Summary:A solenoid assembly has a sealing device 30 disposed in a recess 28 of its over-molded casing 36 to seal electrical leads 24, 26 extending from the coil of the solenoid through the recess. The device sealing device is an elastomeric member having holes 32, 34 through which the electrical leads to pass and a larger portion that is disposed in the recess. With the larger portion pressed into the recess, a force is transferred through the elastomeric material onto the electrical leads to prohibit ingress of contaminants into the windings of the coil. The electrical leads could be either lead wires or rigid pins. The elastomeric material also serves to provide vibration damping.
