Schneider Electric XS4P18PA370D Inductive Proximity Switch

Schneider Electric XS4P18PA370D is a cylindrical M18 inductive proximity switch designed for non-contact detection of metal parts in industrial automation systems, commonly deployed on conveyors, packaging equipment, assembly lines, and machine tools to monitor moving parts and workpieces. It features a PNP, 3-wire normally open output, 12–24 V DC rated voltage, and a 200 mA maximum current, with an M12 4-pin connector for straightforward integration with standard controllers. The sensor uses a PBT housing with flush-mount installation, an IP67 enclosure rating for dusty or wet environments, and an 8 mm sensing distance with a switching frequency up to 1000 Hz to support high-speed automation. Certified for CE, UL, and CSA, the XS4P18PA370D belongs to Schneider Electric / Telemecanique Sensors' XS4 family and is designed for repair, retrofit, or new equipment integration, with common replacements XS4P18PA370, XS2M18PA370, and XS1N18PA349D.
