ABSTRACT:
A target wheel sensor assembly includes a target wheel, a magnet, and two or more sensing elements placed therebetween. The magnet and the sensing elements are configured so that as the target wheel rotates each of the sensing elements outputs a respective asymmetric signal relative to the direction of rotation of the target wheel or an object mechanically connected to the wheel. Each of these asymmetric signals is differentially combined with one another to determine the direction of motion of the target wheel, and, if optionally desired, the position of the target wheel.
