A coated electric wire is wound around a detection circuit in a planar manner for the purpose of electrostatic shield. This winding is performed, for example, spirally in a single layer. In the case where there are further provided a detection circuit board including a detection circuit and a cylindrical case, the coated electric wire is wound around the detection circuit board in a planar manner, wherein the direction of the axis of the cylindrical surface accords with the direction of the axis of the case. Consequently, there can be provided a sensor device in which the detection circuit can be electrostatically shielded with ease.

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.

Proximity sensor

A proximity sensor according to the present invention includes protrusions that are provided on a wire-winding drum of a coil spool around which a lead wire of a detection coil is wound, that protrude toward the center from not less than three points distributed in the range exceeding a semi-circle on the circumference of the wire-winding drum and that are elastically brought into contact with the shaft of the core, respectively, thereby coaxially positioning the coil spool and the shaft of the core.

Proximity sensor with improved positioning accuracy for detection coil peripheral members

In a light curtain generating device comprising a pair of pillar assemblies for supporting arrays of light emitting and receiving units which are placed opposite to each other so as to form a light curtain for detecting an object between the pillar assemblies, the light emitting and receiving unit arrays each consist of a group of single-beam optical modules so that the length of the arrays of light emitting and receiving units and the pitches of the individual light emitting and receiving units can be selected at will. Therefore, the light curtain generating device can readily adapt itself to each particular application at low cost and in a highly precise manner.
