The invention relates to a sensor which measures the angle of rotation or rotational speed and which comprises a pulse generator that is situated on a rotational element (10). Said pulse generator has a ring magnet (11) which is fabricated as an injection molded part and has a metal bushing (12) which holds said magnet ring (11) with positive fit. In order to provide a rigid connection which is provided between the ring magnet (11) and the rotational element (10) and which is favorable with regard to production techniques, the invention provides that the ring magnet (11) is held with a first ring section (111) on the bushing (12) and is fitted to the rotational element (10) with a first ring section (112) by using press fit. The bushing (12) is fastened to the rotational element (10) in the area of a bushing section (121) which projects from the ring magnet (11) on the front side, and the positive locking between the bushing (12) and the first ring section (111) is produced by mold elements on the outer circumference of the bushing (12) on which the ring magnet (11) is sprayed.
