The inductive proximity sensor NJ40+U4+E from Pepperl+Fuchs is a robust and reliable component for use in demanding industrial environments. With a rated switching distance of 40 mm, it enables precise detection of metallic objects without physical contact. The configuration as an NPN normally open (NO) switch with a 3-wire DC output ensures clear signal transmission and is ideal for applications in automation technology. The non-flush mounting offers flexibility during installation, while the terminal enclosure with screw terminals ensures secure and easy wiring.

The sensor features a protection rating of IP68, making it dust- and waterproof—suitable for outdoor use or in humid, dirty environments. The enclosure is made of PBT/metal, providing high mechanical stability and resistance to chemical influences. The operating voltage ranges from 10 to 60 V DC, and the switching frequency reaches up to 100 Hz, making it suitable for dynamic processes. The ambient temperature can range from -25 to 70 °C, enabling use in a wide variety of industrial scenarios.
