<p>The contactor (1) has a fixed armature with an enclosure (11) for housing a coil (2). The enclosure has a cover (13) for closing an opening of the enclosure and a movable armature (20) i.e. core, passing via an aperture of the cover. A guide ring made of non-magnetic material is arranged in the aperture so as to have, between a wall in contact with a wall of the aperture and another wall facing the movable armature, a thickness corresponding to a minimal radial gap between the armatures. The cover has a collar (18) delimiting the aperture and extending toward an interior of the enclosure.</p> |
