Abstract

A sensor assembly includes a magnetic element operable to generate a magnetic field, a position sensor having a first sensor element operable to detect the magnetic field and a second sensor element placed at an angle with respect to the first sensor element and operable to detect the magnetic field, the first sensor element and the second sensor element each operable to generate a signal related to the magnetic field, and a processor operable to receive the signals from the first sensor element and the second sensor element to determine an angular position relating the magnetic element and the position based on the signals generated by the first sensor element and the second sensor element.
