Abstract
A travel sensor for detecting an absolute value of a travel of a mechanical component or a travel change, the travel sensor has a rotatable circular sensor element having a circumference, a detector, and a mechanical device arranged so that a longitudinal motion of the mechanical component is convertable with the mechanical device into a rotary motion of the sensor element, the mechanical device being formed as a Bowden cable which is acted upon by the longitudinal motion of the mechanical component to be detected and is retained on the circumference of the circular sensor element so as to be wound up onto and wound from the circular sensor element, the sensor element carrying a dipole permanent magnet whose field lines as a function of its rotary position intersect the detector in different directions, so that in operation an unambiguous angle signal is present at an output of the detector.
