Omron F3SG-4RA0720-14 Safety Light Curtain
Omron F3SG-4RA0720-14 is a Safety Light Curtain providing 14 mm finger protection across a 720 mm protective height. Its optical field contains 71 infrared beams arranged with a 10 mm beam gap, creating dense sensing coverage for detecting opaque objects through the protected opening. The operating range is specified at 0.3 to 10.0 m or 0.3 to 3.0 m depending on configuration. It operates from a SELV/PELV 24 VDC supply and provides PNP/NPN safety outputs. Within the F3SG-R Series, the F3SG-4RA0720-14 combines fine detection with extended vertical coverage.

The Omron F3SG-4RA0720-14 Safety Light Curtain provides 14 mm finger detection across a 720 mm protective height. Its protective field consists of 71 infrared beams positioned with a 10 mm beam gap, creating dense optical coverage for detecting opaque objects through the guarded opening. The operating range is specified at 0.3 to 10.0 m or 0.3 to 3.0 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 85 mA for the receiver. The enclosure carries IP65 and IP67 ratings.
For model selection, the F3SG-4RA0720-14 should be matched to the required 14 mm detection size, 720 mm protective height, 10 mm beam spacing, sensing distance, and output configuration. These characteristics define the fine-protection field and vertical coverage available at the guarded machine opening. Other F3SG-R variants provide shorter finger-protection heights where the access area is smaller. For a 640 mm configuration using 63 beams with the same 14 mm detection class and 10 mm beam gap, see Omron F3SG-4RA0640-14.
