Abstract

L'invention concerne un capteur de position du type comportant un codeur formé par un anneau magnétique multipolaire (1) pourvu, sur sa circonférence, de pôles Nord et de pôles Sud alternés et monté pour défiler devant une cellule de mesure (2) au moins l'un desdits pôles d'un signe déterminé est dit 'irrégulier' et comporte notamment des moyens de correction de la valeur de son champ magnétique, de manière à stabiliser le signal magnétique délivré, par le passage des pôles voisins audit pôle irrégulier. Selon l'invention : ' la cellule de mesure (2) est sensible à la composante tangentielle du champ magnétique délivré par les pôles, ' les moyens de correction sont réalisés par une zone surfacique (4) du pôle irrégulier (Pi) entourée par un pôle de liaison (5) avec les pôles adjacents, de même signe que le pôles adjacents, les moyens de correction (3) étant réalisés de manière que le signal magnétique tangentiel, engendré entre le passage de chaque pôle adjacent audit pôle irrégulier, varie de façon monotone.
