Before procurement teams confirm F3SJ-A1805N20, they typically review Omron Photoelectric Sensor, Omron F3Sj B0625P25 and Omron Sensors to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron F3SJ-A1805N20 Safety Light Curtain
The Omron F3SJ-A1805N20 Safety Light Curtain provides Hand protection with a 15 mm beam gap, 120 axis beam, and a 1805 mm protective height for precise detection in safety-critical applications. Designed with a NPN output configuration, it utilizes a Infrared LED (870 nm) light source and a 5 mm lens diameter for accurate sensing and dependable operation. Equipped with a M12 Connector 8-pin connection for fast installation, it operates on 24 VDC power supply voltage to ensure stable and consistent performance. Manufactured by Omron, part of the Omron Safety Light Curtain range, available under the Omron F3SJ Series.
