ABSTRACT:
For detecting the angle of rotation of a shaft, in particular of a gear shift shaft in a gear change box for a motor vehicle, a device is proposed in which a carrier arrangement carries a magnet and in its proximity magnetically sensitive sensors. A screening device, rigidly attached to the shaft, moves in the intermediate space between the magnet and the sensors. This screening device is made from a ferromagnetic material such that the magnetic field permeating the sensors is influenced in a manner whereby the sensors generate a signal that unambiguously identifies the position of the shaft.
