Pepperl+Fuchs NBB20-U1-E2-C-V1 Inductive Sensor | 20mm Range, 10-30V DC, IP69K, M30, PNP NO | Washdown Areas

Precise Inductive Sensing for Reliable Metal Detection

The Pepperl+Fuchs NBB20-U1-E2-C-V1 is a high-performance inductive proximity sensor designed for accurate non-contact detection of metal objects in industrial automation. With a 20 mm rated operating distance (flush mounting), it ensures precise positioning even in compact setups, supported by a bidirectional, rotatable sensor head for flexible alignment. The 3-wire DC PNP output (normally open) operates across 10–30 V DC, integrating seamlessly with control systems, while four 360° visible LEDs—green for power and yellow for switching state—enable easy diagnostics. Boasting a 440 Hz switching frequency and 5% hysteresis, it minimizes signal fluctuations, delivering stable performance for high-speed applications like conveyor control, robotic positioning, and part counting. Its robust design includes reverse polarity and pulsing short-circuit protection, enhancing durability in demanding workflows.

Rugged Construction for Harsh Industrial Environments

Engineered to thrive in extreme conditions, the NBB20-U1-E2-C-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, capable of withstanding high-pressure washdowns and dusty environments. The sensor maintains reliable operation across a -25°C to +85°C ambient temperature range and stores safely at -40°C to +85°C, adapting to both freezing and high-heat industrial zones. Mechanical specifications include screw terminal connections (supporting up to 2.5 mm² conductors) and a compact 40 x 40 x 118 mm form factor (225 g), simplifying installation in space-constrained machinery. Its flush-mountable design and rugged build make it ideal for applications in automotive manufacturing, metalworking, and logistics.

Compliant Performance and Versatile System Integration

Designed for global industrial use, the NBB20-U1-E2-C-V1 complies with EN IEC 60947-5-2 safety standards and carries certifications like UL 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 different materials, enhancing versatility in complex automation setups. Functional safety parameters include an MTTFd of 1289 years and a 20-year mission time, ensuring long-term reliability in non-safety-integrated systems. Supported by 3D CAD models and EPLAN data, this sensor enables seamless integration into control systems, making it a trusted choice for applications requiring precision, durability, and ease of installation, from conveyor networks to process control machinery.
