摘要： A photoelectric sensor transmits pulsed light repetitively, receives light which may include noise and generates a corresponding electrical reception signal. The level of reception signal is compared with a specified threshold value at a timing which is slightly delayed from the timing of light transmission. A sensor output is generated on the basis of the result of this comparison. If periodically changing noise is present and the reception signal has an AC waveform, the level of the reception signal is compared with another threshold value proximal to an AC zero level. The timing of next light transmission is controlled on the basis of the result of the second comparison.

摘要： A proximity sensor 717 comprising a combination of an arbitrarily selected one of a plurality of types of detection end modules 707, a plurality of types of output circuit modules 709 and a plurality of types of outer shell cases 711. The detection end module 707 includes an integrated arrangement having a detection coil assembly 705, 701, 702) with the detection characteristic self-completed by a mask conductor 700 for reducing the conductor detection sensitivity in a specific peripheral area where the outer shell case is assumed to exist, and a detection circuit assembly (703) 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.

摘要： Each of a detection sample object and a non-detection sample object is illuminated with S-polarization light, for instance. S-polarization light and P-polarization light reflected from each sample object are detected by different photodetecting elements. Glossiness values and light quantities of the detection and non-detection sample objects are judged based on detection outputs of the photodetecting elements, and a glossiness difference and a light quantity difference are calculated. An evaluation function having at least one of the glossiness and the light quantity as a variable is determined by using the glossiness difference and the light quantity difference. Thresholds for object discrimination are calculated based on evaluation function values of the detection and non-detection sample objects.

摘要： A reflective-type photoelectric switch projects emitted light from a light-emitting element toward a detection zone by a light-projecting optical system, and guides reflected light from an object to be detected in the detection zone to a light-receiving element by a light-receiving optical system. A special optical element is used in part of at least one of the two optical systems. The optical element functions to diverge light in a direction parallel to a plane containing the optic axes of the light-emitting and light-receiving elements, and condense light in a direction perpendicular to the same plane. As a result, it is possible to detect, with excellent sensitivity, both an object which is far from the switch and an object very near the switch.
