摘要： The invention relates to an angular or linear magnetic position sensor that comprises a mobile member including at least one magnet (1) having a magnetisation direction that varies linearly along the movement direction of the magnet in a surface defined by said movement direction and in a normal direction, at least four magneto-sensitive elements (2, 3 and 4, 5) and at least one processing circuit (6) providing a signal based on the absolute position of the mobile member, characterised in that a first set of magneto-sensitive elements (2, 3) and (4, 5) are located at a same point, the first couple of magneto-sensitive elements (2, 3) being spatially offset from a second couple of magneto-sensitive elements (4, 5) along the movement direction, and in that the magneto-sensitive elements (3 and 5) measure the tangential component of the magnetic field while the magneto-sensitive elements (2 and 4) measure the normal component of the magnetic field in order to provide, after algebraic combination of the components taken in pairs, two sinusoidal signals substantially having an electrical phase shift of 90°.
