Omron F3SG-4SRA2480-25 Safety Light Curtain, 25mm Detection

The Omron F3SG-4SRA2480-25 is a Type 4 safety light curtain from the F3SG-SR series, built for hand protection with a 25 mm detection capability. That 25 mm resolution means it catches a finger or hand reaching into the hazard zone — not just a full-body presence — so it suits point-of-operation guarding on presses, assembly stations, and packaging machinery where an operator's hands enter the danger area. The 2480 mm protective height and 124 beams at 20 mm pitch cover a tall opening — think a large robot cell entry or a conveyor infeed. The 0.3 m to 20.0 m operating range gives flexibility for both tight machine guarding and longer perimeter setups; at the short end it fits compact stations, at the long end it spans wide access points without needing a reflector. Rated IP65/IP67/IP67G — the G suffix means the optics resist oil and washdown environments, so this curtain holds up on food-and-beverage lines or machining centers where coolant mist and high-pressure cleaning are routine. The 24 VDC supply is standard for safety circuits; the blanking and muting functions let you program out fixed obstructions (like a conveyor frame) or temporarily bypass the curtain during a pallet pass, which saves having to add extra safety relays.
