Recommended 4 pin plug/socket type etc

[cropwell]

A lot of people use these ;_ http://www.audiospares.com/home.php?cat=1025
They are relatively cheap and rated up to 60v (I think). If you use the 4 pin for steppers and something else for homes, limits, probe and Estop then you can't plug the wrong thing in to the wrong socket.
