Omron F3SG-4RA0990-30 Safety Light Curtain
Omron F3SG-4RA0990-30 is a Safety Light Curtain designed for 30 mm hand and arm protection across a 990 mm protective height. Its sensing field contains 48 infrared beams arranged with a 20 mm beam gap to detect opaque objects through the guarded opening. The specified operating range is 0.3 to 20.0 m or 0.3 to 7.0 m depending on configuration. A SELV/PELV 24 VDC supply powers the unit, while PNP/NPN outputs provide safety-system connectivity. Within the F3SG-R Series, the F3SG-4RA0990-30 provides protective coverage approaching one metre.

The Omron F3SG-4RA0990-30 Safety Light Curtain provides 30 mm hand and arm detection across a 990 mm protective height. Its optical field contains 48 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the protected area. The sensing range is specified at 0.3 to 20.0 m or 0.3 to 7.0 m depending on configuration. The unit operates from a SELV/PELV 24 VDC ±20% power supply and provides PNP/NPN safety outputs. Maximum current consumption is 50 mA for the emitter and 80 mA for the receiver. The enclosure carries both IP65 and IP67 protection ratings.
Selection of the F3SG-4RA0990-30 should consider its 30 mm detection diameter, 990 mm protective height, 20 mm beam spacing, available sensing distance, and output configuration. These parameters establish the size and vertical extent of the protected field. Models with the same 30 mm detection class can provide shorter coverage where a smaller guarded opening is involved. For a compact 350 mm configuration using 16 beams while retaining a 20 mm beam gap, see Omron F3SG-4RA0350-30.
