Abstract

L'invention concerne un capteur de position ou de déplacement, comprenant un circuit de détection et un curseur (2) dont le circuit de détection détecte la position, ce curseur (2) comprenant un support (20) constitué d'un matériau inerte pour le circuit de détection, et un organe d'influence (21) porté par le support (20) et comprenant un matériau actif pour le circuit de détection. Selon l'invention, l'organe d'influence (21) est réalisé sous forme de particules (P) du matériau actif noyées dans une masse (M) du matériau inerte. Application à la mesure du déplacement ou de la position d'un piston de système de freinage pour véhicule à moteur.
