Custom Etched Encoder Disk Factory ISO Certified Precision Metal Encoder Disk for Rotary Encoder
 

1. Product Introduction

In industrial automation, servo control and intelligent motion detection systems, the precision of rotary encoders directly determines the accuracy of equipment motion control. Traditional mechanically processed and laser-cut encoder disk generally has inherent defects such as thermal deformation, uneven grating pitch and rough edge burrs, which easily cause signal jitter, pulse loss and detection errors, restricting the upgrading of high-precision automation equipment.

Our high-performance etched encoder disk adopts advanced stress-free photochemical micro-etching technology, which completely avoids the processing defects of traditional technology. The product features ultra-uniform grating slot distribution, vertical and smooth slot walls and excellent overall flatness. It can capture optical signals accurately and stably during high-speed rotation, effectively improving the resolution, repeatability and anti-interference ability of rotary encoders.

Made of high-grade anti-corrosion and fatigue-resistant metal materials, the etched encoder disk maintains stable physical performance in high-speed operation, high temperature and humid industrial environments. As a core precision component of high-end rotary encoders, it is widely used in servo motors, industrial robots, medical precision instruments, CNC machine tools and intelligent logistics equipment, helping global automation enterprises improve product precision and market competitiveness.
