Recommended 4 pin plug/socket type etc

[glynster]

Hi, I am planning my electronics enclosure for my first CNC router. I want to interface to the electronics enclosure with some kind of plug and socket so that I can easily move the router and electronics box independently or replace machine cables should they get snagged etc.

I will have 3 axis and so 3 motor control cables each with 4 pins (would that be that 5 with the screening connected to earth?). I would ideally like the sockets to be panel mounted on the front of my enclosure. Do you think 4 pin DIN would suffice? Can they handle the current OK? I dont know of any other 4 or 5 pin panel mounted jacks and sockets.

Also, what kind of interface should I have for the limit switch cables? Would you include the BOB in the enclosure and have a parallel port socket on the enclosure too? Like I say, first build, not sure what the done thing is.

Muchos Gracias
