Have a question about this product?


SDC’s WPT uses a radio frequency (RF) transmitter to send energy wirelessly across the door gap to an RF receiver that converts the energy to DC voltage - to power electrified locks and latches. Retrofitting electrified locks into openings with existing wood doors is simpler and less time consuming – core drilling the door is not required. Works well with steel doors, too.

Plus, unlike competitive wireless power transfer devices that use magnetic induction for the power transfer, the WPT’s RF technology also allows for transfer of latchbolt monitoring, REX or data signals.

The WPT eliminates unsightly, exposed wires across the door gap that are susceptible to vandalism or breakage through use over time and includes a timed trigger to allow for up to 90 seconds of sustained voltage, if required. The WPT transfers power wirelessly across door gaps up to 7mm (a little over 1/4”), and provides more tolerance in lining up the transmitter and receiver vertically and horizontally than inductive power transfer devices.
