Omron F3SG-4RA1550-30 Safety Light Curtain
Omron F3SG-4RA1550-30 is a Safety Light Curtain providing 30 mm hand and arm protection across a 1550 mm protective height. Its protective field contains 76 infrared beams positioned with a 20 mm beam gap for detecting opaque objects through a tall 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 supply and provides PNP/NPN safety outputs for machine safety integration. Within the F3SG-R Series, the F3SG-4RA1550-30 provides 1550 mm vertical protection.

The Omron F3SG-4RA1550-30 Safety Light Curtain provides 30 mm hand and arm detection across a 1550 mm protective height. Its protective field consists of 76 infrared beams arranged at a 20 mm beam gap for detecting opaque objects throughout a tall machine 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 safety outputs. Maximum current consumption is 65 mA for the emitter and 90 mA for the receiver. The enclosure is rated to both IP65 and IP67.
When choosing the F3SG-4RA1550-30, the 30 mm detection capability, 1550 mm protective height, 20 mm beam spacing, sensing range, and output configuration should be considered together. These parameters determine whether the protective field matches the size of the guarded access zone. Shorter F3SG-R variants retain the same protection class while reducing beam count and vertical coverage. For an 830 mm configuration using 40 beams with the same 20 mm beam gap, see Omron F3SG-4RA0830-30.
