Abstract
An adjustable solenoid assembly with an adjustable threaded pole having an interference fit section to be used with a complementary threaded receiver (e.g., the bore of the top plate) with an interference fit section. The adjustable threaded sections are used to pull or push the interference fit sections together and allow for precise locating of the interference fit sections and adjustment. The threaded pole may be used to set and maintain a precision working air gap between the pole piece and the plunger of the electromagnetic solenoid assembly. The interference fit holds the pole piece into location while still allowing the solenoid to be adjustable without a loss in flux density.
