Abstract
Abstract An arrangement for producing electrical signals by way of semiconductor elements which are dependent upon a magnetic field employs at least two field plates which are arranged adjacent to each other on at least one pole of a magnet. An iron part can be moved over the field plates whose width is selected in such a way and which is guided with respect to the field plates in such a way that when the iron part completely covers one field plate the other plate is not covered. The field plates are magnetic field dependent two pole elements having an electrical resistance characteristic which changes as a function of an applied magnetic field so that electrical signals are generated in response to field change when the field plates are connected in an electrical circuit.

Claim 1
Independent Claim
170 words
An arrangement for producing electrical signals by way of semiconductor component elements which are dependent upon a magnetic field, comprising: a magent having a pair of poles, a pole piece on one of said poles, a pair of magnetic field dependent semiconductor component elements arranged next to each other and spaced apart upon said pole piece, an iron member movable over said component elements, said iron member having a projection width onto the longitudinal plane of the magnetic field dependent elements which is at least equivalent to the length of the diagonal of a magnetic field dependent element, said iron member being inclined with respect to said magnetic field dependent component elements in its longitudinal direction with respect to the longitudinal direction of said elements lying at an angle which is sufficient to provide complete coverage of one of said elements while the other of said elements remains uncovered, the longitudinal plane of the magnetic field dependent component elements positioned parallel to the plane of motion of said iron part.
Claim 2
Dependent Claim
