The Keyence FU-85H Reflective Fiber Unit is designed for high-precision detection in demanding industrial conditions. This model distinguishes itself with its ability to operate in high-temperature environments, handling continuous exposure up to 150°C (302°F). Such resilience makes it suitable for processes where standard fiber units would fail, including applications in metal processing, glass manufacturing, and semiconductor equipment, where heat is a constant factor.

One of the standout attributes of the FU-85H is its exceptional sensitivity to micro-scale targets. The unit is capable of detecting objects as small as a gold wire with a diameter of just 0.005 mm (0.0002″). This capability ensures reliable detection in industries requiring meticulous inspection of tiny components, such as precision electronics, medical device production, and micro-machining. Its performance in detecting ultra-fine objects ensures both efficiency and product quality in advanced manufacturing lines.

The FU-85H also balances durability with flexibility. The fiber unit is 2 meters in length, free-cut, and built with a 2.2 mm √ó 2 fiber diameter, allowing users to adapt the cable length for their specific application. The ability to cut fibers to exact lengths simplifies installation while reducing unnecessary slack, which can be critical in compact machine layouts. This adaptability helps improve equipment integration without compromising on detection performance.

Additionally, the FU-85H’s minimum bend radius of 20 mm allows the unit to be routed through tight installation spaces and around machinery without risking performance degradation or fiber breakage. This compact design makes it particularly valuable for modern automated equipment where space efficiency is paramount.

Overall, the Keyence FU-85H offers a powerful combination of heat resistance, precision detection, flexibility, and durability. It is engineered to excel in environments where extreme conditions and micro-level accuracy are required, making it a trusted choice for industries seeking reliability and precision in fiber optic sensing solutions.
