Abstract

Capteur de position inductif comportant, d'une part, une bobine primaire (2) et, d'autre part, au moins une bobine secondaire (3, 5) qui comporte au moins deux bobinages secondaires constitués chacun de plusieurs spires réalisées sur deux couches d'une carte de circuit imprimé. Chacune desdites spires présente une première partie globalement concave disposée sur une couche de la carte de circuit imprimé et une seconde partie globalement concave disposée sur une autre couche de la carte de circuit imprimé. Parmi les premières parties (12) et deuxième parties (14) des spires des deux bobinages secondaires, au moins certaines de ces premières et deuxièmes parties sont agencées selon une symétrie miroir de part et d’autre d’un plan de séparation transversal, ce plan de séparation transversal (étant situé entre les deux bobinages secondaires et étant orthogonal à la direction longitudinale.
