Abstract: A Hall-effect sensor assembly (1) for measuring linear movements and a Hall-effect sensor (3) as well as at least one magnet (4) that moves relative to the Hall-effect sensor (3) or vice versa, where according to the invention two magnets (4 and 5) are provided at a predetermined spacing and between the magnets (4 and 5) there is a spacer (6) of magnetically conductive material.

Abstract: A sensor system for measuring angular movements of measurement objects with at least one magnet (1) and a magneto-sensitive sensor (3), where according to the invention the magnet (1) is imbedded in a magnet support (2) and is circularly arcuate, and the magnet (1) has a cross section that varies angularly.

Abstract: 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.
