ABSTRACT:
A path and/or position measuring device is provided, including a magnet and a sensor for detecting the magnetic field intensity. The magnet and/or the sensor cooperate with a movable element. The magnet is formed such that the magnetic field intensity varies along an axis of the magnet and is not constant. The relative movement between the sensor and the magnet is substantially in the direction of the axis of the magnet. The path and/or the position of the movable element can be determined based on the magnetic field intensity detected by the sensor.
