A proximity sensorcomprising a combination of an arbitrarily selected one of a plurality of types of detection end modules, a plurality of types of output circuit modulesand a plurality of types of outer shell cases. The detection end moduleincludes an integrated arrangement having a detection coil assembly () with the detection characteristic self-completed by a mask conductorfor reducing the conductor detection sensitivity in a specific peripheral area where the outer shell case is assumed to exist, and a detection circuit assembly () with the coil of the detection coil assembly as a resonance circuit element. The characteristics of the proximity sensor are completely adjusted before shipment. As a result, the adjustment of the characteristics which otherwise might be required each time is eliminated even in the case of the combination with an outer shell case of a different material. Thus, the commodity design and production are facilitated for a great variety of commodity specifications.

Proximity sensor

A connector has a conductive terminal assembly including a plug-adaptable conductive terminal electrically connected with a circuit assembly and a pin holder for holding the conductive terminal The terminal assembly is sized to be able to be inserted from the front-end side of an outer shell case A cylindrical holding member has openings at both ends to enable the conductive terminal assembly to be inserted, a joint to position the conductive terminal assembly to itself, and is fixed from the rear-end side of the outer shell case. In addition, the detection coil assembly and the conductive terminal assembly are electrically connected with each other via a flexible connection member.

An electronic equipment such as a proximity sensor. A groove for discharging air is formed at coil casing ( ) arranged at a front surface of the proximity sensor. An opening ( ) is formed at a clamp portion ( ) holding a code ( ) behind a metal casing ( ). The proximity sensor ( ) is held at a low pressure, and resin is supplied through the opening ( ) at the clamp portion ( ), whereby the casing can be filled with the resin in a short time.
