Omron F3SG-4RA1950-30 Safety Light Curtain
Omron F3SG-4RA1950-30 is a Safety Light Curtain designed for 30 mm hand and arm protection across a 1950 mm protective height. Its sensing field contains 96 infrared beams arranged with a 20 mm beam gap to detect opaque objects throughout a tall guarded access area. The operating 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. Within the F3SG-R Series, the F3SG-4RA1950-30 provides nearly two metres of vertical protection. For extensive machine openings, compare large protective-height safety light curtains available through Omron machine safety products.

The Omron F3SG-4RA1950-30 Safety Light Curtain provides 30 mm hand and arm detection across a 1950 mm protective height. Its sensing field contains 96 infrared beams positioned with a 20 mm beam gap, providing extensive vertical coverage for detecting opaque objects through the guarded 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 ±20% supply and provides PNP/NPN safety outputs. Maximum current consumption is 75 mA for the emitter and 95 mA for the receiver. The enclosure carries IP65 and IP67 ratings.
For installation, the F3SG-4RA1950-30 should be evaluated by its 30 mm detection capability, 1950 mm protective height, 20 mm beam spacing, required operating distance, and output format. These specifications make it the tallest configuration in this group and define the extensive vertical field available for machine access monitoring. If a smaller protected opening is involved, a shorter F3SG-R model can provide the same 30 mm protection class with fewer beams. For a 990 mm configuration using 48 beams, see Omron F3SG-4RA0990-30.
