Abstract
The invention concerns a position sensor, designed in particular for detecting a steering column torsion, consisting of a first magnetic structure including a plurality of magnets and a second magnetic structure including two ferromagnetic rings () having a plurality of teeth () and defining an air gap wherein is placed at least a magneto-sensitive element (), the two magnetic structures being respectively integral with two parts in relative rotation. The invention is characterised in that the two ferromagnetic rings () are nested and have each a substantially tubular part forming axially oriented teeth () connected by a flux-closing zone (), the detecting air gap being delimited by said flux-closing zones.
