Product Description

High-Precision Inductive Sensing for Reliable Metal Detection

 

The Pepperl+Fuchs NBB20-U1-A2-T is a robust inductive proximity sensor engineered for precise 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 accurate positioning in compact or complex setups. The 4-wire DC PNP output offers complementary switching (NO/NC configurable), operating seamlessly across a 10–30 V DC range with reverse polarity and pulsing short-circuit protection. Four 360° visible LEDs—green for power and yellow for switching state—provide intuitive real-time diagnostics, while a 440 Hz switching frequency and 5% hysteresis ensure stable performance in high-speed applications like conveyor systems, robotic arm positioning, and part counting.

 

Rugged Design for Extreme Industrial Environments

 

Built to withstand harsh conditions, the NBB20-U1-A2-T features a durable PA/metal housing with an epoxy powder coating, resisting corrosion, impact, and vibration. Its IP68/IP69K protection rating ensures full 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 operates reliably from -25°C to +100°C (ambient) and stores safely at -40°C to +85°C, adapting to extreme temperature variations. Mechanical specifications include a compact 40 x 40 x 118 mm form factor (225 g), screw terminal connections (supporting up to 2.5 mm² conductors with 1.8 Nm torque), and a flush-mountable design for space-efficient installation in vibration-prone machinery.

 

Global Compliance and Versatile System Integration

 

Designed for seamless integration into industrial systems worldwide, the NBB20-U1-A2-T 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 1230 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.
