Abstract
The angular position sensor is for assembly on a rotating shaft rotationally guided in a support structure, and includes an annular member having an inner surface socketed on the rotating shaft without relative rotation therebetween, and a housing in which a permanent magnet is inserted. A support is provided having a through hole through which the rotating shaft and the annular member extend, the through hole having an inner surface opposite and close to the annular member with a radial allowance, a cavity housing a sensor device capable of detecting variations in the magnetic field caused by the permanent magnet upon rotating with respect to the support together with the annular member, and an anchoring configuration by which the support is secured to a fixed structure.
