Abstract

The plate cam device has a plate (1) of soft magnetic material, with suitable geometric circumferential shape also arranged eccentric in relation to an axis of rotation (5) of the plate. Two or four magnetic flux sensitive semiconductors (4) are arranged at the circumference of the rotating plate to produce one or two sine/cosine signals. Two or four magnetic flux sensitive semiconductors (4) with magnet systems are arranged at an angle (phi) of 45 or 90 degrees at the working periphery of the plate, for a scanning which can also be carried out in a push or pull method.
