Abstract
A multi-optical axis photoelectric sensor includes a sensor unit configured to detect whether each of plural optical axes formed between a projection unit and a light receiving unit is in a light shielding state, the sensor unit including the projection unit and the light receiving unit, the projection unit including plural projection elements, the light receiving unit including plural light receiving elements disposed opposite the plural projection elements. The multi-optical axis photoelectric sensor also includes a control unit that controls the light receiving unit, communication cables of plural signal wirings through which a signal is input to and output from the control unit, and a communicator that conducts communication between the control unit and an external device through a common wiring sharing one of the communication cables with a communication wiring.
