Make one!
Neutrik make a metal bodied, locking jack line socket* the only one worth a light. The cable can be anything 3 core and up. You could use BBY/G mains cable but it ain't really proper for non-mains applications. 2, 3, 4 pair alarm cables is very good as is 4pr UTP network patch cable. You can of course use "balanced" mic cable but it is more expensive.
*Personally I would just put a jack in wee tin in fact you can have two or three.
If you are a soldering klutz Google for Rob at Kabl cable.
