Mini DIN Connectors
Description | Applications | Pin Assignments | Assembly Instructions

Miniature version of DIN connectors, available with 3 to 9 pins. Mainly used on computer mice and keyboards (PS/2), and video equipment (SVHS). The shape of the shell, and a plastic pin in the centre of the plug ensures it will only fit one way round. Most common is the 5 pin 'A' type, used for audio connections. Unlike full size DIN connectors, the location and numbering of the pins is not standard for all connectors in the series.
4-pin - SVHS video connections
6-pin - PS/2 keyboard and mouse connections
Other applications requiring a low voltage miniature mutipole connector
See here for details of full size DIN connectors.
PS/2 Keyboard and Mouse Connections (6-pin):
Pin 1: Data |

Note that although the mouse and keyboard have identical pin connections, the connections on the computer are not interchangeable.
See D Connectors for pin-outs of serial mice.
SVHS Video Connections (4-pin):

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.
