Armature for an electromagnetic actuator with a sintered armature plate

An armature for an electromagnetic actuator, having a guide pin that is connected to an armature plate, characterized in that the armature plate (3) is formed by a frame element (4) that comprises soft-magnetic iron and is connected to the guide pin (2), and at least one plate element (5) that comprises a soft-magnetic material and is held in the frame element (4), the frame element has a transverse bridge connected at its ends to an edge frame, and the transverse bridge (4.1) and/or the edge frame (4.2) has or have projections or depressions (7) on the inside surfaces for creating a form-fit for the plate element (5).
