Abstract

The invention relates to a sensor device for measuring the rotational position of a rotating component, comprising a ring-shaped transducer magnet, wherein enclosing the transducer magnet are two flux conducting elements, of which at least one first flux conducting element comprises at least one flux conducting claw which extends axially at the outer circumference of the transducer magnet, the free end face of said claw lying at a distance to the second flux conducting element.
