An electromagnetic actuator is disclosed. The actuator has a coil arrangement which can be excited electrically, and has an armature. The armature is mounted such that it can move axially in the coil arrangement, is composed of soft magnetic material, and is moved in the axial direction when the coil arrangement is excited. A guide sleeve is fixed in the coil arrangement and guides the armature in the axial direction. The guide sleeve is produced from a soft magnetic material.
