MSA Installation Size:

Resolution 0.5um Linear Encoder for Dimensional Measurement

 

Application of Linear Encoder/Scale:

  • It adopts the advanced coating replication technology of glass grafting; it ensures the accuracy of glass pitch: the benchmarks main and auxiliary grafting;
     
  • It adopts the imported electronic components and uses the latest SMT chip mounting technology, it ensures the durability of electronic components and for each linear encorder;
     
  • Scan read system adopts the reliable and durale five-bearing design, it ensures the movement optical induction system smoothly durably;
     
  • It adopts the double anti-oil, high elasticty and anti-aging plastic as dust-seal,it ensures optimum sealing performance and minimal friction force.
     
  • It adopts the precision spring as position controller for the scan read, it ensures the movement of bearing pulley durably and smoothly even in the condition of high-speed;
     
  • It is strictly inspected by testing instrument for each glass, electronic components,dust-seal and snake skin tube,it ensures each linear encorder can calibration of the laser interferometer smoothly;
