Audio DIN Connector Pinouts

A DIN connector is an electrical connector that was originally standardized by the Deutsches Institut für Normung(DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term “DIN connector” alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., “DIN 41524 connector”). Some DIN connector standards are:

  • DIN 41524, for circular connectors often used for audio signals
  • DIN 41612, rectangular connectors used to connect plug-in cards to a back plane or motherboard
  • DIN 41652 D-subminiature connectors used for computer data and video


The connector is 5 pin DIN male


The associated connector is 5 pin DIN female



The 5/180° connectors are commonly used for

  • SYNC interface for electronic musical instruments,
  • MIDI interfaces for electronic musical instruments,
  • Serial ports in the original Apple IIc personal computer,
  • In the original IBM PC, PC/XT and PC/AT, as well as the Amiga, for the computer keyboard cable (this connector fell out of use in the mid nineties as the ATXform factor used the PS/2 connector instead).
  • The original IBM PC also used this connector type for its cassette port—right next to the keyboard port using the same connector type.
  • Audio in the original HME wireless communicators, it is the headset connector for (Tx & Rx) Inbound and Outbound audio for Drive Through Restaurants
  • Controlling tilt of UMTS Antennas (Antenna Interface Standards Group)
  • Connecting two controllers for radio controlled model aircraft together for training purposes.
