Keyence FS-V31P Fiber Optic Digital Sensor<\/h1>\n
<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The Keyence FS-V31P is a high-performance single-output PNP cable-type main unit digital fiber optic sensor amplifier, specifically engineered for precision non-contact detection in industrial automation scenarios such as electronic component assembly, automotive part manufacturing, packaging quality control, and semiconductor processing. It operates in conjunction with Keyence fiber optic cables, utilizing a 4-element red LED light source to analyze light-intensity variations from the fiber head, enabling accurate detection of diverse objects including metals, plastics, glass, and transparent materials. Equipped with dual digital monitors, multi-stage response times, and automatic sensitivity tracking, it delivers stable and reliable performance even in high-speed production lines with fluctuating ambient light conditions. Its compact DIN-rail-mountable design and user-friendly switch-controlled configuration streamline installation and integration into existing industrial control systems, making it a cost-effective solution for enhancing detection accuracy and production efficiency.<\/div>\n

Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Multi-Material Precision Detection<\/strong>\n
    <\/div>\n

    Works with compatible fiber optic cables to detect small components, irregularly shaped parts, and transparent objects, supporting presence\/absence checks and position verification in confined industrial spaces. The automatic sensitivity tracking function ensures consistent detection even when target surfaces or ambient light conditions change.<\/li>\n

  2. Ultra-Fast Adjustable Response<\/strong>\n
    <\/div>\n

    Offers 6 selectable response time modes (33 \u03bcs to 16 ms) to match the speed requirements of different production lines, from high-speed SMD component placement to slow-moving heavy-part inspection.<\/li>\n

  3. Flexible Output and Timer Control<\/strong>\n
    <\/div>\n

    Features switch-selectable Light-ON\/Dark-ON output modes to adapt to contrast-based detection tasks (e.g., dark parts on light backgrounds or transparent film presence). It also provides 5 programmable timer modes with adjustable duration (0.1 ms to 9999 ms), suitable for counting, batch processing, and sequential control applications.<\/li>\n

  4. Real-Time Dual Digital Monitoring<\/strong>\n
    <\/div>\n

    Integrates dual 7-segment LED displays (green for preset values, red for current detection values) and a 7-step bar LED indicator for excess gain visualization. This allows operators to quickly calibrate parameters and monitor detection status without additional tools.<\/li>\n

  5. Anti-Interference and System Expansion<\/strong>\n
    <\/div>\n

    Supports mutual interference suppression to avoid signal cross-talk when multiple sensors are installed in close proximity (4 units for FINE mode, 8 units for other modes). It can connect up to 16 expansion units, enabling large-scale multi-point detection in complex production environments.<\/li>\n

  6. Remote Calibration and Control<\/strong>\n
    <\/div>\n

    Equips 1 external input interface for remote calibration and signal triggering, facilitating seamless integration with PLCs and HMI systems for automated setup and operation.<\/li>\n<\/ol>\n
