Schneider Electric XS1 M18NA370 Inductive Proximity Switch

The Schneider Electric XS1 M18NA370 inductive proximity switch is a cylindrical M18 sensor designed for non-contact detection of metal objects in industrial automation. With a brass housing and flush-mount design, it offers normally open (NO) switching, a 3-wire NPN output, and a rated 12–48 V DC supply, enabling reliable position sensing and object detection across conveyors, packaging equipment, assembly lines, and machine tools. The sensor provides a 5 mm sensing distance, 2 m cable, and IP67 protection for use in demanding environments, and is certified for CE, UL, and CSA. Common replacements include XS1M18NA371, XS618B1NAM12, and XS1M18PA370.
