Schneider Electric XU9B18NP340 Photoelectric Sensor

The Schneider Electric XU9B18NP340 diffuse infrared photoelectric sensor is a compact M18 cylindrical device designed for non-contact object detection in industrial automation. With a 12–24 V DC supply, it provides an NPN 3-wire normally open output through an M12 4-pin connector, and draws up to 100 mA. The sensor uses infrared LED as its light source and offers a sharp 1 ms response time with a 500 Hz switching frequency, enabling reliable detection in fast-paced packaging, conveyor lines, and automated handling. Built for harsh environments, its nickel-plated brass housing carries IP65 and IP67 protection and is intended for mounting on cylindrical threaded hardware. Typical applications include packaging equipment, conveyor systems, sorting setups, and assembly or material-handling processes where presence and position sensing are required. This part is produced by Schneider Electric / Telemecanique Sensors and is widely used by maintenance teams, OEMs, and system integrators for repair, retrofit, or new equipment integration. Common replacements include XU9B18PP340, XU5-N18NP340D, and XU1N18NP341WD.
