Abstract:
1. A multi-optical axis photoelectric sensor comprising: a phototransmitter having a plurality of light projecting elements; and a photoreceiver, arranged so as to be opposed to the phototransmitter and having a plurality of light receiving elements that receive light projected from the plurality of light projecting elements, in which 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 is outputted to an external apparatus, wherein the photoreceiver includes a first cable connecting section, 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, 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.
