer

What Are the Types of DIN Connectors?

There are mainly two types of DIN connectors. Each one will be briefly covered in this discussion.

  • Circular connector
  • Loudspeaker connector

Circular Connector

Circular Connector

There is a family of male plugs used in circular connectors. They share the same 13.2 diameter metal shield with a notch that restricts the direction in which the plug and socket can connect.

Loud Speaker Connector

Electrical connectors of a certain kind include loudspeaker connectors. They link audio power amplifiers and loudspeakers.

Design Structure

Based on the material used to make DIN connectors, various gasket options are available, including NBR profile, NBR flat, and EPDM flat. Here, EPDM rubber can withstand weather, ozone, and heat well, while NBR rubber, an oil-resistant substance, stands for nitrile rubber.

The thread types for the cable entry solely depend upon the form you choose such as the Form A connectors are available in PG 9, PG 11, M16 threads, Form B connectors are available in ½” Only the PG 7 thread is suitable for NPT threads and Form C connectors.

On top of that, each form consist of different pin spacing and pin type options such as the Form A connector has a “U” shaped pin facing with an 18 mm pin spacing, Form C connector has flat blade pins with a 9.4 mm or 8 mm pin spacing, while Form B connector has pins with a 10 mm or 11 mm pin spacing.

Application and Benefits

The application of DIN connectors can be found in a diverse range of electrical products such as in conjunction with pneumatic devices, in hydraulics machines and machinery, electromagnetic devices, including solenoid valves.

Numerous electrical and electronic products, including limit switches, pressure transducers, and proximity and level sensors, as well as low-energy motors, make extensive use of DIN connectors.

These DIN connectors offer a variety of benefits that work together to lower application costs. These benefits include enhanced product performance, streamlined manufacturing procedures, and decreased inventory.

DIN connectors are designed to function within specific voltage ranges and have different overvoltage protection requirements met.

How to Custom DIN Connector?

The process for making custom DIN connectors is outlined here.

Step 1: DIN Connector–Finding a Professional Manufacturer

The very first step is essential. The manufacturer determines the product’s quality. Finding a reputable manufacturer is important if you want to have high-quality, long-lasting products.

Similar to how airlines do, manufacturing companies frequently catch the public’s attention. They are only noticeable when there is a delay, when prices go up, or when there is an accident.

Plugs, connectors, and switches are necessary in every aspect of daily life. Every day, we have to connect to a number of things. Because it has the potential to destroy things connected to it, the material of these things is very important.

A reputable manufacturer who can produce a high-quality product should be contacted if possible.

Step 2: DIN Connector–Drawing Confirmation

Since there are many parasitic manufacturers, confirmation is crucial.

You must make sure there are no misunderstandings before purchasing a din connector.

Step 3: DIN Connector–Sign the Contract

Written documents are crucial, especially when buying or selling something, and a handshake isn’t always sufficient.

In business transactions, it is customary to sign a contract before working together. If signing a contract for a large order is similar to making a vow that you shouldn’t break, that doesn’t mean you shouldn’t sign for smaller orders. Before making a purchase, everyone should agree to a contract.

Step 4: DIN Connector–Sample Confirmation

You must first request the sample in order to receive the correct order. Asking for a sample from the manufacturer is something you have the right to do, so don’t be afraid to do it. A good manufacturer will go to any lengths to ensure customer satisfaction.

People have received the wrong orders in numerous instances, and the manufacturers have refused to refund the money, so one should exercise caution when ordering. The manufacturer’s reputation for dependability is crucial.

Step 5: DIN Connector—Delivery to Customer

Understanding the specifics of the product and the business that makes it is essential. Every time you place an order, you need to be aware of the delivery window, cost, and other details. Customers typically ask these crucial questions, and businesses should be honest in their responses.

Finding a reliable delivery service is crucial, and it is most practical if the business itself provides this service.

Making a connector typically takes two to three weeks, but if you want to output it externally, it may take several months.

Conclusion on DIN Connector

There are various cable types that can be plugged into an interface to connect devices, and a DIN connector includes them all. Its architecture is made up of numerous pins encased in a circumferential sheath for protection.

What is the Difference Between DIN and XLR?

Before looking at the actual performance of these connectors I must first explain that RCA can only support a “single ended” electrical interface, DIN typically supports a single ended electrical interface and XLR typically supports a “balanced” interface.

Is DIN and MIDI the Same?

NO, a “DIN cable” is NOT the same as a “MIDI cable” unless you can prove it.
