It outputs an NPN open-collector signal (sinking, 100 mA max) and operates on 10–30 VDC. The plastic M18 cylindrical body carries IP67 and IP69K ingress ratings, making it a candidate for washdown zones in food, beverage, and packaging lines. Switching mode is selectable Light-On or Dark-On, and the red LED indicator is visible through the right-angle lens face. Built-in reverse polarity and short circuit protection on both supply and output reduce field failure risk without an external diode or fuse. ## Integration Notes Mounts via the 17 mm diameter cylindrical body. Prewired 2 m cable with bare ends. Right-angle lens faces the target. No separate amplifier needed.","metaTitle":"Omron E3FA-LN122M Photoelectric Sensor, Diffuse, NPN, 200 mm","metaDescription":"Active-production diffuse photoelectric sensor, NPN output, 200 mm range, IP67/IP69K, 10-30 VDC, 2 m cable.
