The Siemens 3RG7201-6CC00 is a SIMATIC PXO620 K80 retro-reflective photoelectric sensor with a polarisation filter, sized at 83x61x25 mm. It runs on DC 10-36 V and delivers a PNP antivalent output rated at 200 mA over a 6 m sensing range. The PG11 gland and 4-pole connection make it a direct swap for existing PXO620 mounts in the field.
The 10-36 V DC supply covers both 12 V and 24 V control loops without a regulator. PNP antivalent means two complementary outputs — one normally open, one normally closed — so a single sensor can signal a PLC input and a panel lamp simultaneously. The 200 mA load capacity handles most relay coils and indicator banks directly. IP67 lets it live in washdown zones or outdoor cabinets without a secondary enclosure.
