Omron F3SG-4RA0640-14 Safety Light Curtain
Omron F3SG-4RA0640-14 is a Safety Light Curtain configured for 14 mm finger protection across a 640 mm protective height. Its sensing field consists of 63 infrared beams positioned with a 10 mm beam gap, creating closely spaced optical detection across 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-4RA0640-14 combines fine detection with 640 mm coverage. For extended finger-level guarding, compare 14 mm machine protection light curtains from Omron machine safety solutions.

The Omron F3SG-4RA0640-14 Safety Light Curtain provides 14 mm finger detection across a 640 mm protective height. Its optical field contains 63 infrared beams arranged with a 10 mm beam gap, creating closely spaced sensing coverage across the guarded opening. The specified operating range is 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 listed at 60 mA for the emitter and 85 mA for the receiver. The enclosure carries both IP65 and IP67 ingress-protection ratings.
When choosing the F3SG-4RA0640-14, the 14 mm detection capability, 640 mm protective height, 10 mm beam spacing, sensing range, and PNP/NPN output format are the key parameters to check. These specifications define the fine-detection field and its vertical coverage. A shorter finger-protection model can be selected where less height is required without changing the listed detection class or beam spacing. For a compact 160 mm version using 15 beams with the same 10 mm beam gap, see Omron F3SG-4RA0160-14.
