  • Hall effect contactless position sensor providing a direct proportion between a hall effect voltage and a distance to a magnetic target
    Patent number: 6060880
    Abstract: A contactless position sensor includes a Hall effect cell and a magnetic circuit formed by a permanent magnet and two pole pieces. The magnet and the cell are juxtaposed between the pole pieces. The pole pieces have active surfaces opposite the cell with respect to the magnet. This layout makes it possible to directly obtain an output signal proportional to the distance separating the active surfaces from the target.
