Abstract (en)
[origin: WO9743603A1] A contactless position sensor including a Hall-effect cell (10) and a magnetic circuit consisting of a permanent magnet (18) and two pole pieces (20, 22). The magnet (18) and the cell (10) are arranged side by side between the pole pieces (20, 22), and said pole pieces comprise active surfaces (32, 34) at the opposite end from the cell relative to the magnet. This arrangement directly produces an output signal (Va-Vb) proportional to the distance (e) between the active surfaces (32, 34) and the target (38).
