Device for detecting object movements and/or positions has coils at least partly enclosing magnetically conducting spring, joined together annular magnets that carry out additional movement superimposed on rotational movement

摘要

The device has coils (6) at least partly enclosing a spring (4) consisting of magnetically conducting material that moves reciprocally under the influence of a magnetic field because of the reluctance effect to cause a polarity change of the magnetic field in the coil resulting in voltage pulses. It has magnets in the form of annular magnets (1) joined together that carry out an additional movement superimposed on the rotational movement.
