The Omron F3SG-4SRA1360-25 is an active-production safety light curtain from the F3SG-SR series, built for hand protection with a 25 mm detection capability. That 25 mm figure means the curtain reliably catches a finger or hand entering the field — it is not a body- or presence-only sensor. The 1360 mm protective height and 68 beams at 20 mm pitch cover a tall access zone, so it suits large machine openings or conveyor in-feed areas where personnel reach into the hazard. Rated operating range spans 0.3 m to 20.0 m, which gives flexibility for both tight cell guarding and longer perimeter setups. The 24 VDC supply is standard for safety circuits, and the IP65/IP67/IP67G rating means the sensor body and optics withstand washdown environments — the IP67G suffix adds oil resistance, making it a fit for machining centers or press lines where coolant mist is present.
The 25 mm detection capability defines the smallest object the curtain reliably sees — a hand or finger, not just a torso. For access-guarding applications per IEC 61496, this is the key parameter that sets the minimum safe distance from the hazard. The 1360 mm protective height and 68 beams mean the curtain covers a 1.36 m vertical zone, so an integrator sizing for a 1.5 m opening would need a taller model or multiple curtains. The blanking and muting functions are onboard features, not add-on modules. Fixed blanking lets you ignore stationary objects like a machine frame in the field of view; muting temporarily suspends the curtain during a material pass-through. These are programmed via the controller, so the part itself carries the hardware capability. The IP65/IP67/IP67G seal means it handles hose-down cleaning and oil mist — the G variant is specifically tested against oil exposure, common in hydraulic or stamping areas.
