ABSTRACT:
A rotary position sensing system and method are disclosed, including a shaft comprising an offset mounting hole, and a magnet having a magnetic field that is magnetized across an axis of the magnet, wherein the magnet is mounted to the shaft at the offset mounting hole and oriented to the offset mounting hole. One or more Hall-effect sensing elements can also be located a fixed distance from the magnet to provide a linear output signal proportional to the magnetic field of the magnet and the angular position of the shaft, thereby providing an angular position measurement of a device mated to the shaft.
