Teradek 2-Pin to XLR Power 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 2-pin power input. 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 11-0319. Teradek stocks it as an individual part, so it can be replaced on its own.
