Abstract

La présente invention a pour objet une roue dentée (1) d’arbre à cames, formant une cible pour un capteur de rotation d’arbre à cames, comprenant une pluralité de dents (10) réparties sur sa circonférence, la roue dentée comprenant un premier ensemble (13) de quatre dents espacées chacune de 90°, et un deuxième ensemble (14) de six dents espacées chacune de 60°, les dents de chaque ensemble étant réparties de sorte que la roue comprenne deux portions (16) de sa circonférence dépourvues de front actif de dents sur un angle d’au moins 35° et espacées de 180°, les dents du premier ensemble de dents et du deuxième ensemble de dents étant agencées de sorte qu’aucune dent ne soit commune au premier ensemble de dents et au deuxième ensemble de dents. Figure pour l’abrégé : Fig. 2
