What Is a DIN Connector?

The DIN connector is a connector standard developed by the German Standards Institute (DIN, Deutsches Institut für Normung eV). Because there are too many DIN connector standards, the term DIN connector does not represent any kind of connector without additional numbers (such as "DIN 41524 connector"). In consumer electronics, "DIN connectors" usually represent a member of the circular connector family specified by DIN. DIN connectors were originally used for the transmission of analog audio signals. Some of these connectors were later used for analog video and digital interfaces, such as MIDI or IBM PS / 2 interface keyboard and mouse cables. The original DIN connector standard has been replaced by the equivalent international standard IEC60130-9.

DIN connectors are made of

The DIN connector males are all 13.2 mm diameter metal shielded plugs, but their pin definitions are different.

The connector plug has a round metal shield skirt to protect the pins. The protective skirt also ensures that the plug is inserted in the correct direction to prevent damage to the pins. Due to the same protective skirt, it is not possible to prevent the DIN male connector from connecting to an incompatible DIN female connector. This design was modified in mini DIN.

DIN connectors have 7 common modes, and up to 8-pin connectors can be seen. There is limited compatibility in different standard connectors.

The screw-locked version of this connector is also used in instrumentation, process control and professional audio. ^[1]
