Abstract
The invention relates to a position and/or speed sensor including a mobile target () with at least one tooth, a first permanent magnet (), at least one second permanent magnet (), and a probe () sensitive to the direction and intensity of a magnetic induction, and placed along an axis OZ such that when there is no adjacent tooth, the magnetic induction created by the first magnet passes through the probe along a direction opposite to the direction of magnetization. Magnetic inductions created by the permanent magnets () have approximately equal values but in opposite directions, and in the presence of an adjacent tooth, the absolute value of the variation of the magnetic induction detected by the probe () is greater than a trip threshold.
