ABSTRACT:
A solenoid having a bobbin with a rectangular core hole in which is mounted an armature having a rectangular cross section, and a pole piece having a rectangular cross section. The bobbin has a magnet wire coil wound around a bobbin tubular body which is rectangular in cross section. The bobbin has an upper flange and a lower flange that encloses the ends of the coil. A tubular can is seated around the bobbin. A top flux plate is seated on the upper can surface and a bottom flux plate is seated under the lower can surface. The flux plates are secured to the bobbin flanges. A sealing, electrical insulating heat dissipating material is disposed inside of the tubular can which seals the coil and insulates the coil from the flux plates, tubular can and solenoid mounting screws.
