摘要： An electromagnetic actuating apparatus, in particular a proportional magnet or switching magnet, comprising a magnet armature (4), which is guided in axially movable fashion in a pole tube (2), which is at least partially surrounded by a coil winding and which is adjoined by a pole core (10) via a separating region (20) forming a magnetic decoupling, wherein, on energization of the coil winding (52), a magnetic force acts on the armature (4), which magnetic force attempts to move said armature (4) in the direction of the pole core (10) within a travel area, characterized in that at least one insert (28) consisting of ferromagnetic material with a preset axial thickness can be introduced between the armature (4) and the pole core (10) in order to shorten, as desired, the axial length of the travel area.

摘要： The invention relates to a displacement sensor system for solenoid coils (10) comprising at least two coil windings (14, 16) arranged in line on a main coil body (12). Since the coil windings (14, 16) form a primary winding (18) and an additional coil winding (24) is arranged on top to each coil winding (14, 16) of the primary winding (18) to form two secondary windings (20, 22), a displacement sensor system is configured in such a way that it can be produced in an economical manner and with a reduced length.
