ABSTRACT:
A rotational position sensor, or angular position sensor, that having two pole pieces. Each of the pole pieces has a first end portion and a second end portion. The two second end portions are arranged in overlapping parallel association to provide a gap between them. Two magnetically sensitive components are disposed in the gap between the second end portions of the two pole pieces. The two magnetically sensitive components are used to provide redundancy in the event that one of the magnetically sensitive components experiences a failure.
