I’m looking for a 5 pin connector type that I can easily find chassis plugs for both male and female.
I’ve looked at DIN and mini xlr connectors, but have unsurprisingly been unable to find male chassis sockets.
The pins needs to support 12V 10A*
*realistically only expects about 6-7A flowing through 1 pin and one fourth of that through the 4 others.
Sorry, my original comment was poorly written. While they do lead to earth, there is a mosfet in between each that receives a unique PWM signal. See the edit for more details.
You could use something like a dsub connector with larger current carrying pins (more expensive) or a more regular connector (e.g. 15 pin dsub) with multiple pins for supply/high current.
Regular rectangular headers can handle anywhere from 1-5A per pin depending on the connector so you might be able to get away with a 2x4 rectangular header (maybe a few more pins in parallel for everything just for insurance)
