Teradek 4-Pin to P-Tap Cable, 18 in

Teradek cuts its cables for a named connector and a named length rather than shipping one generic run, and this is the lead for Teradek hardware with a 4-pin connector. The length matters more than it sounds: too long and there is a loop to dress on a moving camera, too short and the connector takes the strain every time the rig moves.

It is Teradek part number 11-0118. Teradek stocks it as an individual part, so it can be replaced on its own.
