The Pepperl+Fuchs NBB15-U1-A2 is a high-performance inductive proximity sensor designed for precise non-contact detection of metal objects in industrial automation. With a rated operating distance of 15 mm (flush mounting) and a robust 4-wire DC PNP output, it ensures reliable switching signals across a wide voltage range (10–30 V DC). The sensor features reverse polarity and short-circuit protection, minimizing downtime from electrical faults, while a 360° visible yellow LED indicator provides clear feedback on the switching state for easy diagnostics. Its 5% hysteresis and 560 Hz switching frequency enable stable, high-speed detection, making it ideal for applications like machinery positioning, conveyor control, and part counting where accuracy and consistency are critical.
Engineered to thrive in demanding conditions, the NBB15-U1-A2 boasts a durable housing made of PA/metal with an epoxy powder coating, resisting corrosion, impact, and vibration. Its IP68/IP69K protection rating ensures full waterproof and dustproof performance, even in 高压清洗 or submerged environments, while the wide operating temperature range (-25°C to +85°C) suits both freezing warehouses and high-heat production zones. The sensor’s bidirectional, rotatable head allows flexible alignment in tight spaces, and its screw terminal connections (supporting up to 2.5 mm² conductors) enable secure, straightforward installations. Compliance with EN IEC 60947-5-2 and UL listing guarantees safety and reliability across global industrial settings.
Designed for adaptability, this inductive sensor offers complementary switching functions (NO/NC) and reduced detection distances for various metals (e.g., aluminum: 0.33, copper: 0.30), enhancing versatility in complex automation setups. The 4-wire configuration simplifies wiring to PLCs and control units, while its low off-state current (0.5 mA) and 200 mA operating current optimize energy efficiency. Weighing just 225 g and featuring a compact design, it integrates effortlessly into space-constrained machinery. Supported by 3D CAD models and EPLAN data, the NBB15-U1-A2 is ideal for applications ranging from automotive manufacturing and process control to mobile machinery, delivering precision, durability, and ease of use to elevate industrial automation efficiency.
