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.
