BNC
The BNC connectors and their coaxial cable offers quick connection and reliable signal transmission. It's perhaps one of the most common connection types around, often seen laboratories and industry alike.
BNC cables can be used for connecting devices together (output of one device to the input of the another), to carry data acquisition signals, hardware triggering and so on. Just mind the voltages are right because a 5V device will break if you try to give it 10V.
However, BNC cables are not suited for power transfer, although admittedly they probably can do small <1A currents.
We make BNC cables to many different lengths. We also sell the cable and the connectors separately if you would like to make your own cables.
