Pepperl+Fuchs NBB4-12GM50-E2 M50 Proximity Sensor | 4-12mm Range, IP67, IO-Link, Industrial Automation Ready

Precision Engineering for Reliable Metal Detection

The Pepperl+Fuchs NBB4-12GM50-E2 is a high-precision inductive proximity sensor designed for accurate non-contact detection of metallic objects in industrial automation. With a rated detection distance of 4 mm and flush mounting capability, it ensures reliable performance even in confined spaces, ideal for applications requiring precise positioning. Operating on a wide DC voltage range (5–36 V), the 3-wire PNP output (normally open) offers seamless integration with PLCs and control systems, while a switching frequency of up to 2500 Hz enables rapid response in high-speed processes. A yellow LED indicates the switching state for easy diagnostics, and its compact cylindrical design (M12 thread) with a nickel-plated brass housing ensures space-efficient installation in tight mechanical setups.

Robust Durability for Harsh Industrial Environments

Built to withstand extreme conditions, this sensor features an IP68-rated housing, providing full protection against dust, water immersion, and high-pressure washdowns, making it suitable for harsh environments like automotive manufacturing or food processing. It operates reliably across a wide temperature range of -40°C to 85°C, resisting thermal fluctuations and mechanical vibrations. The rugged construction includes reverse polarity, short-circuit, and overvoltage protection, minimizing downtime and enhancing long-term reliability. The 2 m PVC cable with ferruled ends ensures secure connectivity, while the embeddable design eliminates interference from adjacent metals, guaranteeing consistent detection without false triggers.

Versatile Solutions for Automated Systems

The NBB4-12GM50-E2 excels in diverse industrial applications, from conveyor belt monitoring and robotic guidance to material handling and quality control. Its adaptable design supports various metallic targets with defined reduction factors (Al: 0.4, Cu: 0.35, 304 SS: 0.79), ensuring accurate detection across different materials. Compliant with international standards (EN IEC 60947-5-2, UL, CCC) and featuring a lightweight 86 g construction, it simplifies integration into new or retrofitted systems. The sensor’s high repeatability (±2% of rated distance) and low hysteresis (5%) make it a trusted choice for applications demanding precision and consistency, delivering optimal performance in challenging industrial environments.
