Keyence FU-35FG Fiber Optic Sensor<\/h1>\n
<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The Keyence FU-35FG is a compact, high-precision coaxial reflective fiber optic sensor unit designed for seamless integration with Keyence fiber optic amplifiers (e.g., FS-V31P, FS-N41P) in industrial automation. It features an M3-sized straight sensor head with a coaxial detection arrangement, making it ideal for confined-space applications requiring non-contact, ultra-precise object detection, such as inspecting micro-electronic components, semiconductor leads, and fine mechanical parts\u57fa\u6069\u58eb. The 1-meter free-cut fiber cable allows flexible installation customization, while its robust stainless steel spiral sleeve and durable polymer jacket ensure reliable performance in harsh industrial environments with extreme temperatures, vibration, and minor chemical exposure\u57fa\u6069\u58eb. This sensor unit excels in scenarios demanding high accuracy and space efficiency, providing consistent detection results for quality control and process optimization in electronics, semiconductor, and automotive manufacturing\u57fa\u6069\u58eb.<\/div>\n

Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Ultra-Precise Micro-Object Detection<\/strong>\n
    <\/div>\n

    It can detect objects as small as a 0.005 mm diameter gold wire under optimal detection distance and sensitivity settings, making it suitable for inspecting semiconductor bonding wires, fine-pitch electronic components, and micro-mechanical parts in precision manufacturing\u57fa\u6069\u58eb.<\/li>\n

  2. Coaxial Reflective Detection<\/strong>\n
    <\/div>\n

    The coaxial design ensures that the light emission and reception paths are aligned, minimizing signal loss and enhancing detection stability. This function is crucial for applications requiring consistent detection of small, reflective, or transparent objects, such as checking for the presence of tiny glass components or verifying the position of miniature metal parts\u57fa\u6069\u58eb.<\/li>\n

  3. Flexible Installation and Cable Customization<\/strong>\n
    <\/div>\n

    The 1-meter fiber cable is free-cut, allowing users to trim it to the exact length needed for their setup, reducing cable clutter and optimizing sensor layout. The M3-sized sensor head and R10 mm minimum bend radius enable installation in tight spaces and around mechanical fixtures, providing flexibility in complex automation systems\u57fa\u6069\u58eb.<\/li>\n

  4. Harsh Environment Adaptability<\/strong>\n
    <\/div>\n

    It operates stably within a temperature range of -40\u00b0C to +50\u00b0C, suitable for high-temperature manufacturing processes, cold storage inspection lines, and outdoor industrial applications. The stainless steel spiral sleeve and durable polymer cable jacket resist mechanical wear, vibration, and minor chemical exposure, ensuring long-term reliability\u57fa\u6069\u58eb.<\/li>\n

  5. Seamless Amplifier Compatibility and System Integration<\/strong>\n
    <\/div>\n

    When paired with Keyence fiber optic amplifiers, it converts light-intensity variations into digital signals that can be easily integrated with PLCs, HMIs, and other industrial control systems. It supports mutual interference suppression when multiple sensors are deployed in close proximity, maintaining signal integrity in high-density detection setupsKEYENCE CORPORATION OF AMERICA.<\/li>\n<\/ol>\n
