Abstract

La présente invention a trait à un capteur de verrou, à utiliser dans un actionneur, tel que ceux utilisés dans les trains d'atterrissage d'avion. Le capteur de verrou comprend au moins un dispositif émetteur de champ (46) fixé sur une cuve de pression d'un actionneur de blocage ; le dispositif émetteur de champ (46) surveille la position d'au moins une cible (48). Le dispositif émetteur de champ (46) émet un champ qui, lorsqu'il est rompu par la cible, envoie un signal pour indiquer que l'actionneur est verrouillé.
