Abstract
A sensor device having at least one sensor element, such as a Hall sensor element, and at least one magnet element that can move in relation to the sensor element. The sensor element has a number of differently magnetized regions. The sensor element is configured to issue a sensor signal, which represents a condition defined by a magnetization of a region of the magnet element located in the measurement range of the sensor element. The sensor element determines the condition by means of one of at least three pre-defined sensor signal values.
