What the 30mm detection capability means for guarding
That 30mm figure is the minimum object size the curtain reliably detects — fingers smaller than 30mm can pass through undetected, so this curtain is sized for hand and arm hazards, not fingertip protection. It uses 16 beams at a 25mm pitch to cover a 395mm protective height, with an operating range from 0.2m to 9.0m, meaning it can guard a reach zone up to 9 meters across.
Deployment context: washdown and muting
The F3SJ-A0395P30 also carries Blanking and Muting Function features: blanking lets you disable selected beams for a fixed obstruction (like a fixture passing through the field), while muting temporarily suspends the safety output during a material-handling cycle, avoiding nuisance trips. Both are configurable without external logic modules on this series.
It runs on 24VDC supply and operates from -10°C to 55°C.
