Precision Inductive Sensing for Accurate Metal Detection

The Pepperl+Fuchs NBB15-U1-E2 is a high-precision inductive proximity sensor designed for reliable non-contact detection of metal objects in industrial automation. With a rated operating distance of 15 mm (flush mounting), it ensures precise sensing even in compact or complex setups. Equipped with a 3-wire DC PNP output, it offers straightforward integration into control systems, supporting a wide voltage range (10–30 V DC) with reverse polarity and short-circuit protection for robust performance. A visible yellow LED indicator provides clear feedback on the switching state, aiding in quick diagnostics. Its 5% hysteresis and 560 Hz switching frequency minimize signal fluctuations, delivering stable detection for applications like machinery positioning, part counting, and conveyor control where accuracy is critical.

Robust Construction for Harsh Industrial Environments

Engineered to withstand demanding conditions, the NBB15-U1-E2 features a durable housing constructed from PA/metal with an epoxy powder coating, resisting corrosion, impact, and vibration. Its IP68/IP69K protection rating ensures full waterproof and dustproof performance, making it suitable for wet, dusty, or high-pressure cleaning environments. The sensor operates across a wide temperature range (-25°C to +85°C), maintaining stability in extreme heat or cold. The bidirectional, rotatable sensor head allows flexible alignment in tight spaces, while screw terminal connections (supporting up to 2.5 mm² conductors) enable secure and easy installation. Compliance with EN IEC 60947-5-2 and UL listing guarantees safety and reliability in global industrial settings.

Versatile Performance for Seamless Automation Integration

Designed for adaptability, the NBB15-U1-E2 combines reliability with advanced functionality, offering a nominal operating current of 200 mA and low off-state current (≤0.5 mA) for energy efficiency. The sensor’s metal detection characteristics adapt to various materials (e.g., aluminum: 0.33, copper: 0.30 reduction factors), enhancing versatility across applications. Its compact, lightweight design (225 g) and modular structure simplify integration into space-constrained machinery, while 3D CAD models and EPLAN data support streamlined system planning. Ideal for automotive manufacturing, process control, and mobile machinery, this sensor delivers consistent performance, precision, and ease of use, ensuring optimal productivity in industrial automation setups.
