The Omron F3SG-4RE1680P14 is a finger-protection light curtain from the F3SG-RE series, rated for 14 mm detection capability and a 1680 mm protective height. It uses 167 infrared beams at a 10 mm pitch to create a sensing field from 0.3 m to 10.0 m, powered by 24 VDC.
Fit and ratings
The 14 mm detection capability means it catches fingers approaching the field, not just hands — that is the difference between a Type 4 finger-safe curtain and a hand-safe model. The 1680 mm protective height covers a tall opening, and the 167 beams at 10 mm pitch give consistent coverage across that height. Rated IP67, so it handles washdown environments and dusty enclosures without a secondary cover. Operating range of 0.3 m to 10.0 m gives flexibility for short-reach or long-reach guarding on a single unit.
