High-Precision Inductive Sensing for Reliable Metal Detection

The Pepperl+Fuchs NBB20-U1-A2-V1 is a robust inductive proximity sensor designed 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 ensures flexible alignment and accurate positioning in compact or complex setups. The 4-wire DC PNP output offers complementary switching (NO/NC configurable), integrating seamlessly with control systems across a wide voltage range (10–30 V DC). Four 360° visible LEDs—green for power and yellow for switching state—enable quick diagnostics and real-time monitoring. Boasting a 440 Hz switching frequency and 5% hysteresis, it minimizes signal fluctuations, delivering stable performance for high-speed applications like conveyor systems, machinery control, and robotic positioning.

Rugged Construction for Harsh Industrial Environments

Engineered to withstand extreme conditions, the NBB20-U1-A2-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 washdown zones or dusty environments. The sensor operates reliably across a -25°C to +85°C temperature range, making it suitable for both freezing warehouses and high-heat production areas. The flush-mountable design and screw terminal connections (supporting up to 2.5 mm² conductors) simplify installation, while compliance with EN IEC 60947-5-2 and UL listing guarantees safety and global compatibility.

Versatile Performance and Efficient System Integration

This inductive sensor combines adaptability with advanced functionality, offering reduction factors for various metals (aluminum: 0.33, copper: 0.31, stainless steel 304: 0.74) to suit diverse automation needs. Electrical protections include reverse polarity and pulsing short-circuit resistance, enhancing durability and fault tolerance. With a 200 mA nominal operating current and low off-state current (≤0.5 mA), it balances energy efficiency with consistent performance. Weighing 225 g and measuring 40 x 40 x 118 mm, it integrates effortlessly into space-constrained machinery. Ideal for automotive manufacturing, logistics, and process control, the NBB20-U1-A2-V1 delivers precision, ruggedness, and ease of use to optimize industrial automation workflows.
