The invention relates to an analog non-contact distance sensor which includes a fixed stationary annular magnetized armature. The stationary armature member is provided with an air gap into which is disposed an element which is sensitive to a magnetic field. The moving portion is a rod-shaped magnetic core member which can be inserted into the annular armature member. Depending on the depth of insertion of the core member, the amount of diversion of the magnetic field from the air gap of the armature is controlled. Consequently, the magnetic sensing element emits an electrical signal which corresponds to the distance travelled by the movable core member.

The invention relates to an electropneumatic coupling arrangement for providing a pressure-tight connection between a pressure supply line and a pressure chamber of a hydropneumatic component. The coupler includes a plastic plug-in body member having a pressure conduit and a plurality of electrical contacts for interconnecting an electrical sensing element located in the housing of the hydropneumatic component to apparatus located outside the hydropneumatic component.
