Abstract
A sensor has a metal case with a sensing coil at one end and a shielded cable extending from the other. In one use it is placed in proximity to rotating machinery to sense imbalance by position change of the shaft. A pair of suitably sized metal cylinders which are precisely interlocked by dielectric material provides for firm mechanical and electrical connections to the inner and outer conductors of the associated shielded cable. In addition a four step injection molding process provides for accurate and secure location of the sensing coil. And at the same time the entire structure because of the injection molding and associated seals is moisture proof. Other uses include temperature and velocity sensing. In an alternative embodiment only a two-step injection molding process is utilized with a somewhat simplified procedure.
