Abstract
The invention provides a multi-optical axis photoelectric sensor capable of improving workability of wiring. The sensor outputs to an external apparatus a safe signal generated based upon an interrupted state of at least one optical axis among optical axes formed between the phototransmitter and the photoreceiver. The photoreceiver includes a first cable connecting section (end section case), connected with a cable including a power line for receiving power supply from the external apparatus and an output line for outputting a safe signal to the external apparatus, and a second cable connecting section (end section case), connected with a cable including a power line for performing power supply to the phototransmitter and a communication line for transmitting or receiving a timing signal that defines timing for light projection of the light projecting elements.
