Abstract
In a rotation angle or rpm sensor having a pulse transducer seated on a rotation element, which has a ring magnet made as an injection molded part and a metal bush that receives the ring magnet by positive engagement, for the sake of a rigid connection between the ring magnet and rotation element, which is favorable from a production standpoint, the ring magnet is received with a first annular portion on the bush and with a second annular portion is seated with a press fit on the rotation element. The bush is fastened to the rotation element in the region of a bush portion that protrudes from the face end of the ring magnet, and the positive engagement between the bush and the first annular portion is made by shaped elements on the outer circumference of the bush, onto which the ring magnet is extruded.
