    Abstract: According to the invention, the coil of a magnet coil arrangement has a coil body which comprises a winding (14) and is extruded with plastic (17). A plug-in base with contact connectors is formed on the coil, wherein one of the connectors is used for connection of the grounding conductor (18). A metallic housing is placed over the coil. Connection of said metallic housing to the contact connector associated to the grounding conductor is achieved by means of a connection element which is guided through a recess of the plug-in base. A sealing element (42) disposed between the connection element and the recess prevents penetration of a fluid from a region between the metallic housing and the coil, into the region where a connector is connected to the contact connectors. In order to improve the electrical connection between the contact connector associated to the grounding conductor and the metallic housing, for a connection element (31) which is threaded in the metallic housing, a cylindrical metallic part is placed between the contact connector and the metallic housing. A respective sealing element (41, 42) is placed between the connection element and the metallic cylindrical part as well as between said part and the recess of the plug-in base. Such magnet coil arrangements are used in electromechanically-controlled hydraulic valves in which metallic parts accessible from outside must be connected to a grounding conductor.
