Mini-DIN plugs have an outer diameter of 9.5 mm or the metal collar of 7 mm and come in seven different versions with different numbers of pins. The variants differ in such a way that the various plugs and sockets cannot be interchanged, which prevents potential damage. There are also sockets outside the standard that are pin-compatible with the standard versions of the plugs. One example is the GeoPort of Apple, the mini DIN-8 connector corresponds to a with an additional pin and both the GeoPort 9-pin connector and the 8-pin standard connector for the serial interface of the Macintosh can accommodate .

The pin numbers can usually be found stamped on the plastic part in which the pins are located, right next to them. The use of a magnifying glass may be necessary.

	Mini-DIN 3	LocalTalk - AppleTalk Personal Network
	Mini-DIN 4	Apple Desktop Bus S-Video (also known as Hosiden connector) The numbering can be seen when looking at the socket from the outside
	Mini-DIN 5	MIDI (but rarely), some manufacturers of external hard drives for the power supply used
	Mini-DIN 6	PS / 2 keyboard / mouse connector FDDI control signal for switching the optical bypass TNC transceiver connection with packet radio The numbering can be seen when looking at the socket from the outside
	Mini-DIN 7	Concealed serial control and maintenance port Roomba - Vacuum cleaner robots , z. B. used for coupling with house control
	Mini-DIN 7 non-standard	Combined connection for S-video and (via adapter) composite video for graphics and frame grabber cards Socket can accept 4-pin plug. The numbering is presumably evident when looking at the socket from the outside
