Abstract
A target wheel sensor assembly includes a target wheel, a magnet, and a sensing element placed therebetween. The magnet and the sensing element are configured so that as the target wheel rotates the sensing element outputs an asymmetric signal. This asymmetric signal is used to determine the position of the target wheel as it rotates and the direction of motion of the target wheel.
