HALL EFFECT LINEAR POSITION SENSOR FOR MOTOR VEHICLE

摘要

The invention concerns a Hall effect linear position sensor for a motor vehicle, in particular for a clutch master cylinder for a motor vehicle, comprising a piston (20) movable in translation in relation to a fixed part of the position sensor, either the piston (20) or the fixed part comprising a magnet (22) with diametrical magnetization received in a housing (24), and either the piston (20) or the fixed part comprising a magnetic field detection circuit, the magnet (22) and the housing (24) being shaped so as to enable the insertion of the magnet (22) in the housing (24) only in the angular positions of the magnet in which, when the magnet (22) is axially level with the detection circuit, the direction of the magnet (22) at the detection circuit is substantially parallel to the direction of the field lines in the magnet (22).
