Abstract
A solenoid arrangement has at least one excitation coil and an armature arranged concentrically relative to the excitation coil and axially movable when the at least one excitation coil is supplied with current. A magnetizable cup-shaped housing part open at a first axial side is provided, wherein the at least one excitation coil is at least partially surrounded by the magnetizable cup-shaped housing part. A magnetizable yoke covers the first axial side for closing the magnetic circuit. A housing cover covering the solenoid arrangement is formed of plastic material, wherein the plastic material has at least one attachment flange for mounting the solenoid arrangement on other parts.
