I'm looking for circular connector with size of mini din with so many pins as possible. I'm building embeddable controller for Roomba vacuum cleaner robot, and I want to led as many pins as possible from microcontroller through this connector.

The maximum pin number you can have on standard mini din connector is 9.

9 pin mini din connector

However, according to Wikipedia there are mini din connectors with more pins.


HR12-14R-20SDL from Hirose connectors have 20 contacts in a mini din size.
