The Pepperl+Fuchs NBN30-U1-A2 is an inductive proximity sensor designed for non-flush mounting, with a rated sensing distance of 30 mm for detecting metallic objects . It features a 4-wire PNP configuration, providing complementary Normally Open (NO) and Normally Closed (NC) switching outputs for flexible integration into control systems .This sensor operates on a wide DC voltage range of 10 to 30 V, making it compatible with standard industrial power supplies . Constructed with a robust PA (Polyamide) housing and a metal sensing face coated with epoxy powder, it is built to withstand demanding industrial environments .A key feature of the NBN30-U1-A2 is its high ingress protection rating of IP68 and IP69K, ensuring reliable operation even when exposed to dust, water, and high-pressure or steam cleaning processes . It includes LED status indicators—a green LED for power and a yellow LED for switching state—to aid in visual diagnostics .Commonly used for position sensing and end-of-stroke detection in applications like conveyor systems and automated machinery, this sensor is a durable solution for industrial automation .
