The NB4 Series is a compact, lightweight 6-axis industrial robot designed for space-constrained environments such as electronics factories and machine tool applications. Compared to the first-generation XB4 series, the NB4 is more compact and lighter, making it ideal for high-density production layouts.

With faster running speeds and shorter takt times, combined with industry-leading repeatability of ±0.02 mm, the NB4 delivers both high efficiency and high precision across demanding automation tasks.

The NB4 series features an overall IP67 protection rating, ensuring long-term stability and reliability even in harsh or wet industrial environments. Available in two variants — the NB4h-4/0.58 (580 mm reach) and NB4-4/0.47 (470 mm reach) — the series covers a range of compact-footprint applications.

Both models support floor and ceiling mounting, AC servo drive, integrated air lines (4×Φ4, 5 bar), and 8-channel signal I/O, making them highly versatile for pick-and-place, assembly, and machine tending operations.
