ABSTRACT:
A sensor for measuring the speed and/or position of a piston in relation to that of the cylinder it moves inside of in a dashpot of shock absorber for motor vehicles. The sensor consists of a permanent magnet (10) connected to the cylinder (1) and of a sensor winding (9) in the form of a cylindrical coil that operates in conjunction with the magnet. The sensor winding has leads at the ends. Additional leads for a shorter winding component (7 and 8) extend out separately upstream of the ends of the sensor winding.
