The Keyence FU-97P Definite-reflective Fiber Unit is an advanced optical sensing solution engineered for applications that require precise detection of transparent and reflective materials. Unlike standard through-beam or retro-reflective fiber units, the FU-97P utilizes a diffuse-reflective detection principle, making it particularly effective when working with challenging objects such as thin glass substrates, reflective panels, or smooth-surfaced components that often cause false detection in conventional sensors.

One of the defining strengths of the FU-97P lies in its optimization for detecting glass substrates. Its standard detection target is a 200 mm diameter glass with a thickness of 0.7 mm, demonstrating its capability to handle materials that are both highly transparent and prone to light scattering. This feature makes the FU-97P an excellent choice in industries such as electronics, semiconductor manufacturing, and flat-panel display production, where thin glass wafers or protective glass sheets must be reliably detected during assembly and inspection processes.

The sensor is designed with practicality and flexibility in mind. The 2-meter free-cut fiber length allows engineers and technicians to trim the unit to suit specific installation constraints without compromising performance. Its √∏2.2 mm fiber diameter provides a balance of robustness and compactness, enabling integration into tight spaces while maintaining durability. The minimum bend radius of R40 mm ensures that the fiber maintains optical clarity even in curved routing paths, preventing signal degradation and enhancing long-term reliability.

In addition to its structural advantages, the FU-97P delivers consistent performance in environments where reliability is critical. The definite-reflective configuration reduces sensitivity to background interference and ensures accurate detection distances. This stability is vital in high-speed automated production lines where even minor detection errors can lead to costly rework or damage to fragile components.

Overall, the Keyence FU-97P combines high detection accuracy, flexible installation options, and rugged durability to provide a sensor solution capable of handling specialized detection tasks. Its unique ability to detect thin glass substrates makes it indispensable in precision manufacturing environments where conventional sensors may fail. Whether used in inspection systems, automated assembly lines, or quality control applications, the FU-97P ensures that detection processes remain reliable, efficient, and adaptable to the demanding requirements of modern industry.
