Schneider Electric XS1M18NB370D Proximity Sensor

The Schneider Electric XS1M18NB370D is an inductive proximity sensor (XS1 series) that detects metal objects without contact in industrial automation. Housed in a brass, M18 threaded cylinder designed for flush mounting, it operates from 12–48 V DC with a 3‑wire NPN normally closed output and a maximum current of 200 mA. It uses a 4‑pin M12 connector, provides a sensing distance of 5 mm, and carries an IP67 rating with a rated switching frequency of 2000 Hz, making it reliable in dirty or wet environments. Commonly used on conveyors, packaging machines, assembly lines, and machine tools for presence and position sensing of metallic components, it enables reliable object detection and position feedback across production lines. This sensor is manufactured by Schneider Electric (Telemecanique) and is CE, UL, and CSA certified. For replacement or retrofit, compatible variants include XS1M18NB371, XS618B1NAM12, and XS1M18NA370.
