ABSTRACT:
A detector for detecting movements which, in its simplest form of embodiment, has one exciter magnet: (EM) and only one individual pulse wire (FE) with one induction coil (SP1) and with a sensor (SP2, HS) for determining polarity and position of the moveable exciter magnet (EM). All information is simultaneously determined at the time (Ts), that the ferromagnetic element (FE) is triggered and remagnetized by said magnet (EM). For counting operation a further information about the last established position and polarity of the exciter magnet is used, which is stored in a nonvolatile memory (36) of an associated evaluation circuit.
