Product Introduction
Our Convergent Reflective Fiber Optic Sensor FD Series is limited-range fiber heads for glass circuit board detection. It restricts detection distance to block background interference, with 5 types: positioning, calibration, position confirmation, general, ultra-small. All models fit FX-500 amplifiers with STD/HYPR two versions, bend-resistant fiber fits stacked & close-background workpiece detection.
Key Benefits
▶Fixed limited detection range: eliminates background light interference for stable detection signals
▶Diverse size categories: positioning, calibration, position confirmation, general, ultra-small to fit different installation space demands
▶Two performance grades: STD & HYPR available to match short and long detection distance requirements

FAQ
Q: What advantages does the range-limited design bring to production testing?
A: It shields reflected light from surrounding frames and conveying platforms, minimizing false detections and improving the overall yield of finished products.
Q: What is the merit of bend-resistant fiber structure?
A: It adapts to narrow mechanical motion gaps, avoids fiber breakage during frequent equipment movement, extends service life and cuts after-sales replacement expenses.
Q: Why is the complete multi-model lineup a highlight of this product?
A: One series covers positioning, calibration and small-space installation demands, customers only need one product line to solve all optical detection needs without purchasing multiple different sensor brands.
