Abstract:
A position sensor, designed, in particular, for detecting torsion in a steering column, includes a first magnetized magnetic rotor structure comprising a plurality of magnets, two flux-collecting components, which define at least one air gap in which at least one magnetically sensitive element is positioned. Each collecting component has at least one primary collecting zone extended by at least one extension having at least one secondary collecting zone. The secondary collecting zones end in flattened shoes that form the two poles of the air gap. The transverse mid-plane of the air gap intersects at least one of the extensions.
