The Omron F3SG-4RE1200P14 is a Type 4 safety light curtain from the F3SG-RE series, built for finger detection with a 14mm detection capability. That 14mm beam pitch means it catches a fingertip — not just a hand — so it suits press brakes, assembly stations, and other tight-access guarding where you need to stop the machine before someone gets pinched. The protective height of 1200mm covers a typical standing operator zone, and the operating range spans 0.3m to 10.0m, which gives you flexibility to mount the emitter and receiver across a work cell without losing detection. It runs on 24VDC and carries an IP67 rating — dust-tight and waterproof — so it can handle washdown environments or dusty shop floors without an extra enclosure.
The 14mm detection capability is the headline spec for finger protection — it's the smallest object the curtain reliably sees. If your application requires hand-only detection (30mm), this is overkill, but if you're guarding a guillotine or a robot cell where an operator's finger might reach into the danger zone, the 14mm beam pitch is what you need. The 119 beams cover the 1200mm height with a 10mm pitch, so there are no gaps large enough for a finger to slip through. The operating range of 0.3m to 10.0m means you can set the emitter and receiver as close as 300mm apart for compact stations, or as far as 10m for larger cells — but the minimum range matters: if you need to guard a gap under 300mm, this curtain won't work without a mirror or a different model.
