The Pepperl+Fuchs NBB15-U1-A2-V1 is a high-performance inductive proximity sensor designed for precise object detection in industrial automation. Operating on a DC voltage range of 10–30 V, it offers a rated detection distance of 15 mm with a flush mounting design, ensuring stable performance even in confined spaces. The sensor features a PNP output with a 4-wire configuration, supporting both NO/NC switching functions to adapt to diverse control systems. Equipped with four 360° visible LEDs—green for power status and yellow for switching state—it enables easy real-time monitoring from any angle. Its robust construction includes a PA/metal housing with epoxy coating, delivering IP68/IP69K protection against dust, water jets, and harsh environmental conditions.
Built to withstand extreme operational environments, the NBB15-U1-A2-V1 excels in temperatures ranging from -25°C to 85°C, making it suitable for applications in automotive 涂装 lines, heavy machinery, and outdoor installations. The sensor’s rugged design includes reverse polarity and short-circuit protection, ensuring long-term reliability even in voltage-fluctuating or fault-prone setups. With a compact cubic form factor (40 x 40 x 118 mm) and a lightweight 225g construction, it facilitates easy integration into tight mechanical systems. The IP69K rating further guarantees resistance to high-pressure washdowns, critical for industries requiring frequent sanitation, such as food processing or automotive manufacturing.
This sensor’s bidirectional and rotatable sensor head allows flexible alignment for optimal detection angles, enhancing adaptability in complex setups. It supports a switching frequency of up to 200 Hz, ensuring rapid response in high-speed motion control applications. The NBB15-U1-A2-V1 is compatible with standard industrial protocols and features a M12 x 1 4-pin connector for straightforward wiring, reducing installation time. Ideal for material handling, robotic guidance, and conveyor systems, it provides consistent performance across various metallic targets, with reduction factors for aluminum (0.33), copper (0.3), and stainless steel (0.74) ensuring accurate detection regardless of target material. Trusted by industries worldwide, this sensor combines precision, durability, and ease of use to optimize automation processes.
