Pole head for powered warehouse vehicle has Hall sensor for controlling traveling movement of vehicle whose output signal is proportional to angle of rotation of drive switch handle and/or magnet carrier with two permanent magnets

摘要

The device contains a Hall sensor (18') for controlling traveling movement of the vehicle, whose output signal is proportional to the angle of rotation of the drive switch handle and/or a magnet carrier (20) with two permanent magnets (21,22). The Hall sensor is securely mounted so that faulty radial and axial movements transferred to the rotation shaft (14') of the magnet carrier do not cause drive signal errors. An independent claim is also included for a drive value generator for a measurement arrangement for generating control signals for propulsion drive control.
