I don't have much to give, but I was looking for a cable connector capable of transmitting a digital signal both ways in order to interface with a microcontroller. It's going to be attached to a moving object. It has to disconnect, and I though I remembered a connector that either locked to the socket, or had a screw type connector. Banana sockets are not quite right, as I want the male end to have a connector for easy deattachment/reattachment.
Thanks
