摘要： The invention relates to a sensor (1) for detecting a linear or rotative displacement of an object. According to the invention, a sensor element (2) can be fastened to the object or forms part of the object, said element interacting with at least one detection element (3). The sensor is characterised in that two detection elements (6, 7) are located on one displacement plane adjacent to a magnet (4) that generates a magnetic field and that the sensor element (2) consists of a material that influences the magnetic field.

摘要： The invention relates to a sensor array (1) for measuring linear or rotational movements of a part. Said sensor array (1) comprises a magnet (2) and a magneto-sensitive element (3) that is disposed in a magnetic flux-free zone of the magnet (2). According to the invention, the magnet (2) is designed as a closed ring, and one pole of the magnet (2) points outward while the other pole of the magnet (2) points inward. Furthermore, the magneto-sensitive element (3) is arranged in the center of the ring.
