Zusammenfassung:	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.
