Abstract
A torque sensor mounted on a rotating element in a motor vehicle, including at least one strain gauge and emitting an electrical signal as a function of the torsion experienced by the rotating element, the torque sensor having a moving part intended to be driven in rotation with the rotating element and including the strain gauge and a fixed part including a first printed circuit board. The torque sensor also acts as an angular-position sensor, the moving part bearing angularly distributed targets passing in succession past a first annular sector borne by the first board including a secondary receiver winding generating a sine signal, a secondary receiver winding generating a cosine signal, and a primary emitter winding inducing a voltage in the receiver windings.
