Rotation angle-sensor arrangement for detecting rotatary movements of measuring object, has magnet with cross section that constantly changes in circumferential direction, and magneto-sensitive sensor arranged at front surface of magnet

摘要

The arrangement has a magnet (1) and a magneto-sensitive sensor (3) e.g. Hall sensor, where the magnet is embedded in a magnetic field generator (2) and formed in a circular manner. The magnet has a cross section, which constantly changes in a circumferential direction. The sensor is arranged at a front surface of the magnet, which points in a direction parallel to a rotation axis of the magnet. The field generator is formed as a separate component, and is made of plastic material.
