Abstract

A sensor device includes an encoder element and at least two housing-affixed, magnetic field-sensitive sensors. The encoder element can be displaced in a direction of movement. The sensors are configured to determine a position and/or movement of the encoder element. The encoder element has a first magnet arrangement, which has differently aligned magnetic fields along the direction of movement of the encoder element, and a second magnet arrangement, which has differently aligned magnetic fields along the direction of movement of the encoder element.
