Signal Transformer / Bel WRSC Circular Wireless Charging Coils are receiving rectangular wireless charging transmission coils, available in single windings. The WRSC series allows wireless transmission of power through inductive coupling to charge a number of products. These transmitter coils also use inductive coupling to transfer signals and data from one source to another. The Signal Transformer / Bel WRSC Circular Wireless Charging Coils’ use of inductive coupling eliminates conductive connections and traditional wiring, seamlessly transferring data and power while avoiding mechanical abrasion, corrosion, and wear. The fixed-in position inductive coils are non-moving, resistant to vibration and corrosion, and designed for reliability and longevity.
