Two models of power transfer hinges, to provide discreet transfer of power/signalling between a door and the frame. The C5P provides 5 contacts. Each contact is spring loaded to ensure a �connection� is achieved each time the contacts close. The contacts operate up to 1.5A (resistive & inductive load) at 12V, and are ideal for use on swing or sliding doors to provide power/control for electric locks, solenoids etc.
