Beschreibung
Zusammenfassung:	The invention relates to a device (20) for detecting the angular position of a pinion (15) of gear box drive device (15). The device (20) has a magnetic element (25) that is provided at the front end portion of the pinion (15) that is indirectly cooperated with driven gear (15), to detect magnetic field of a sensor unit (22). The pinion and the driven gear (15) in connecting region (26) with magnetic element (25) are made of plastic. The magnetically active particles of magnetic element (25) are bonded with each other through the injection molding process, dispersed in a plastic material and located on an end face of the pinion and driven gear (15).
