Abstract
A sensor for measurement of shaft angle values of a rotatable magnetized shaft employs a plurality of bridge circuits with corresponding magnetoresistive sensing elements disposed spaced-apart from a magnet disposed in an end of the shaft. The bridge circuits are held by a base which includes a cavity for receipt of the end of the shaft having the magnet. A housing secures the shaft and positions the shaft for rotation within the cavity. The base is formed of polybutalene teraphthallate which is permeable to magnetic lines of force, thereby permitting a coupling of the magnetic field of the shaft to the magnetoresistive sensors for measurement of an angle of the shaft about the shaft axis.
