A DIN connector is an electrical connector that was originally standardized in the early 1970s by the Deutsches Institut für Normung (DIN), the German national standards organization.

A DIN connector encompasses several types of cables that plug into an interface to connect devices. It has an architecture that is composed of multiple pins that are within a protective circular sheath. Typically, a full-sized DIN connector has three to 14 pins with a diameter of 13.2 millimeters.

In computer electronics, the DIN connector is referred to as a circular connector that is DIN standardized and used for digital interfaces like the musical instrument digital interface (MIDI), the IBM AT computer keyboard or mouse, and in analog video architectures. Original DIN standards for older connectors are no longer in print and have been supplanted with the corresponding international standard IEC 60130-9.

There are seven familiar patterns with three to eight pins with different five-pin connectors: 180°and 240° or 270°. The 180° five-pin connector was sometimes used to connect a stereo recorder to an amplifier using four of the pins for a connection and one to ground. This was sometimes called a DIN cord, DIN lead or DIN cable.

The 3/180° and 5/180° connectors were originally designed to connect analog audio equipment such as stereo tape recorders to amplifiers or preamplifiers using four pins to connect and one to ground the system. The cable has a connection on both ends with each pin matching up to the other pin.

S-video (short for Super-video) is an older type of video signal that’s transmitted in varying electrical signals over wires to represent the original video. Newer video cables like HDMI transmit digital video signals in the form of numbers representing the original video signal. The benefit of digital video is that the signal doesn’t degrade from source to destination. It’s also capable of transmitting much higher resolution video.

MIDI = Musical Instrument Digital Interface

MIDI, the digital communications protocol, introduced in 1983 by a group of musical instrument manufacturers. They agreed on the ‘MIDI 1.0’ specification. All instruments using the MIDI port must be compatible to the MIDI standard and instruments of different manufacturers should work together.5-pin, 180 degree, DIN connector (DIN 41524).
