1. A method of assembling an inductive proximity sensor to maintain inductive coil wound bobbins in fixed relation to an inductive core within a housing, said method comprising the steps of:

  • configuring each of two inductive coil wound bobbins with an integral ledge cantilevered from an inside surface thereof for forming a pocket under the integral ledge at a bottom of each bobbin;

    disposing each inductive coil wound bobbin around a corresponding leg of the inductive core;

    containing a foot of each core leg into the pocket of the corresponding bobbin under the integral ledge thereof;

    inserting each of two legs of a thruster element into a corresponding bobbin, wherein each leg rests upon the ledge of the corresponding bobbin;

    disposing the inductive core, inductive coil wound bobbins, and thruster element into the housing;

    disposing a spring element on a top surface of the thruster element; and

    compressing the spring element against the top surface of the thruster element to render the core and wound bobbins in a fixed relationship to each other in the housing.
