Abstract
An electromagnetic actuating apparatus, in particular a proportional magnet or switching magnet, includes a magnet armature () guided for axial movement in a pole tube (). The pole tube is at least partially surrounded by a coil winding and is adjoined by a pole core () via a separating region () forming a magnetic decoupling. On energization of the coil winding (), a magnetic force acts on the armature () to move the armature () in the direction of the pole core () within a travel area. At least one insert () of ferromagnetic material with a preset axial thickness is between the armature () and the pole core () to shorten, as desired, the axial length of the travel area.
