Abstract

The solenoid is intended for providing a soft attraction movement, together with simple adjustment. The non-magnetic guide pin provides a longitudinally shiftable mounting of the armature in the pole piece of a magnetic body. The guide pin (8) has a lift limiting stop in the form of a safety disc (9). Between the pole piece (3) and the armture (6) is incorporated a compression spring. The pole piece is adjustable in relation to the magnetic body in the lifting direction of the armature. Preferably the end of the pole piece, facing the armature is in the form of a conical extension (4), while the armature end opposite the pole piece is fitted with a corresponding counter-cone (7). The pole piece may have an outer thread (3a) for centering and adjustment in the top surface (2) of the magnetic body. A coil core (12) may have a central guide (13) for the armature, into one end of which the pole piece penetrates without clearance.
