ABSTRACT:
Device for sensing angular position of a shaft utilizes a flat on the shaft, a permanent magnet with its polar axis perpendicular to the shaft axis, and a magneto-resistive element between the magnet and the flat. The resistance of the element varies linearly as the shaft is rotated from a first position to a second position.
