F-6HA Small Beam Spot Lens by Keyence
The F-6HA is a small beam spot lens from Keyence. It narrows the light from compatible fiber units into a tight spot. This improves detection accuracy on small targets. It suits space-limited machines and precise positioning tasks.
This lens works with FU-21X, FU-35FZ, FU-35FG, FU-35FA, FU-35TZ, and FU-35TG fiber units. The spot size stays small. The focal distance stays stable. That helps engineers repeat measurements with confidence.
Oiltech Controls supplies tested industrial surplus and refurbished options. Each unit is checked before shipment. A 12-month warranty covers the product. Contact us for current stock and lead time.
