Abstract
An electronically controlled stepper motor valve utilizes an electric feed through assembly providing electrical connection between the stepper motor and a mating cable connector; wherein the electric feed through assembly includes four individual leads that are sequenced to allow the mating cable connector to be installed in any of four positions, each 90 degrees apart. The ability to use a 90 degree elbow style cable connector allows the EEV footprint to be minimized which provides an advantage when the electric expansion valve is installed in the tight confines of a package system.
