Schneider Electric XU9M18PP340 Photoelectric Sensor

The XU9M18PP340 is a diffuse infrared photoelectric sensor from Schneider Electric / Telemecanique Sensors designed for non-contact object detection in industrial automation. Housed in a nickel-plated brass cylindrical M18 body, it uses a 4-pin M12 connector for a 3-wire PNP normally open output that operates from 12 to 24 V DC with a maximum current of 100 mA. With an infrared light source and a 1 ms response time, it detects the presence and position of workpieces in packaging equipment, conveyors, sorting systems, and automated handling lines. The sensor is rated IP65 and IP67 to withstand challenging factory conditions and is suited for repair, retrofit, or new equipment integration by maintenance teams, OEMs, and system integrators. Common replacements include XU5N18PP340W, XU2B18PP340D, and XU1N18NP341WD, and it carries CE certification.
