Hall sensor arrangement and use of the Hall sensor array in a buckle

Hall sensor array for detecting the positional change of two relative to each other in two end positions of movable members with a Hall sensor (71) with at least one Hall measurement field (H; H1, H2) and a field magnet (72), characterized in that an actuator (74; 85; 805 ) (for the transmission of the change in position of the two relatively movable components to the Hall sensor 71) is provided, and the Hall sensor (71) and the exciter magnet (72) are so combined to form a pre-assembled structural unit that, for a relative change in position of the exciter magnet (72 ) (for the Hall sensor 71) the polarity of the (in the Hall measurement field H from one end position to the other end position; H1, H2) the applied magnetic field is altered, preferably reversed.
