Precision Inductive Sensing for Reliable Metal Detection

The Pepperl+Fuchs NBB20-U1-E2 is a high-performance 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 3-wire DC PNP output, it ensures reliable switching signals across a wide voltage range (10–30 V DC), integrating seamlessly with PLCs and control systems. Reverse polarity and short-circuit protection enhance durability, while a 360° visible yellow LED indicator provides clear feedback on the switching state for easy diagnostics. Boasting 5% hysteresis and a 250 Hz switching frequency, it delivers stable, high-speed detection, ideal for applications like machinery positioning, part counting, and conveyor control where accuracy and consistency are critical.

Robust Construction for Harsh Industrial Environments

Built to withstand extreme conditions, the NBB20-U1-E2 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 washing or submerged environments, while the wide operating temperature range (-25°C to +85°C) suits both freezing warehouses and high-heat production zones. The bidirectional, rotatable sensor head allows flexible alignment in tight spaces, and screw terminal connections (supporting up to 2.5 mm² conductors) enable secure, straightforward installations. Compliance with EN IEC 60947-5-2 and UL listing guarantees safety and reliability in global industrial settings.

Versatile Performance for Seamless System Integration

Designed for adaptability, this inductive sensor offers reduced detection distances for various metals (e.g., aluminum: 0.33, copper: 0.30), enhancing versatility in complex automation setups. The 3-wire configuration simplifies wiring to control units, while its 200 mA operating current and low off-state current (≤0.5 mA) balance energy efficiency with consistent performance. Weighing 225 g and featuring a compact design, it integrates effortlessly into space-constrained machinery. Supported by 3D CAD models and EPLAN data, the NBB20-U1-E2 is ideal for applications ranging from automotive manufacturing and process control to mobile machinery, delivering precision, durability, and ease of use to elevate industrial automation efficiency.
