摘要:
The invention relates to a device for detecting movements and/or positions of an object with the aid of voltage pulses induced by the field of adjacent magnets (6, 7) in a coil (4). In order to generate a sufficiently strong signal also at small relative speeds between the magnets (6, 7) and the coil (4), the coil (4) encloses a spring (5) in which a quick fore-and-aft movement can be induced by the magnetic fields of the magnets (6, 7), the magnetic poles of the spring (5) being reversed during said fore-and-aft movement.
