The Omron F3SG-4SRA2280-25 is an active-production safety light curtain from the F3SG-SR series, designed for hand protection with a 25 mm detection capability and a 2280 mm protective height. It uses 114 beams at a 20 mm pitch to create an infrared sensing field spanning 0.3 m to 20.0 m, covering access to hazardous machinery. The 24 VDC supply and IP65/IP67/IP67G rating — dust-tight, waterproof, and oil-resistant — make it suited for washdown environments in food processing, packaging, and automotive lines.
The 25 mm detection capability means this curtain catches a 25 mm diameter object anywhere in the field — typical for hand/finger protection at the access point. The 2280 mm protective height covers tall openings; paired with the 20 m range, it works on long conveyor or robot cell perimeters. The 20 mm beam pitch and 114 beams give dense coverage, reducing the chance of reaching through undetected. Blanking and muting functions allow the curtain to ignore fixed obstructions (e.g., a workpiece fixture) or temporarily bypass during material pass-through, which is common in automated palletizing or press feed applications.
