Omron F3SG-4RA0350-30 Safety Light Curtain
Omron F3SG-4RA0350-30 is a Safety Light Curtain designed for 30 mm hand and arm protection across a 350 mm protective height. Its optical field uses 16 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. It operates from a SELV/PELV 24 VDC supply and provides PNP/NPN outputs for the safety system. Within the F3SG-R Series, the F3SG-4RA0350-30 provides compact hand and arm detection.

The Omron F3SG-4RA0350-30 Safety Light Curtain provides 30 mm hand and arm detection over a 350 mm protective height. Its optical field consists of 16 infrared beams arranged with a 20 mm beam gap for detecting opaque objects across the guarded opening. The sensing distance 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 outputs. Maximum current consumption is specified at 40 mA for the emitter and 75 mA for the receiver. IP65 and IP67 enclosure ratings provide the listed ingress protection for this model.
When selecting the F3SG-4RA0350-30, the 30 mm detection diameter, 350 mm protective height, 20 mm beam spacing, sensing distance, and PNP/NPN output format are the main specifications to compare. These parameters determine the protected vertical area and electrical connection requirements. A shorter or taller F3SG-R model can be chosen while retaining the same hand and arm protection class and beam spacing. For a taller 670 mm version using 32 beams with the same 20 mm beam gap, see Omron F3SG-4RA0670-30.
