Precise Inductive Sensing for Versatile Metal Detection

The Pepperl+Fuchs NBB20-U1-A0-M is a high-precision inductive proximity sensor designed for reliable non-contact detection of metal objects in industrial automation. With a 20 mm rated operating distance (flush mounting), it ensures accurate positioning in compact setups, supported by a bidirectional, rotatable sensor head for flexible alignment. The 4-wire DC NPN output offers both normally open (NO) and normally closed (NC) switching functionality, operating seamlessly across a 10–30 V DC voltage range with reverse polarity and pulsing short-circuit protection. A 400 Hz switching frequency and 5% hysteresis minimize signal fluctuations, while two 360° visible LEDs—green for power and yellow for switching state—enable quick diagnostics. Ideal for high-speed applications like conveyor systems and robotic positioning, its screw terminal connections simplify integration into control systems, balancing precision with operational stability.

Robust Construction for Harsh Industrial Environments

Engineered to withstand demanding conditions, the NBB20-U1-A0-M features a durable PA/metal housing with an epoxy powder coating, resisting corrosion, impact, and vibration. Its IP67 protection rating ensures reliable performance in dusty, wet, or high-pressure washdown environments, while a wide -25°C to +85°C ambient temperature range (storage: -40°C to +85°C) adapts to extreme industrial climates. The sensor’s compact design (118 mm × 40 mm × 40 mm, 225 g) and flush-mountable structure with screw terminals (supporting up to 2.5 mm² conductors) facilitate easy installation in space-constrained or vibration-prone machinery. Metal reduction factors (aluminum: 0.33, copper: 0.31, stainless steel 304: 0.74) enable versatile detection across different materials, enhancing its adaptability in diverse industrial settings.

Compliant Performance and Global System Integration

Designed for global industrial use, the NBB20-U1-A0-M complies with EN IEC 60947-5-2 safety standards and carries certifications like cULus listing and RoHS compliance, with CCC exemption for ≤36 V DC applications. Its functional safety parameters include an MTTFd of 1,289 years and a 20-year mission time, ensuring long-term reliability in non-safety-integrated systems. The sensor’s robust electrical design, including overload protection and low voltage drop (≤2 V), supports stable operation in complex automation networks. Suitable for applications in automotive manufacturing, logistics, and food processing, its combination of precision sensing, rugged construction, and international approvals makes it a trusted choice for critical industrial tasks requiring consistent performance and durability.
