Product Description

​The Pepperl+Fuchs NBN40-L2-A0-V1 is an inductive proximity sensor designed for non-contact detection of metallic objects. It features a rectangular housing measuring 40 mm × 40 mm × 67 mm, with a rated operating distance of 40 mm, making it suitable for applications requiring reliable object sensing. The sensor operates over a supply voltage range of 10 V DC to 30 V DC and provides a complementary NPN output in a 4-wire configuration. Its robust construction, IP68/IP69K-rated housing, and bidirectional, rotatable sensor head with 360° visibility via four LEDs ensure dependable performance in various industrial environments.
