Tastelement für die Steuerung von Elektromotoren, insbesondere für Krane und andere Fördermittel

摘要

The sensing element has a sensing pin which is displaceable within a housing and which triggers a control signal. An electronic circuit (3) contains a permanent magnet (4) which can be adjusted w.r.t. a Hall sensor (5) and is integrated into the sensing element housing. (2) The permanent magnet is attached to the sensing pin and can be axially moved towards and away from the Hall sensor in unipolar manner. The permanent magnet can be adjustably mounted on the sensing pin.
