Mini-DIN connectors — DIN 45322

Mini-DIN is a family of multi-pin electrical connectors used in a variety of (domestic) applications, including audio, video and computer equipment. Like the older and larger DIN connector, it was endorsed by the Deutsches Inititut für Normung (DIN) — the German Standards Institute [1].

The diameter is 9.5 mm and there are 7 different layouts, with an increasing number of pins from 3 to 9. The pin layout and the rectangular key are different on each connector, so that a plug with one pattern does not mate with the socket of another pattern. The drawings on this page all show the layout of the (female) socket. The pins are numbered from right to left, from bottom to top, starting with pin 1 at the bottom right. The (male) plug is the horizontal mirror of this layout.

PS/2 keyboard
This 6-pin Mini-DIN connector was used with the keyboard of the IBM PS/2 personal computer. It uses the same data format as the older IBM PC/AT: 1 start bit, 8 data bits, 1 parity bit (odd) and 1 stop bit. The keyboard reset works via a command string.
