Product Description

The Keyence FU-A10 is a high-precision transmissive fiber optic sensor head designed for detecting minute objects in industrial automation applications. Featuring a 10-mm wide array thrubeam detection area, it offers an optical axis diameter of 11 × 0.3 mm, making it ideal for detecting small opaque materials with a diameter of 0.4 mm. The sensor head is equipped with a 2-meter long fiber optic cable that is free-cuttable (excluding spiral sections), allowing for flexible installation in confined spaces. With an IP67 enclosure rating, it ensures reliable operation in harsh industrial environments.​
