A position sensing device (2) contains a magnetic field generating device (3) having at least one magnetic pole (4j) and a sensor device (5) with at least one sensor (6) with an enhanced magnetoresistive effect. The magnetic field generating device (3) should be arranged with respect to the sensor device (5) in such a way that the sensor (6) is laterally offset with respect to the magnetic pole (4j), and a central normal (Z n) to the pole face (F l) of the magnetic pole is at least approximately in the plane (E l) of a measurement layer (9) of the sensor (6) or in a plane parallel to it. In addition, the magnetic field generating device (3) should be movable so that the magnetic field (h) of the magnetic pole (4j) is detected by the measurement layer (9) of the sensor (6), and a run through all or part of the sensor characteristic curve is induced, with essentially only dependence on the direction of the magnetoresistive effect of the sensor being utilized.
