An inductor sensor assembly for determining to position of object includes a layer of ferrite overlaying exciting and receiving coils formed on a substrate. A magnet attached to the target produces a virtual coupler in an area of ferrite overlaying the coils. An application for a shock absorber includes a sensor module mounted in a recess in a dust cover and a magnet mounted to a cylinder tube of the shock absorber. L'invention concerne un ensemble capteur inductif servant à déterminer l'emplacement d'un objet et comprenant une couche de ferrite recouvrant des bobines d'excitation et de réception formées sur un substrat. Un aimant fixé sur la cible produit un coupleur virtuel dans une zone de ferrite recouvrant les bobines. Une application pour un amortisseur comprend un module de capteur monté dans un renfoncement formé dans un couvercle anti-poussière, ainsi qu'un aimant monté sur un tube cylindrique de l'amortisseur.
