The mini-DIN connectors are a family of multi-pin Electrical connectors used in a variety of applications. Mini-DIN is similar to larger, older DIN connector. Both are standards of the Deutsches Institut für Normung, the German standards body.

Connector

---

Mini-DIN connectors are 9.5 mm in diameter and come in seven patterns with any number of pins from three to nine. Each "flavor" is keyed in such a way that a plug with one pattern cannot be mated with any plug of another pattern. (However, some out-of-spec plugs and sockets can intermate with standard versions—for example, the Apple GeoPort was a Mini-DIN 8 socket with an additional pin, and was thus able to accept GeoPort 9-pin plugs as well as the standard 8-pin Macintosh serial connector).

Applications

---

Mini-DIN connectors have found a use in many different applications, most often for audio/visual signals, computer data, or low-voltage DC power.

• Apple Desktop Bus (Mini-DIN 4)
• S-Video (Mini-DIN 4)
• PS/2 keyboard/mouse connector (Mini-DIN 6)
• Macintosh Serial Port (Mini-DIN 8)
• Apple GeoPort (modified Mini-DIN 8 with an additional pin)
• DC connector
• Sega Mega Drive II (Mini-DIN 9)
• Sega Saturn (Mini-DIN 10, non-standard)
