Pepperl+Fuchs NBB20-U1-E2-T-V1 Inductive Sensor | 20mm, 10-30V DC, IP69K, M30, PNP NO | High-Temp Washdown

High-Precision Inductive Sensing for Reliable Metal Detection

The Pepperl+Fuchs NBB20-U1-E2-T-V1 is a robust inductive proximity sensor engineered for accurate non-contact detection of metal objects in industrial automation. With a 20 mm rated operating distance (flush mounting) and a bidirectional, rotatable sensor head, it enables flexible alignment and precise positioning in compact or complex setups. The 3-wire DC PNP output (normally open) operates seamlessly across a 10–30 V DC range, integrating smoothly with control systems. Four 360° visible LEDs—green for power and yellow for switching state—allow easy real-time diagnostics, while a 440 Hz switching frequency and 5% hysteresis minimize signal fluctuations, ensuring stable performance in high-speed applications like conveyor control, robotic arm positioning, and part counting. Electrical protections against reverse polarity and pulsing short circuits enhance durability in dynamic industrial environments.

Rugged Design for Harsh Industrial Environments

Built to withstand extreme conditions, the NBB20-U1-E2-T-V1 features a durable PA/metal housing with an epoxy powder coating, offering superior resistance to corrosion, impact, and vibration. Its IP68/IP69K protection rating ensures complete dustproof and waterproof performance, capable of enduring high-pressure jet cleaning and prolonged submersion, making it ideal for wet, dusty, or high-contamination zones. The sensor maintains reliable operation across a -25°C to +85°C ambient temperature range (storage: -40°C to +85°C), adapting to both freezing warehouses and high-heat production areas. Mechanical specifications include screw terminal connections (supporting up to 2.5 mm² conductors with 1.2 Nm torque) and a compact 40 x 40 x 118 mm form factor (225 g), simplifying installation in space-constrained or vibration-prone machinery.

Versatile Performance and Global Compliance

Designed for seamless integration into global industrial systems, the NBB20-U1-E2-T-V1 complies with EN IEC 60947-5-2 safety standards and carries certifications like cULus listing and RoHS compliance, with CCC exemption for ≤36 V DC applications. Metal reduction factors (aluminum: 0.33, copper: 0.31, stainless steel 304: 0.74) allow adaptable detection across various metal types, enhancing versatility in automotive manufacturing, logistics, and process control. Functional safety parameters include an MTTFd of 1289 years and a 20-year mission time, ensuring long-term reliability in non-safety-integrated setups. Backed by 3D CAD models and EPLAN data, this sensor combines precision, ruggedness, and ease of use, making it a trusted choice for demanding automation tasks requiring consistent performance and environmental resilience.
