摘要： In a displacement pick-up for detecting the displacement of an actuator driven by a rotating drive element, which has an indexing mechanism (11) with a first indexing wheel (13), driven by the drive element and having an indexing cam (19), and a rotatable second indexing wheel with encompassing teeth (20), and which also has a device (12) for detecting the rotary position of the second indexing wheel (15), for the sake of achieving high freedom from noise the teeth (20) on the second indexing wheel (15) and the indexing cam (19) meshing with them on the first indexing wheel (13) are embodied with large surface areas, and the two indexing wheels (13, 15) are magnetized in such a way that their respective immediately adjacent faces repel one another.
