Abstract

Codeur pour capteur de position, du type comportant un anneau magnétique multipolaire (2) pourvu, sur sa circonférence, de pôles avec des polarités de signes opposés, le codeur comportant au moins une zone de marquage (Pi) présentant une largeur angulaire (Li) supérieure à la largeur angulaire de chacun des pôles alternés situés hors de cette zone sur la circonférence de l'anneau, caractérisé en ce que ladite zone de marquage (Pi) comporte deux pôles singuliers (Ni, Si) jointifs présentant des polarités de signes opposés disposés dans la continuité d'alternance de pôles de l'anneau (2) et dont la largeur angulaire est supérieure à celle des pôles situés hors de la zone de marquage, l'aimantation au sein des pôles singuliers évoluant graduellement de façon continue entre les deux d'extrémités de la zone de marquage.
