Device for determining the actual position of an actuator

摘要

Arrangement for determining the actual position of a drive member (3) along its stroke or angular path, comprises a permanent magnet (6) mounted on the drive member so that it can interact with means for detecting the position of the drive member. The detecting means comprise a potentiometer film element (5), whose contact electrode (7) is aligned parallel to the drive member. On the side of the film element opposing the magnet is a strengthening element (10) in the form of a ferromagnetic material containing plastic film.
