The Siemens 3RG7200-3CC00 is a SIMATIC PXO610 K80 diffuse photoelectric sensor in an energetic rectangular housing (83x61x25 mm). It runs on DC 10-36V and delivers a 2-meter PNP antivalent output rated at 200 mA, terminated through a 4-pole M12 connector. The IP67 rating means it handles washdown and dusty factory environments without an extra enclosure.
The antivalent output (one PNP normally-open, one PNP normally-closed) gives you complementary switching from a single sensor – useful for detecting both presence and absence without a separate logic inversion. The 200 mA continuous rating covers most PLC digital inputs and small relay coils directly. Mounting dimensions are 83x61x25 mm; the M12 connector mates with standard 4-pole cordsets, so panel wiring stays consistent with other M12-terminated field devices.
