Abstract
An angular position sensor includes a moving element consisting of at least one essentially cylindrical permanent magnet turning about it axis, at least two magnetosensitive elements and at least one processing circuit furnishing a signal dependent on the absolute position of the moving element The magnetosensitive elements are located essentially at the same point and in that they measure the tangential component of the magnetic field and the radial and/or axial component of the magnetic field for furnishing 2 sinusoidal signals that are essentially 90° out of phase.
