Abstract

L'invention concerne un capteur magnétique pour déterminer la position d'un mobile (2), le capteur comportant : - un système (4) de transformation du mouvement du mobile (2) en un mouvement de rotation avec un angle de rotation (A) qui est une fonction en arcsinus de la position linéaire (P) du mobile. - et un aimant (11) possédant une induction magnétique selon une direction donnée et au moins une cellule (13) de mesure montée pour être sensible à la direction de l'induction magnétique créée par l'aimant (11), la cellule (13) ou l'aimant (11) étant fixe tandis que respectivement l'aimant (11) ou la cellule (13) est guidé en rotation selon un axe de rotation (X) et entraîné en rotation autour de l'axe par le système de transformation de mouvement (4).
