The Pepperl+Fuchs NBB15-U1-A2-T-V1 is a high-precision inductive proximity sensor engineered for reliable non-contact metal detection in industrial automation. Featuring a bidirectional and rotatable sensor head, it allows flexible alignment in tight or complex setups, ensuring accurate detection at its rated 15 mm operating distance (flush mounting). Equipped with four 360° visible LEDs—green for power status and yellow for switching state—it enables easy diagnostics and real-time monitoring. The 4-wire DC PNP output offers complementary switching (NO/NC), operating seamlessly within a 10–30 V DC range with reverse polarity and pulsing short-circuit protection. With a 5% hysteresis and 560 Hz switching frequency, it delivers stable, high-speed performance, ideal for precision tasks like machinery positioning, part counting, and conveyor control.
Built to withstand extreme conditions, the NBB15-U1-A2-T-V1 features a durable PA/metal housing with an epoxy powder coating, resisting corrosion, impact, and vibration. Its IP68/IP69K protection rating ensures full waterproof and dustproof performance, even in high-pressure 清洗 or submerged environments, while the wide operating temperature range (-25°C to +85°C) suits both freezing warehouses and high-heat production zones. The sensor’s screw terminal connections accommodate up to 2.5 mm² conductors, enabling secure installations, and its lightweight design (225 g) simplifies integration into compact machinery. Compliance with EN IEC 60947-5-2 and UL listing guarantees safety and reliability across global industrial applications.
Designed for seamless system integration, this inductive sensor offers reduced detection distances for various metals (e.g., aluminum: 0.33, copper: 0.30), enhancing adaptability in diverse setups. The 4-wire configuration supports straightforward wiring to PLCs and control units, while its low off-state current (0.5 mA) and 200 mA operating current optimize energy efficiency. Additional features include a quick startup time (80 ms) and modular design with available 3D CAD models and EPLAN data for streamlined installation. Ideal for automotive manufacturing, process automation, and mobile machinery, the NBB15-U1-A2-T-V1 combines precision, durability, and ease of use, ensuring consistent performance in even the most demanding industrial environments.
