New Original Keyence FU-49X Fiber Optic Sensor
1. Product Overview
The FU-49X is a high-precision reflective fiber optic sensor head under Keyence FU series fiber units, designed for stable detection of tiny objects, transparent materials and low-reflectivity workpieces in narrow installation spaces. It is a fiber cable assembly without built-in amplifier, which must be matched with Keyence dedicated fiber optic amplifiers to complete signal emission and receiving. Adopting a slim rectangular sensing head structure, this model features concentrated light beam output, which effectively reduces light scattering interference and realizes high-contrast detection even on dark, matte or semi-transparent targets. As a brand-new original industrial fiber sensor, it supports high-speed detection, strong resistance to ambient light disturbance, and is widely deployed in electronic component positioning, packaging label counting, semiconductor wafer inspection, small plastic part presence judgment, and automated assembly station counting. The integrated bend-resistant fiber core prevents signal loss under frequent cable bending, fitting robotic arm moving equipment and compact automation equipment layouts.
2. Main Functions
- Concentrated reflective light emission: Narrow light spot eliminates false triggering caused by surrounding background reflections.
- Tiny object detection capability: Reliably identify ultra-small targets with minimal reflective surface area.
- Anti-ambient light interference: Special optical filter structure blocks interference from factory fluorescent lamps, LED lighting and sunlight.
- Repeated bending durability: Reinforced fiber sheath maintains stable optical transmission after thousands of bending cycles.
- Universal amplifier compatibility: Matches all mainstream Keyence FS series digital fiber amplifiers for flexible parameter adjustment.
- Short-distance stable detection: Optimized optical path design ensures consistent detection performance within specified sensing range.
- Dust-resistant optical window: Smooth sealed sensing face avoids light attenuation caused by dust and oil accumulation.
- Multi-material adaptability: Works normally on metal, plastic, glass, circuit board, film and matte black workpieces.
- Miniature installation adaption: Ultra-thin sensing head fits limited mounting gaps inside fixtures and small machinery.
- Long service life fiber core: Anti-break internal optical fiber reduces replacement frequency in continuous mass production lines.

Key Technical Features
- Ultra-concentrated beam optical design: The lens at the sensing head converges light into an extremely small spot, greatly improving detection accuracy for micro-components and avoiding background misdetection.
- Reinforced bend-proof fiber structure: Built-in tension-resistant fiber core and anti-crack outer sheath, suitable for dynamic wiring on moving mechanical structures.
- Integrated anti-dust sealed lens: One-piece molded optical window prevents oil mist, metal dust and cutting fluid from penetrating the internal optical path.
- Low light attenuation optical fiber material: High-purity transmission core ensures stable light signal transmission without obvious brightness drop after long-term operation.
- Compact flat sensing head layout: Slim rectangular outline allows side mounting and embedded installation in narrow fixture slots where cylindrical fiber heads cannot be placed.
- Wide temperature adaptation circuit matching: Optical performance remains consistent under drastic workshop temperature fluctuations without sensitivity drift.
- Ambient light filtering coating on lens surface: Special coating filters stray visible light, effectively suppressing false signals from factory surrounding lighting sources.
