Omron F3SG-4SRB0800-25 Safety Light Curtain
Omron F3SG-4SRB0800-25 is a Safety Light Curtain designed for 25 mm hand protection across an 800 mm protective height. Its sensing field uses 40 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the guarded opening. The operating range is specified at 0.3 to 20.0 m or 0.3 to 7.0 m depending on configuration. It operates from a SELV/PELV 24 VDC supply and provides PNP/NPN safety outputs. Within the F3SG-SR Series, the F3SG-4SRB0800-25 provides extended hand-detection coverage.

The Omron F3SG-4SRB0800-25 Safety Light Curtain provides 25 mm hand detection across an 800 mm protective height. Its sensing field uses 40 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the guarded opening. The sensing range is specified at 0.3 to 20.0 m or 0.3 to 7.0 m depending on configuration. It operates from a SELV/PELV 24 VDC ±20% supply and provides PNP/NPN safety outputs. Maximum current consumption is 76 mA for the emitter and 101 mA for the receiver. The enclosure carries IP65 and IP67 protection ratings.
For selection, the F3SG-4SRB0800-25 should be evaluated by its 25 mm detection capability, 800 mm protective height, 20 mm beam spacing, available sensing distance, and PNP/NPN output configuration. These specifications determine the protected vertical area and electrical compatibility with the machine safety system. A shorter model can be used where the guarded opening requires less height, while a taller configuration can extend the protected field without changing the listed hand-detection class. For a larger 1200 mm protective height using 60 beams with the same 20 mm beam gap, see Omron F3SG-4SRA1200-25.
