Omron F3SG-4SRB1040-25 Safety Light Curtain
Omron F3SG-4SRB1040-25 is a Safety Light Curtain designed for 25 mm hand protection across a 1040 mm protective height. Its sensing field contains 52 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the protected machine opening. The specified sensing 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 the safety-system interface. Within the F3SG-SR Series, the F3SG-4SRB1040-25 provides protection beyond one metre in height. For extended machine openings, compare industrial hand detection safety curtains available from Omron safety automation products.

The Omron F3SG-4SRB1040-25 Safety Light Curtain provides 25 mm hand detection across a 1040 mm protective height. Its optical field uses 52 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the monitored machine access area. The specified sensing distance is 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 listed at 82 mA for the emitter and 103 mA for the receiver. The enclosure is rated to both IP65 and IP67.
When evaluating the F3SG-4SRB1040-25, its 25 mm detection size, 1040 mm protective height, 20 mm beam spacing, sensing range, and output configuration should be matched to the guarded opening. These values determine the vertical sensing field and safety-system interface. A shorter model may be appropriate where the full one-metre protective height is not required while retaining the same hand-detection class. For an 800 mm configuration using 40 beams and the same 20 mm beam gap, see Omron F3SG-4SRB0800-25.
