ABSTRACT:
A rotatable clock disc of soft magnetic material has one or more teeth arranged in an asymmetrical graduation at the periphery for use as a pulse generator with a field plate differential sensing component. Each tooth is in the form of a flap formed by a pair of radially extending cuts spaced apart an interval greater than the width of the sensing component. The flap is bent so as to extend generally parallel to the plane of the disc and provides balance of the disc when rotated.
