( ) Wireless Charging Coils Single Overview Signals Wireless Charging Coil (WCC) Series are wireless charging transmission coils, available in single, double and multiple windings congfi urations. The WCC Series allows power to be transmitted wirelessly through inductive coupling to charge an array of products. The WCC Series transmitter coils utilize inductive coupling to transfer signals, data and power from one source to another. Of its many applications, the most common include phones, tablets, gaming controllers, wearable devices, tooth- brushes, robotic cleaners, drones and many smart car charging applications. Model Shown: WTSC-10R0K-A3, The advantages of the WCCs use of inductive Top View 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. Model Shown: WTSC-24R0K-A10, Front View Features 1.
