belfuse.com/signal WRSC Series Circular Wireless Charging Coils (Receiving) Signal’s Wireless Circular Charging Coil (WRSC) Series are receiving rectangular wireless charging transmission coils, available in single windings configuration. The WRSC Series allows power to be transmitted wirelessly through inductive coupling to charge an array of products. The WRSC Series transmitter coils utilize inductive coupling to transfer signals, data and power from one source to another. The advantages of the WRSC’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. General Features
