摘要： The disclosure provides a photoelectric sensor that provides useful information to set measurement conditions. The photoelectric sensor includes a light emitting unit having a light emitting element configured to emit detection light toward a detection area, a light receiving unit having a light receiving element configured to receive the detection light from the detection area and to obtain a detection value corresponding to the amount of light received, and a display unit configured to display information about the detection value in the light receiving unit. When the detection value varies across a predetermined threshold, the display unit displays a transit time that is the time from when the detection value crosses the predetermined threshold until when it crosses the predetermined threshold again, and a variation amount of the detection value in the variation.

摘要： A photosensor includes a light projection unit, a light receiving unit, a determination unit that determines a magnitude relation between a received light quantity of the light receiving unit and a threshold value set for the received light quantity; and a threshold value setting unit that sets the threshold value of the received light quantity. The threshold value setting unit calculates for each of a plurality of different wavelength regions, a contrast difference that is a difference between a received light quantity obtained when projection is performed on a detection target on a surface of a workpiece and a received light quantity obtained when projection is performed on a background on the surface of the workpiece, and updates the threshold value based on the contrast difference for a wavelength region among the plurality of wavelength regions in which the contrast difference has a maximum value.

摘要： In a sensor system including a plurality of photoelectric sensor units, a light projecting period arbitrarily determined in each type is provided and mutual interference is prevented between identical types. The sensor system includes the plurality of sensor units coupled by a connector unit while a signal can be transmitted. Each of the sensor units retains type information thereof, and sets a unique identification number by transmitting the signal to each other. Each sensor unit operates after a delay time determined according to the identification number thereof elapses with a synchronous signal as a starting point. The synchronous signal is transmitted with a predetermined period from the sensor unit having a specific identification number in the plurality of sensor units. The delay time of each sensor unit is determined such that an operating period is matched with a predetermined period determined in each piece of the type information.
