It runs on 24 VDC and carries IP65/IP67/IP67G ingress protection, meaning it's dust-tight, water-resistant, and oil-resistant — tough enough for washdown zones or dusty conveyor lines. The protective height is 280 mm, built from four beams spaced at 80 mm pitch. Built-in blanking and muting functions handle common production-line scenarios: blanking lets you ignore fixed obstructions (like a fixture or conveyor rail) within the field, and muting temporarily suspends the safety output during a material pass-through. No external controller needed for those modes — the logic is in the body. The 85 mm detection capability means it catches hand-sized objects — finger detection this is not, but for body or torso presence it's exactly what you want. ## Mounting & Integration Notes Mounting is through the standard end-bracket system on the F3SG-SR family — no special tooling needed. The IP67G rating (the 'G' stands for oil-resistant) makes it a fit for machining centers where coolant mist is constant. Power is 24 VDC, so it taps straight into the control cabinet supply; no separate transformer needed. The 20 m range gives you flexibility to sit the emitter and receiver across a wide aisle or a long conveyor zone. The 85 mm detection capability is the key spec for your risk assessment: it's rated for hand and body detection, not finger. If your application requires finger detection (14 mm or smaller), this isn't the curtain — you'd step down to the F3SG-RR series. But for point-of-entry guarding around a palletizer, press brake, or robot cell, 85 mm is standard. The 280 mm protective height covers a typical waist-to-shoulder zone; stack two units if you need full-height coverage. Operating range of 0.3 m to 20.0 m means it works in tight spaces (minimum 300 mm separation) and wide spans alike. The 80 mm beam pitch with four beams gives you a coarse but reliable detection matrix — fast response, fewer beams to align, and less prone to nuisance trips from dust or chips.","metaTitle":"Omron F3SG-4SRA0280-85 Light Curtain, 85mm Detection, 20m Ra","metaDescription":"Active-production safety light curtain from the F3SG-SR series. 85mm detection capability, 20m operating range, IP65/IP67/IP67G, 24VDC.
