The Keyence FU-38V Definite-Reflective Fiber Unit is a specialized sensor accessory engineered to deliver high precision, durability, and flexibility in industrial automation and inspection tasks. Designed to work seamlessly with Keyence fiber optic amplifiers, this fiber unit provides outstanding detection capabilities, particularly in applications requiring the identification of fine or delicate objects.

A key advantage of the FU-38V is its ability to detect extremely small objects, such as copper wire with a diameter as thin as 0.08 mm. This makes it an excellent choice for industries such as electronics, semiconductor manufacturing, and fine machinery production, where micro-level accuracy is essential. Its definite-reflective design ensures stable detection by minimizing variations in target distance, allowing for consistent performance in precision applications.

The fiber unit is designed for installation flexibility, featuring a flat beam emitting direction that makes it suitable for tight spaces or specialized mounting orientations. With a minimum bend radius of just 10 mm, the fiber can be routed easily through compact machinery layouts without compromising performance or risking fiber damage. This flexibility supports integration into modern, space-efficient production systems.

Another benefit of the FU-38V is its free-cut 2-meter fiber length, which allows users to trim the fiber to match specific installation requirements. This reduces excess fiber, ensures neat and efficient setups, and provides versatility for a wide range of machine designs and production line configurations.

Durability is central to the FU-38V’s construction. Weighing only 5 g, it is lightweight yet built for reliability, with an operating temperature range from -40 to +70 °C. This wide environmental resistance makes it suitable for harsh conditions, including both high-heat industrial processes and low-temperature environments. Its robust design ensures stable long-term operation, reducing downtime and maintenance needs.

In summary, the Keyence FU-38V Definite-Reflective Fiber Unit is a precision-focused, adaptable, and reliable sensing solution. By combining ultra-fine detection capability with flexible installation, customizable fiber length, and rugged environmental resistance, it empowers manufacturers to achieve consistent accuracy and efficiency in demanding production environments. Whether used for micro-wire detection, component verification, or precision inspection, the FU-38V delivers performance that enhances productivity and reliability.
