DIN Connectors

From Left: Line Plug, Chassis Socket


Round, push-fit connectors available in 2-8, 13 & 14-pin versions, including 3 different 5-pin types, and 2 different 8-pin types. Line plugs, line sockets and panel mounting sockets are available. 3-8 pin types all have the same size shell, and some are interchangeable (e.g. a 3-pin plug will fit a 5-pin socket). A notch in the shell ensures the plug will only fit one way round. Most common is the 5-pin 'A' type, used for audio and computer keyboard connections.

Typical Applications

2-pin - loudspeaker connections

5-pin - audio line level input/output (e.g. 'tape'), keyboard (not PS/2)

8-pin - stage lighting control (6 channel 0-10V analogue)

13 & 14-pin - Atari computer equipment

Other applications requiring a low voltage mutipole connector

Mini versions of these connectors are also available - see here for data.

Pin Assignments

Note the odd pin numbering - designed so that the pin numbers stay the same regardless of the number of pins in the connector:

Connector Assembly Instructions

Line Plug / Socket:

Normally solder connections. Thread outer cover onto cable, solder wires to pins, then assembly 2 halves of shell around connections and close cable clamp with pliers. Slide the plastic cover over the shell - a tab on the metal shell holds it on (you will need to bend the tab in to remove the cover again). 2-pin plugs/sockets may have screw connections and a push-on cover.

Chassis Socket:

Normally solder connections. It may help to fix the socket to the panel first to hold it steady.
