What this light curtain covers
The Omron F3SG-4SRA0880-25 is a type-4 safety light curtain from the F3SG-SR series, rated for hand protection with a 25 mm detection capability. Its 44 beams at 20 mm pitch create a protective field 880 mm tall, covering access to hazardous machinery zones. Operating range spans 0.3 m to 20.0 m, giving flexibility for both tight machine guarding and longer perimeter setups. The 24 VDC supply is standard for safety controllers and interface modules. Built-in blanking and muting functions let the curtain ignore fixed obstructions (like a fixture) or temporarily suspend detection during a material pass — common in automated assembly and palletizing cells.
Environmental and mounting reality
Rated IP65/IP67/IP67G — dust-tight, protected against temporary immersion, and with added oil resistance. That IP67G rating matters in machining environments where coolant mist and washdown are routine. Operating temperature from -30°C to 55°C covers unheated warehouses and outdoor-adjacent installations. No derating needed for most factory-floor conditions.
