Schneider Electric XU9B18PP340 Photoelectric Sensor

The Schneider Electric XU9B18PP340 photoelectric sensor delivers reliable non-contact object detection in industrial automation, leveraging diffuse infrared sensing in a compact cylindrical M18 housing. As a member of the XU9 family, it detects the presence and position of workpieces on packaging machines, conveyor lines, sorting systems, and automated handling equipment with diffuse optical sensing and provides a PNP, 3-wire output that is normally open. Operating from 12–24 V DC, it draws up to 100 mA and terminates via an M12 4-pin connector, with a nickel-plated brass housing and a cylindrical threaded mount for robust installation. The sensor carries IP65 and IP67 protection, and responds in 1 ms to rapidly changing conditions, making it suitable for fast-paced production lines. The infrared LED light source supports reliable detection across typical automation environments, and the unit is designed for repair, retrofit, or new equipment integration by maintenance teams, OEMs, and system integrators. Common replacements include XU9M18PP340, XU5N18PP340W, and XU2B18PP340D.
