ABSTRACT:
An angular position sensor for determining the angular position of a shaft relative to a fixed support to which the shaft is rotatably connected, including a pair of interactive sensor elements respectively on the shaft and on the support, the elements being arranged for cooperation so that an electrical characteristic of at least one of the elements varies in accordance with the relative rotational positions of the elements, the cooperation being between two corresponding axially directed surfaces, one on each of the elements, a rigid spacer between and engaged upon the surfaces, and another member for permitting motion of one element along the axis of the shaft, for preventing motion of that one element in other directions than along the axis, and for applying a biasing force tending to press the elements toward each other against the corresponding surfaces of the spacer, for contact, whereby the spacing between the surfaces is kept constant by the spacer.
