Detailed Product Description
Absolute Linear Encoder with 0.0005mm Resolution / 3m High-Speed Optical Linear Scale
Advanced Optical Technology
The ULA/ULB series optical linear scales utilize a single large-size illumination system with independently designed optical lenses, providing more balanced and uniform brightness than conventional LED illumination. This ensures exceptional stability for high-resolution applications.
Key Features & Benefits
  • Single large-size illumination eliminates aging synchronization issues common in multi-LED systems
  • Enhanced reliability and reduced maintenance costs through long-term signal stability
  • Six large-size integrated photodiodes ensure consistent electronic parameters
  • High-quality signal output with superior anti-noise capability and positioning accuracy
  • High-performance double-shield cables for waterproof, stable long-distance transmission
  • Proprietary sinusoidal wave signal subdivision chip for pure hardware processing
  • Fast transmission speeds with incremental A/B signal output up to 2.5MHz
  • Five high-performance bearings ensure excellent repeatability after extended use
  • Aluminum alloy scale frame with anodized surface treatment for harsh environment stability
  • Comprehensive quality control with accuracy testing reports and full traceability
Applications
The ULA/ULB series optical linear scales are widely used on milling machines, lathes, grinding machines, wire EDM equipment, coordinate measuring machines, and automation systems.
