Safety light curtain for arm/foot detection
The Omron F3SG-4SRB0560-45 is an active-production safety light curtain from the F3SG-SR series, designed for arm and foot protection with a 45 mm detection capability and a 560 mm protective height. It operates on a 24 VDC supply and covers an operating range from 0.3 m to 20.0 m, making it suitable for guarding access points around machinery where personnel need to be detected before reaching hazardous zones.
The 45 mm detection capability means this curtain resolves objects of that diameter or larger — typical for arm/foot detection per the protection type. The 40 mm beam pitch gives 14 beams across the 560 mm protective height; that beam count and pitch define the resolution and the minimum object size the curtain will catch. The 0.3 m to 20.0 m range covers short machine access up to long conveyor entries, but the actual safe distance from the hazard must be calculated per ISO 13855 using the curtain's response time — not just the range figure.
Washdown-ready enclosure
Rated IP65/IP67/IP67G, the housing is dust-tight, protected against temporary immersion, and oil-resistant — the IP67G suffix adds oil resistance common in machine-tool environments. For washdown zones, verify that the connector and cable entry match the enclosure rating; the IP67G rating suggests it can handle the occasional caustic spray from a CIP cycle, but the cable gland and mating connector must also carry that rating to maintain the seal.
Blanking and muting built in
The F3SG-4SRB0560-45 includes blanking and muting functions. Blanking lets you optically mask fixed obstructions (like a machine frame) within the field without disabling the curtain; muting temporarily suspends the safety output during a defined material pass (e.g., a pallet entering a press). These are configurable via the controller, not hardwired — check the F3SG-SR programming guide for the specific blanking window setup.
