ABSTRACT:
A position sensor which is particularly suitable for the rotational angle detection of throttle or exhaust gas valves comprises a permanent magnet and at least two magnetic field sensors arranged adjacently to the permanent magnet. The magnetic field sensors are, for example, Hall sensors. By a relative movement between the permanent magnet and the magnetic field sensors, a position-dependent signal, for example in dependence on a rotational angle of the shaft, is produced. According to the invention, the two magnetic field sensors are arranged behind each other in field direction of the permanent magnet.
