The Omron F3SJ-A1995P30 has a 30 mm detection capability for hand/arm protection. It uses 80 beams at a 25 mm pitch to cover a 1995 mm protective height. Operating range runs from 0.2 m to 7.0 m, which covers most machine guarding distances without needing a separate lens set.
What the 30 mm detection rating means for fit
30 mm detection capability is the smallest object the curtain reliably sees — anything smaller passes through undetected. That's the standard hand/arm protection class per IEC 61496-2, so it's suitable for guarding access where a hand might reach into a press, a robot, or a packaging machine. If you need finger protection (14 mm), this isn't the model; if the risk assessment calls for hand/arm, this is the right spec.
