摘要： A telescopic actuator comprising a cylinder (2) in which a rod (3) is mounted to slide along a sliding axis (X), the actuator including a locking member comprising a locking finger (10) that is movable along a locking direction (Y) that is perpendicular to the sliding axis, between a locking position in which an end (9) of the locking finger (10) is engaged in a groove (8) of the rod in order to lock the rod in position, and a retracted position in which the end of the finger is disengaged from the groove in order to release the rod, a locking indicator (20) being secured to the locking finger to be movable between a position indicating locking when the locking finger is in the locking position, and a position indicating unlocking when the locking finger is in the retracted position, the actuator being characterized in that the locking indicator is secured to the locking finger by a connection (22, 23, 24) suitable for being interrupted in the event of the end of the finger being broken off while the rod is locked, a thrust spring (25) being arranged in the locking finger to push the locking indicator towards the position indicating unlocking when said connection is interrupted.

摘要： A bistable linear electromagnet comprising a first housing (10) and a second housing (11) in alignment, a movable armature (18) comprising a rod (19) and a shuttle (20) that is slidably mounted, and a first coil (13) positioned in the first housing and a second coil (15) positioned in the second housing. A cavity (25) is made in a measurement wall (4) of one of the housings, and the electromagnet comprises a magnetic field sensor (26) positioned in the cavity and designed to measure a magnetic flux existing in a magnetic path formed by the walls of said housing and by the shuttle, in order to detect whether the shuttle has moved towards or away from the abutment wall of said first or second housing.
