With 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 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 such that it transfers the movement of the armature, and 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. Such type magnet arrangements of this type are preferably used for electrical position feedback in fluidic valves.
A magnet arrangement for an electromechanical drive, especially for a fluidic valve, with a cylindrical armature guided in a pole tube and with a magnetic coil enclosing the pole tube and with a displacement sensor which transforms the position of the armature into an electrical signal and has a fixed part and a movable part, in which arrangement one side of the armature is formed for transferring the movement of the armature and an other side of the armature is connected to the movable part of the displacement sensor, the pole tube being provided with a closure part on a side of the displacement sensor, wherein the fixed part (28a to 28c, 36;
