The indicator uses a magnetic field sensor (5) attached to one of 2 relatively movable parts (1, 2) and at least one cooperating indicator (6,6') attached to the other part, positioned so that the indicator moves past the magnetic field sensor during the relative displacement. The sensor has at least 2 magnetic field sensor elements (7, 7') lying adjacent one another along a line (8) which is perpendicular to the relative displacement direction (18) of the moving parts. Pref. semiconductor field sensor elements ae used, e.g. Hall elements. |
