A solenoid arrangement including a coil of electrically conductive wire and a yoke of magnetic material surrounding the coil. The coil is completely encapsulated by a thermosetting resin, the resin being located between the coil and the yoke, and the yoke being encapsulated by a thermoplastic resin. Preferably, the thermosetting resin is an epoxy resin, and the thermoplastic resin is nylon. The yoke includes a side wall extending around the entire periphery of the coil, a top wall, and a bottom wall, the side, top, and bottom walls forming a box-like housing which substantially completely encloses the coil. A stationary armature extends from the top wall of the yoke into the center of the spool upon which the coil is wound, and a sleeve for accommodating a core tube extends from the bottom wall into the center of the spool.
