NBB20-U1K-E2-3G-3D Inductive Sensor 20mm Range IP67 M30 Thread Pepperl+Fuchs

Compact Design for Versatile Industrial Integration

The Pepperl+Fuchs NBB20-U1K-E2-3G-3D is a high-performance inductive proximity sensor engineered for precise non-contact detection of metallic objects in diverse industrial setups. Its compact form factor and threaded cylindrical housing (M18 design) enable flexible installation, even in space-constrained environments, while the rotatable sensing head allows 360° adjustment to optimize detection angles. The 3-wire DC PNP output (NO/NC complementary) ensures seamless integration with standard control systems, operating across a wide 10–30 V DC voltage range. A visible LED indicator provides clear feedback on power status and switching events, enhancing operational monitoring. Weighing just 90 g and equipped with a quick-mount bracket, this sensor simplifies setup in machinery, conveyors, or robotic arms where agility and space efficiency are critical.

Reliable Sensing with Robust Technical Specifications

Designed for consistent performance, the NBB20-U1K-E2-3G-3D offers an 20 mm rated sensing distance (flush mounting) with a 5% hysteresis to minimize signal fluctuations from vibration or material variance. Its inductive technology ensures stable detection of ferrous and non-ferrous metals, supported by reduction factors for materials like aluminum (0.33) and stainless steel (0.74) to guide target selection. The sensor withstands harsh conditions with an IP67 rating, protecting against dust and water immersion, while its operating temperature range of -25°C to 70°C ensures reliability in challenging environments. Safety features include reverse polarity and short-circuit protection, safeguarding both the sensor and connected equipment during operation. A switching frequency of 400 Hz makes it suitable for high-speed applications, such as automated sorting or precision positioning.

Durability and Compliance for Demanding Applications

The NBB20-U1K-E2-3G-3D meets international standards (EN/IEC 60947-5-2) and carries certifications like CE and UL, ensuring compatibility with global automation systems. Its polyamide (PA) housing and nickel-plated brass sensing face resist corrosion and mechanical stress, ideal for use in manufacturing, logistics, or process control industries. The sensor’s flush-mount design reduces interference from adjacent metal surfaces, critical for dense machine layouts, while its M12 connector ensures secure, standardized wiring. With a proven MTTFd exceeding 1000 years and a mission time of 20 years, it delivers long-term reliability in critical applications, such as AGV navigation, conveyor monitoring, or robotic arm feedback. Trusted by industries worldwide, this sensor embodies Pepperl+Fuchs’ commitment to precision, durability, and innovation in industrial sensing solutions.
