Abstract
An angular position sensor includes a rotor attached to a shaft. A first magnet and a second magnet are attached to the surface of the rotor. Moreover, a first concentrator and a second concentrator are disposed around the perimeter of the rotor opposite each other. A space is established between the first concentrator and second concentrator, and a magnetic field sensing element is disposed in the space. As the rotor rotates with respect to the sensing element, the sensing element outputs a linear signal representing the location of the rotor with respect to the sensing element over a range between negative ninety degrees and positive ninety degrees.
