ABSTRACT:
A solenoid for a solenoid actuator or solenoid valve is encapsulated within a unitary homogenous plastic body which is molded directly about the solenoid coil and the adjacent portion of the solenoid leads so as to seal the coil and leads against the ambient environment and includes a first body portion enclosing and sealing the coil, and an integral second body portion in the form of an externally threaded stem circumferentially surrounding and sealing the adjacent portion of the leads. The externally threaded stem may be used to couple the solenoid to an electrical cable through which the solenoid is energized or to mount the solenoid on a support, such as a barrier wall between a hostile environment to which the sealed solenoid may be safely exposed, and an environment to which the unencapsulated portions of the solenoid leads may be safely exposed.
