The Omron F3SG-4SRB1200-25 is a type-4 safety light curtain from the F3SG-SR series, sized for hand protection with a 25 mm detection capability and a 1200 mm protective height. The 20 mm beam pitch and 60 beams give it a 0.3 m to 20.0 m operating range, covering a wide access area with a single pair. Blanking and muting functions are built in, so it handles pass-through applications without hard guarding on every cycle.
Runs on 24 VDC supply. The IP65/IP67/IP67G rating means it stands up to washdown environments and oil mist — the G suffix indicates oil-resistant seals, which matters in machining cells. Operating temperature from -30°C to 55°C covers unheated warehouses and refrigerated areas. The 25 mm detection capability is the spec that decides hand vs. finger protection; at 25 mm it catches a hand but not individual fingers, so it is the right choice for perimeter and access guarding where finger-level resolution is not required.
