The Pepperl+Fuchs NBB0.8-4M25-E0 is a high-precision inductive proximity sensor engineered for ultra-short-range metal object detection in compact industrial setups. With a cylindrical stainless steel housing (4 mm diameter, 25 mm length) and flush mounting capability, it offers a rated detection distance of 0.8 mm, ideal for applications requiring meticulous positioning, such as micro-component assembly, precision machinery, or robotic guidance. Operating on a 10–30 V DC supply, the 3-wire NPN output (NO function) ensures seamless integration with standard control systems, while an impressively high switching frequency of up to 3000 Hz enables rapid response in high-speed automation processes. A visible yellow LED indicates the switching state, facilitating easy diagnostics and real-time monitoring in space-constrained environments.
Built to endure demanding environments, this sensor features a rugged stainless steel 1.4305 (AISI 303) housing with a PBT sensing face, offering an IP67 protection rating that resists dust, water immersion, and high-pressure sprays. It operates reliably across a wide temperature range of -25°C to 70°C, making it suitable for challenging applications in automotive manufacturing, food processing, or heavy machinery with frequent washdowns. Engineered with reverse polarity and short-circuit protection, it ensures long-term stability and minimizes downtime from electrical faults. The pre-wired 2 m PVC cable with ferruled ends provides secure connectivity, while the compact form factor allows easy installation even in tight, vibration-prone mechanical systems.
The NBB0.8-4M25-E0 excels in applications requiring consistent accuracy and repeatability, such as material handling, quality control in electronics, and adaptive robotic systems. Its non-contact operation reduces wear and tear on moving parts, enhancing system longevity, while the flush-mount design eliminates interference from adjacent metal surfaces for reliable detection without false triggers. The sensor supports diverse metallic targets with defined reduction factors (Al: 0.45, Cu: 0.4, 304 SS: 0.85), ensuring versatile compatibility across industries. Compliant with EN IEC 60947-5-2 and certified by UL and CCC (exempt for ≤36 V), it integrates seamlessly with PLCs and industrial control systems, making it a trusted choice for retrofitting or building advanced automation solutions that demand precision, durability, and ease of use.
