Precision Inductive Sensing with Programmable Flexibility

The Pepperl+Fuchs NBB20-L2-B3-V1 is a high-performance inductive proximity sensor designed for precise non-contact detection of metal objects in industrial automation. Featuring a 20 mm rated operating distance (flush mounting) and a bidirectional, rotatable sensor head, it enables flexible alignment in tight spaces for accurate positioning. The sensor offers NO/NC programmable switching via its 2-wire AS-Interface output (V2.1), ensuring seamless integration with modern control systems across a voltage range of 26.5–31.9 V DC. Equipped with dual LED indicators—green for power, yellow for switching state, and red for errors—it provides clear diagnostic feedback. With a 150 Hz switching frequency and 5% hysteresis, it delivers stable, high-speed detection, ideal for applications requiring reliable signal transmission, such as conveyor systems, robotic arms, and machinery control.

Rugged Design for Harsh Industrial Environments

Engineered to thrive in challenging conditions, the NBB20-L2-B3-V1 boasts a durable PA housing and sensing face, resisting corrosion, impact, and chemical exposure. Its IP69K protection rating ensures full resistance to high-pressure jet cleaning and dust, making it suitable for wet, dirty, or high-contamination environments. The sensor maintains consistent performance across a wide ambient temperature range (-25°C to +70°C) and stores safely at -40°C to +85°C, adapting to extreme industrial climates. The M12 x 1 4-pin connector enables quick, secure wiring, while its lightweight design (130 g) and flush-mountable structure simplify installation in compact or crowded machinery setups.

Seamless Integration and Global Compliance

Designed for advanced automation networks, this sensor complies with AS-Interface V2.1 specifications, ensuring compatibility with modern industrial communication systems. It features reverse polarity protection and low no-load current (≤40 mA), enhancing energy efficiency and fault tolerance. Certified to EN IEC 60947-5-2 and listed by UL/CSA, it meets global safety standards for general-purpose industrial use, with CCC exemption for ≤36 V DC applications. The sensor’s MTTFd of 1330 years and 20-year mission time reflect its long-term reliability, while 0% diagnostic coverage suits non-safety-integrated setups. Ideal for automotive manufacturing, logistics, and process control, the NBB20-L2-B3-V1 combines precision, durability, and ease of integration to optimize industrial automation workflows.
