Product Description

The Keyence FU-37 Definite-reflective Fiber Unit is designed for high-precision detection of extremely small objects. Featuring a side beam emitting direction, this fiber unit is ideal for applications requiring accurate and reliable sensing. The fiber unit length is 2 meters, allowing for flexible installation, and the unit has a diameter of ø1.0×2 mm, making it suitable for compact spaces. With a minimum bend radius of R10 mm, the FU-37 can be easily routed in tight areas without compromising performance.

This fiber unit can detect objects as small as a gold wire with a diameter of 0.005 mm, ensuring exceptional sensitivity. It operates reliably in a wide temperature range from -40 to +70 °C, making it suitable for various industrial environments. The FU-37 is lightweight, weighing approximately 6 grams, which simplifies handling and installation.

Key benefits: High precision, side beam emission, flexible installation, and robust environmental resistance. The FU-37 meets the demands of applications requiring precise detection in challenging conditions.
