Abstract
A wheel speed sensor comprises a Hall device disposed in a pocket in a cavity of a plastic housing. The cavity is filled with potting compound to capture and enclose the Hall device. Flux issued from a magnet that rotates with the wheel acts upon the Hall device and is concentrated on the Hall device by ferromagnetic fragments interspersed throughout the potting compound.
