Omron F3SG-4RA0320-14 Safety Light Curtain
Omron F3SG-4RA0320-14 is a Safety Light Curtain configured for 14 mm finger protection across a 320 mm protective height. Its sensing field contains 31 infrared beams arranged with a 10 mm beam gap 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 supply and provides PNP/NPN outputs. Within the F3SG-R Series, the F3SG-4RA0320-14 provides compact finger-level detection.

The Omron F3SG-4RA0320-14 Safety Light Curtain provides 14 mm finger detection across a 320 mm protective height. Its sensing field uses 31 infrared beams arranged with a 10 mm beam gap, giving closely spaced optical coverage for detecting opaque objects. The specified operating range is 0.3 to 10.0 m or 0.3 to 3.0 m depending on configuration. Power is supplied at SELV/PELV 24 VDC ±20%, while PNP/NPN outputs provide the electrical interface with the machine safety system. Emitter current is specified at 55 mA maximum and receiver current at 75 mA maximum. The enclosure carries IP65 and IP67 protection ratings.
For selection, the F3SG-4RA0320-14 should be evaluated by its 14 mm detection capability, 320 mm protective height, 10 mm beam spacing, available sensing distance, and PNP/NPN output configuration. These specifications define the object size detected, vertical protected area, and electrical compatibility with the safety control architecture. When a taller finger-protection field is required while retaining the same 10 mm beam gap, a higher protective-height model can be considered. For a 400 mm configuration using 39 beams and the same 14 mm finger-detection class, see Omron F3SG-4RA0400-14.
