Schneider Electric XU9-N18PP340D Photoelectric Sensor

The Schneider Electric XU9-N18PP340D is a cylindrical M18 diffuse photoelectric sensor that detects object presence using infrared light in industrial automation systems. This 12–24 V DC, 3‑wire PNP normally open sensor features an M12 4‑pin connection, nickel-plated brass housing, and IP65/IP67 protection, making it suitable for packaging machines, conveyor lines, and automated handling equipment. With a 1 ms response time and a 500 Hz switching frequency, it provides reliable object detection and position sensing where non-contact sensing is required. Part of Schneider Electric / Telemecanique Sensors’ XU9 family, the XU9-N18PP340D is commonly used for repair, retrofit, or integration into new equipment; common replacements include XU9B18PP340, XU9M18PP340, and XU5N18PP340W.
