Wireless Charging Coils - WRSC/WRSR Series

Signal Transformer's wireless charging transmission coils are available in a single-winding configuration

Image of Signal Transformer's Circular Wireless Charging Coils - WRSC SeriesSignal Transformer's WRSC/WRSR series are circular or rectangular wireless charging transmission receiving coils available in a single-winding configuration. The WRSC/WRSR series allows power to be transmitted wirelessly through inductive coupling to charge an array of products. The WRSC/WRSR series transmitter coils utilize inductive coupling to transfer signals, data, and power from one source to another. The advantages of the WRSC/WRSR's use of inductive coupling eliminates conductive connections and traditional wiring, seamlessly transferring data and power while avoiding the mechanical abrasion, corrosion, and wearing-out of conductive contacts. The fixed-in position inductive coils are non-moving, resistant to vibration and corrosion, and are designed for reliability and longevity.
