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

Product Overview<\/h2>\n
<\/div>\n
The Keyence FS-V31P is a single-output PNP cable-type main unit digital fiber optic sensor amplifier, designed for precision non-contact detection in industrial automation fields like electronic assembly, automotive component production, packaging quality control, and semiconductor processing. It pairs with Keyence fiber optic cables, using a 4-element red LED light source to analyze light-intensity changes from the fiber head for detecting diverse objects, including metals, plastics, glass, and transparent materials. It integrates a dual digital monitor and bar LED indicator for real-time signal visualization, and offers 6 selectable response times, 5 timer modes, automatic sensitivity tracking, and robust ambient light immunity, ensuring stable performance in high-speed, light-fluctuating industrial environmentsKEYENCE CORPORATION OF AMERICA. Its compact DIN-rail-mountable design, switch-controlled setup, and PNP output compatibility simplify integration into existing control systems, making it a reliable solution to enhance detection accuracy and production efficiency in automated linesKEYENCE CORPORATION OF AMERICA.<\/div>\n

Main Functions<\/h2>\n
<\/div>\n
    \n
  1. Multi-Material & Area Detection: Works with fiber optic cables to detect metals, plastics, glass, and transparent objects, enabling presence\/absence checks and position verification of small parts in confined spaces; supports area detection with automatic sensitivity tracking for stable detection of uneven surfacesKEYENCE CORPORATION OF AMERICA.<\/li>\n
  2. Ultra-Fast & Adjustable Response: 6 selectable response times (33 \u03bcs to 16 ms) cater to high-speed production lines, such as rapid SMD component placement and fast-conveyor part inspection\u57fa\u6069\u58eb.<\/li>\n
  3. Light-ON\/Dark-ON Output Flexibility: Switch-selectable output modes adapt to contrast-based detection, like identifying dark components on light backgrounds or transparent object presence\u57fa\u6069\u58eb.<\/li>\n
  4. Versatile Timer Control: 5 timer modes (OFF-delay, ON-delay, one-shot, combined ON\/OFF-delay, combined ON-delay + one-shot) with 0.1 ms to 9,999 ms adjustable duration enable delayed output for counting, batch processing, and sequential production controlKEYENCE CORPORATION OF AMERICA.<\/li>\n
  5. Real-Time Dual Digital Monitoring: Dual 7-segment display shows preset (green 4-digit LED) and current (red 4-digit LED) values simultaneously; current value range 0-64,512, excess gain 0P-999P; bar LED indicates excess gain (85%-115% in 7 steps) for quick calibrationKEYENCE CORPORATION OF AMERICA.<\/li>\n
  6. Hold Function for Peak\/Bottom Tracking: 5 selectable hold function variations display peak and bottom hold values, facilitating stable detection in fluctuating light conditionsKEYENCE CORPORATION OF AMERICA.<\/li>\n
  7. Strong Anti-Interference & Unit Expansion: Mutual interference suppression (4 units for FINE, 8 for other modes) avoids cross-talk; up to 16 expansion units connectable for large-scale sensing setupsKEYENCE CORPORATION OF AMERICA.<\/li>\n<\/ol>\n
