The Siemens 3RG7204-3CC00 is a SIMATIC PXO650 K80 diffuse photoelectric sensor with background suppression. It detects objects from 0.2 to 1 m, outputs a PNP antivalent signal at 200 mA, and runs on 10-36 VDC. The M12 4-pole connector makes panel wiring straightforward, and IP67 keeps it on the machine, not in the cabinet.
Background suppression means the sensor ignores the background beyond the set distance — critical for conveyor or pick-and-place where the belt or backstop could trigger a standard diffuse sensor. The 0.2-1 m range covers short to medium detection zones. PNP antivalent gives both NO and NC outputs on the same 4-pin M12, so you can wire it for fail-safe or complementary logic without extra components.
Integration and mounting notes
The housing is 83x61x25 mm — compact enough for tight machine frames. M12 connector is 4-pole; standard sensor cables with a 4-pin female coupler work. Supply is 10-36 VDC, so it fits 12 V or 24 V control systems without a separate regulator. IP67 means washdown or dust exposure is fine; no extra enclosure needed.
