  • Patent number: 10429510
    Abstract: A photoelectric sensor is configured to detect an object by reception of light from a light projecting unit in a light receiving unit. The photoelectric sensor differentiates a sampled light reception amount with respect to time to calculate a variation in the light reception amount per unit time, and sets as a threshold a light reception amount corresponding to an extreme value of the variation in the light reception amount. In this manner, the threshold is set with the variation in the light reception amount per unit time taken into account, thereby enhancing the accuracy in detection of the object by comparison between the light reception amount and the threshold, to allow minimization of jitter of a detection signal from the photoelectric sensor to a programmable logic controller.
