Listen Technologies LPT-A117 Remote Power Supply Kit

The LPT-A117 lets a single CAT-5e cable carry DC out to a ListenIR transmitter/radiator combo mounted away from the rack. One adapter converts the barrel jack to RJ-45 at the supply end, the other converts back at the device, and the run in between is ordinary structured cable.

It is the clean answer when the radiator wants to live on a wall or ceiling and there is no outlet nearby, but there is a spare pair in the conduit. The barrel fitting is a 5.5 mm OD centre-positive plug, and a 6 inch barrel-to-barrel jumper is included.
