The Keyence FU-31 Reflective Fiber Unit is engineered for precision detection in compact and challenging setups. With its side-emitting beam configuration, this unit allows for versatile placement where traditional front-facing sensors may not be practical. This makes it especially effective in automated systems where installation space is limited or where detection from the side offers more accurate results.

A key strength of the FU-31 is its ability to detect extremely fine objects, such as gold wires with a diameter as small as 0.005 mm (0.0002″). This ultra-fine detection capability makes it an essential tool for electronics manufacturing, semiconductor processing, and micro-assembly lines, where even the smallest components must be monitored with high precision.

The sensor is built with a 2 m free-cut fiber length that can be customized to the exact application requirement. Its slim √∏1.0 √ó 2 mm diameter ensures minimal installation footprint, and with a minimum bend radius of 10 mm, it provides flexible routing options without compromising optical performance. This adaptability makes it easy to integrate into existing systems without major structural modifications.

In addition to its precision and flexibility, the FU-31 is designed to withstand tough operating conditions. With an operating temperature range from -40°C to +70°C (-40°F to 158°F), it remains highly reliable in both cold storage facilities and heated industrial environments. Despite its ruggedness, the unit is lightweight at just 5 g, reducing mechanical stress when mounted on moving equipment.

Applications of the FU-31 span across industries requiring microscopic detection and space-efficient sensor integration. It is widely used in semiconductor bonding processes, inspection of fine wires, miniature component detection, and high-density electronic assembly lines. By combining precision, durability, and installation versatility, the FU-31 ensures consistent performance in demanding industrial scenarios.

In summary, the Keyence FU-31 Reflective Fiber Unit is a compact yet highly capable solution for manufacturers needing ultra-fine detection in space-constrained environments. With its side-emitting beam, flexible fiber design, and wide temperature tolerance, it offers both precision and adaptability, making it a reliable choice for high-tech production lines.
