The Omron F3SG-4SRA1520-45 is an active-production safety light curtain from the F3SG-SR series, packing 38 beams at a 40 mm pitch into a 1520 mm protective height. Detection capability sits at 45 mm — that's arm/foot protection per the spec, not hand/finger. Operating range stretches from 0.3 m out to 20.0 m, so it covers both tight machine guarding and longer access zones. Supply is 24 VDC, and the IP65/IP67/IP67G rating means it handles dust, oil, water jets, and even submersion; the 'G' suffix indicates oil resistance. Temperature range is -30°C to 55°C, which covers most factory floor conditions without derating.
Detection capability is 45 mm, providing arm/foot protection. The 40 mm beam pitch and 38 beams cover the 1520 mm height.
Integration notes
Blanking and muting functions are built in, so you can program fixed or floating blanking to ignore objects like workpiece fixtures, and muting to temporarily bypass the curtain during material transfer. This reduces the need for external safety relay logic for common tasks. Mounting hardware and alignment aids are typically ordered separately; the curtain itself is a two-piece set (emitter and receiver). Wiring is 24 VDC with a standard M12 or pigtail connector depending on the variant — verify the connector type on the specific datasheet for this order code. The 1520 mm height fits standard machine frames; plan for a rigid mounting surface to maintain alignment over the full 20 m range.
