Keyence FS-V31P Fiber Optic Digital Sensor
Product Overview
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.
Main Functions
- 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.
- Ultra-Fast & Adjustable Response: 6 selectable response times (33 μs to 16 ms) cater to high-speed production lines, such as rapid SMD component placement and fast-conveyor part inspection基恩士.
- 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基恩士.
- 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.
- 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.
- 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.
- 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.
