The Keyence FU-97S is a diffuse-reflective fiber optic sensor unit designed to deliver precise detection of difficult targets, including transparent or reflective materials. With its optimised detection capability, flexible fiber length, and robust construction, it is particularly suited for industries requiring accurate monitoring of delicate components such as glass substrates, films, or thin panels.

The defining feature of the FU-97S is its diffuse-reflective sensing method. Unlike through-beam or retro-reflective sensors, this fiber unit relies on the light reflected directly from the surface of the target, eliminating the need for a separate reflector or secondary fiber. This simplifies installation while allowing stable detection of targets that might otherwise be challenging, such as transparent glass or glossy surfaces.

The FU-97S is specifically optimised for detecting glass substrates with a thickness of 0.7 mm (0.028″) and a diameter of 200 mm. This capability highlights its suitability for industries such as flat panel display production, semiconductor manufacturing, and electronics assembly, where thin and transparent materials must be detected reliably without errors caused by low reflectivity or light leakage.

To provide flexibility in system design, the FU-97S is supplied with a 2 m fiber unit length, which is free-cut. This means installers can adjust the fiber length to match specific application requirements, ensuring precise routing and minimising excess slack. Such adaptability makes it ideal for integration into both new equipment and retrofit systems.

The unit‚Äö√Ñ√¥s ‚àö‚àè2.2 mm fiber diameter ensures durability while maintaining a slim profile that is easy to install in compact machine spaces. Its minimum bend radius of R40 mm (1.575″) provides flexibility during installation while protecting the fiber from damage or performance degradation, ensuring long-term reliability.

In addition to its mechanical robustness, the FU-97S is lightweight and easy to handle, making it straightforward to integrate into automated systems. Its durability ensures consistent detection performance even in production environments with continuous operation.

Applications for the FU-97S include detecting glass substrates in flat panel production lines, monitoring transparent or reflective parts in electronics manufacturing, and ensuring reliable presence detection in processes involving films, plastics, or delicate sheets. By combining diffuse-reflective technology with high sensitivity, the FU-97S enables accurate detection of objects that are traditionally difficult to sense.

In summary, the Keyence FU-97S is a high-performance diffuse-reflective fiber optic sensor unit designed to detect transparent and reflective objects with precision. With its optimisation for glass substrates, flexible 2 m free-cut fiber length, ‚àö‚àè2.2 mm diameter, and R40 mm bend radius, it provides manufacturers with a versatile and dependable solution. For industries requiring accurate detection of delicate or transparent targets, the FU-97S delivers consistent and reliable results.
