ABSTRACT:
A speed sensor for a vehicle wheel having a rotating tone wheel and a stationary magnetic sensor with a sensing pole proximate the tone wheel teeth and a compensating pole proximate the tone wheel spaced from the tone wheel teeth. The sensing pole and compensating pole are secured to the ends of a permanent magnet in U-shaped configuration and coils connected in series opposition are wound on the sensing and compensating poles. Noise components generated in the sensing coil with the speed signal voltage due to axial misalignment and vibration of the tone wheel are cancelled by corresponding noise components generated in the compensating coil to provide a substantially noise free signal voltage corresponding to wheel speed.
