Planning building a telescope drive – 2 Nema17 motors off hand held home brew stepper drive box. Power source 12 volt (Lidl) battery so not a big shock hazard.

What connectors would be reasonably robust and not cost an arm&leg? One 4 wire cable to each motor.

I generally use XLR connectors:

RS probably not cheapest source.

I used these when building my rotary table stepper. Cheap, positive screw down ring & rubber plug for when disconnected.

If you’re quick, Arc have some 4 way chassis sockets for £1.94 each.
