In the case of a magnet arrangement for an electromechanical drive with a cylindrical armature guided in a pole tube, the position of the armature is transformed into an electrical signal. Provided for this purpose is a displacement sensor which is connected to the armature and has a fixed part and a movable part. One side of the armature is formed in such a way that it transfers the movement of the armature, the other side of the armature is connected to the movable part of the displacement sensor. The pole tube is provided with a closure part on the side of the displacement sensor. A pressure tube is led to the outside through an axial clearance of the closure part. The movable part of the displacement sensor moves in the pressure tube. The pressure tube is enclosed by the fixed part of the displacement sensor. In order to prevent the displacement sensor from being damaged by vibrations, the fixed part of the displacement sensor is arranged in a clearance of the closure part. Magnet arrangements of this type are preferably used for electrical position feedback in the case of fluidic valves.
