New Original Keyence FU-69X Fiber Optic Sensor
1. Product Overview
The FU-69X is a diffuse reflective fiber optic sensing head from Keyence’s FU fiber unit series, engineered for high-precision detection of micro workpieces, dark low-reflectivity objects and small marking features in confined industrial installation spaces. This fiber probe operates paired with Keyence FS series digital fiber amplifiers, as it contains no independent signal processing circuit inside the head unit. Equipped with a narrow focused red light beam, the FU-69X minimizes interference from surrounding background surfaces to eliminate false detection signals. Its ultra-thin flat sensing body supports embedded mounting inside fixtures, automated jigs and miniature machinery equipment. The reinforced bend-resistant fiber cable structure adapts to robotic arms, sliding mechanisms and frequently moving wiring layouts. This brand-new original sensor is widely used in electronics assembly, semiconductor production, packaging inspection, tiny plastic part counting, label edge detection and metal workpiece presence confirmation.
2. Main Functions
- Ultra-narrow focused red light spot detection to distinguish tiny targets against complex background surfaces.
- Strong anti-ambient light performance to resist disturbance from workshop fluorescent lamps, LED floodlights and natural sunlight.
- High flexibility fiber cable with excellent bending endurance for dynamic mechanical motion wiring.
- Universal compatibility with all standard Keyence FS fiber amplifiers for adjustable sensitivity and switching output modes.
- Sealed dust-proof optical lens to prevent light attenuation caused by accumulation of cutting fluid, metal powder and workshop dust.
- Stable detection for diverse materials including matte black plastic, transparent film, PCB boards, aluminum alloy and thin rubber pieces.
- Miniature flat form factor for side mounting and hidden installation in narrow gaps where cylindrical fiber heads cannot fit.
- Consistent optical transmission with low signal attenuation after long-term continuous production operation.
- Compact light emission and receiving integration to maintain stable detection distance without sensitivity drift.
- Wear-resistant outer fiber sheath to extend service life under harsh workshop environmental conditions.

Key Technical Features
- Precision beam convergence optical design: The built-in micro lens compresses light into an ultra-small spot, greatly improving identification accuracy for micro components and thin edges.
- Multi-layer reinforced fiber structure: Tension-resistant internal fiber core and anti-crack outer sheath avoid optical signal breakage during repeated bending and stretching.
- Integrated one-piece sealed optical window: Prevents oil mist, fine dust and coolant from entering the internal optical path to maintain stable light output.
- Anti-interference lens coating: Special optical filter coating filters stray ambient light, effectively suppressing mis-triggering caused by external light sources.
- Slim flat rectangular sensing head: Ultra-low thickness structure supports embedded installation inside narrow fixture slots and compact automation equipment.
- Temperature compensation optical path design: Optical performance remains stable under drastic temperature changes without automatic sensitivity deviation.
- Low-loss high-purity fiber core material: Ensures uniform light signal transmission without brightness decline after long continuous operation.
