Abstract

A method for detecting the motion of an element relative to a sensor arrangement is proposed, wherein switching signals () are evaluated as a function of a pulse transmitter passing in front of the sensor, and a switching hysteresis (H) is adapted in the evaluation as a function of the values of the switching signal (). When the element moves below a predetermined limiting value (f), a relatively great switching hysteresis (Hyst) is set, and when the limiting value (f) is exceeded, a reduced switching hysteresis (H) is set.
