The Keyence FU-87 Reflective Fiber Unit is an advanced fiber-optic sensing component engineered to deliver precision detection in challenging industrial environments. With a design tailored for durability and accuracy, this unit is particularly well-suited for applications where high heat resistance and fine detection capabilities are critical. Its robust construction, compact form factor, and specialized sensing performance make it an essential tool for industries requiring reliable operation under extreme conditions.

A standout feature of the FU-87 is its high-temperature tolerance, rated for environments up to 180°C (356°F). This makes it highly applicable for manufacturing processes involving furnaces, heated tooling, drying equipment, or any environment where standard sensors might degrade. The ability to operate consistently at elevated temperatures ensures long-term reliability, minimizing downtime and replacement costs.

Another defining attribute of the FU-87 is its ultra-fine detection capability. Engineered for high-precision measurement tasks, it can detect gold wire as thin as 0.005 mm in diameter. This level of sensitivity makes it indispensable for microelectronics, semiconductor fabrication, fine metal processing, and other precision-driven fields. Such accuracy allows manufacturers to maintain stringent quality standards, ensuring defects are identified before impacting the final product.

The FU-87 is also designed with versatility in installation. Its 2 m free-cut fiber length and 2.2 mm diameter provide flexibility in routing and mounting, even within restricted spaces. With a minimum bend radius of 35 mm, the fiber can be adapted to different machine layouts without compromising structural integrity. This adaptability enables engineers to optimize sensor placement while maintaining consistent performance.

The reflective sensing design of the FU-87 further enhances its usability. By enabling detection without the need for a separate receiver unit, it simplifies setup and reduces overall system complexity. This is particularly advantageous in compact systems or areas where space constraints prevent the use of larger sensor assemblies. Despite its small size, the FU-87 maintains stable performance across a wide range of detection applications.

In summary, the Keyence FU-87 Reflective Fiber Unit combines high heat resistance, ultra-fine detection, flexible installation, and compact reflective sensing into a single robust package. It is ideally suited for industries such as electronics, semiconductor manufacturing, automotive, and precision machinery, where both durability and accuracy are paramount. By delivering consistent results under demanding conditions, the FU-87 helps manufacturers enhance productivity, reduce errors, and achieve superior quality control.
