Omron F3SG-4RA0400-14 Safety Light Curtain
Omron F3SG-4RA0400-14 is a Safety Light Curtain providing 14 mm finger protection over a 400 mm protective height. Its sensing field contains 39 infrared beams arranged at a 10 mm beam gap for detecting opaque objects across the guarded machine opening. The specified sensing range is 0.3 to 10.0 m or 0.3 to 3.0 m, depending on configuration. It operates from a SELV/PELV 24 VDC supply and provides PNP/NPN safety outputs. Within the F3SG-R Series, the F3SG-4RA0400-14 combines fine detection with 400 mm vertical coverage.

The Omron F3SG-4RA0400-14 Safety Light Curtain uses 14 mm finger detection across a 400 mm protective height. Its sensing field contains 39 infrared beams positioned with a 10 mm beam gap to detect opaque objects entering the protected opening. The operating range is specified at 0.3 to 10.0 m or 0.3 to 3.0 m depending on configuration. A SELV/PELV 24 VDC ±20% supply powers the unit, while PNP/NPN outputs provide safety-system connectivity. Maximum current consumption is 60 mA for the emitter and 80 mA for the receiver. The enclosure carries both IP65 and IP67 protection ratings.
For model comparison, the F3SG-4RA0400-14 is primarily defined by its 14 mm detection capability, 400 mm vertical protection, 10 mm beam spacing, sensing range, and output configuration. These specifications should be matched to the guarded opening and safety control arrangement. A shorter model can be used where less vertical coverage is required while maintaining the same finger-detection class. For a 320 mm protective height with 31 beams and the same 10 mm beam gap, see Omron F3SG-4RA0320-14.
