The Omron F3SJ-A0545N20 Safety Light Curtain uses 20 mm detection capability for hand protection across a 545 mm protective height. Its sensing field contains 36 infrared beams positioned with a 15 mm beam gap and supports an operating distance of 0.2 to 9 m. The light curtain operates from 24 VDC and connects through an M12 8-pin connector. Two NPN transistor outputs are provided with a maximum load current of 300 mA each. The enclosure carries an IP65 rating and supports operation from -10 to 55°C without icing.
The F3SJ-A0545N20 should be selected by matching its 20 mm detection capability and 545 mm protective height to the guarded opening. Beam spacing, operating distance, and NPN output format should also match the safety control system. For a shorter hand and arm protection model with a 245 mm protective height and 25 mm beam gap, see Omron F3SJ-A0245P30.
