PROBLEM TO BE SOLVED: To provide a photoelectric detection switch system that can reduce wiring man-hours by simplifying wires to supply power to a plurality of photoelectric detection switches. SOLUTION: The photoelectric switch system includes a photoelectric switch master unit 1a and a plurality of photoelectric switch slave units 1b. A master unit body 10a of the photoelectric switch master unit 1a and slave unit bodies 10b of a plurality of the photoelectric switch slave units 1b are mutually connectable via a connector 110. An output line L1 for outputting a detection signal DET is connected respectively to the master unit body 10a and each of the slave unit bodies 10b. Power supply lines L2, L3 for supplying power are connected to the master unit body 10a. Power delivery lines L4, L5 are provided to the master unit body 10a and each of the slave unit bodies 10b. The power supplied to the master unit body 10a is sequentially delivered to each of the slave unit bodies 10b via the power delivery lines L4, L5 and the connector 110. COPYRIGHT: (C)2005,JPO&NCIPI
