| 摘要 |
The invention relates to a magnetic angular or linear sensor including at least one permanent magnet (1) defined in a cylindrical (r, Q & z) or Cartesian (x, y & z) coordinate system and at least two magneto-sensitive elements (2 and 3), in which the magnet (1) can move in relation to said two magneto-sensitive elements (2 and 3). The invention is characterised in that at least one dimension of the magnet (1) varies as a non-constant function and in that the magnetisation of the magnets (1) is oriented in a single direction, i.e. x, y or z in the case of a magnet defined in a Cartesian coordinate system or r, Q or z in the case of a magnet defined in a cylindrical coordinate system. |
