Precise Inductive Sensing for Industrial Metal Detection

The Pepperl+Fuchs NBB15-U1-Z2 is a high-reliability inductive proximity sensor engineered for accurate non-contact detection of metal objects in industrial automation. With a 15 mm rated operating distance (flush mounting), it ensures precise positioning in compact or space-constrained setups, supported by a bidirectional, rotatable sensor head for flexible alignment. The 2-wire DC configuration offers NO/NC switching functionality, operating across a wide 5–60 V DC voltage range with reverse polarity and short-circuit protection, enhancing durability in fluctuating power environments. A 400 Hz switching frequency and 5% hysteresis minimize signal oscillations, while two 360° visible yellow LEDs indicate power and switching states for easy diagnostics. Ideal for high-speed applications like conveyor systems, robotic arms, and part counting, it balances precision with robust performance.

Rugged Design for Harsh Industrial Environments

Built to withstand extreme conditions, the NBB15-U1-Z2 features a durable nylon (PA) housing with a metal base and epoxy powder coating, resisting corrosion, impact, and chemical exposure. Its IP68/IP69K protection rating ensures full waterproof and dustproof performance, capable of enduring high-pressure jet cleaning and prolonged submersion, making it suitable for wet, dusty, or high-contamination zones. The sensor maintains stable operation across a -25°C to +85°C ambient temperature range and stores safely at -40°C to +85°C, adapting to harsh industrial climates. Mechanical design highlights include screw terminal connections (supporting up to 2.5 mm² conductors) and a compact 225 g form factor, simplifying installation in vibration-prone machinery.

Versatile Integration and Global Compliance

Designed for seamless automation networking, the NBB15-U1-Z2 complies with EN IEC 60947-5-2 and carries certifications like cULus, CSA, and CCC (for ≤36 V DC), ensuring global safety and compatibility. Metal reduction factors (aluminum: 0.3, copper: 0.3, stainless steel 304: 0.7) enable adaptable detection across various materials, enhancing versatility in automotive, logistics, and process control applications. Functional safety parameters include an MTTFd of 1133 years and a 20-year mission time, reflecting long-term reliability in non-safety-integrated systems. With its robust construction, flexible wiring, and wide operational range, this sensor is a trusted choice for demanding industrial environments requiring precise, durable metal detection.
