Abstract: An angular position sensor is couplable to an actuator for angular positional sensing of a shaft thereof. The sensor includes a base for mounting to the actuator. A diametrically magnetized permanent magnet ring is coupled to, and axially aligned with, the shaft. Further, a magnetic material cylindrical sleeve is coupled to the said base and disposed circumferentially around the magnet ring such that the sleeve is separated from said magnet ring by an air gap. A pair of diametrically opposing cylindrical segments are coupled to the sleeve by a circular support member and extend through the magnet ring. The cylindrical segments having a slot between them in which a hall effect transducer is disposed. The transducer senses the magnetic field flux of the magnet ring in the slot and thereby produces a signal indicative of the shaft's angular position.
