Abstract
(DE) Die Erfindung betrifft eine Sensoreinrichtung (1) mit einem in einer Bewegungsrichtung verlagerbaren Geberelement (2) und mit mindestens zwei gehäusefesten magnetfeldsensitiven Sensoren (3) zur Bestimmung einer Position und/oder Bewegung des Geberelements (2), wobei das Geberelement (2) eine erste Magnetanordnung (6) aufweist, die entlang der Bewegungsrichtung des Geberelements (2) unterschiedlich ausgerichtete Magnetfelder aufweist. Es ist vorgesehen, dass das Geberelement (2) eine zweite Magnetanordnung (7) aufweist, die entlang der Bewegungsrichtung des Geberelements (2) unterschiedlich ausgerichtet Magnetfelder aufweist.
(EN) The invention relates to a sensor device (1) having an encoder element (2), which can be displaced in a direction of movement, and having at least two housing-affixed, magnetic field-sensitive sensors (3) for determining a position and/or movement of the encoder element (2), wherein the encoder element (2) has a first magnet arrangement (6), which has differently aligned magnetic fields along the direction of movement of the encoder element. According to the invention, the encoder element (2) has a second magnet arrangement (7), which has differently aligned magnetic fields along the direction of movement of the encoder element (2).
(FR) L’invention concerne un dispositif de détection (1) comprenant un élément émetteur (2) mobile dans une direction de déplacement et au moins deux capteurs (3) sensibles à un champ magnétique et solidaires du boîtier, et servant à déterminer une position et/ou un déplacement de l’élément émetteur (2), l’élément émetteur (2) comprenant un premier système magnétique (6) qui présente des champs magnétiques orientés différemment dans la direction de déplacement de l’élément émetteur (2). Selon l’invention, l’élément émetteur (2) présente un second système magnétique (7) qui présente des champs magnétiques orientés différemment dans la direction de déplacement de l’élément émetteur (2).
