Precision Etched Encoder Disc Stainless Steel Optical Rotary Encoder
Precision etched encoder discs are widely used in optical encoders, rotary encoders, incremental encoders and absolute encoders. Photo chemical etching produces burr-free code patterns with extremely fine line widths and excellent dimensional accuracy, making it ideal for high-performance motion control systems.
Encoder Discs Overview
High-precision etched encoder discs for optical encoders, rotary encoders, and motion control systems. Custom stainless steel encoder wheels with burr-free edges and excellent dimensional accuracy.
Compared with laser cutting or stamping, photo chemical etching creates stress-free, burr-free encoder discs without affecting material flatness. Fine features as small as 10 μm can be produced while maintaining excellent repeatability for precision encoder applications.
Encoder Discs Features
1.Ultra-High Precision: Capable of producing extremely fine lines and micro-holes.
2.Burr-Free & Stress-Free: The etching process eliminates mechanical stresses and burrs, ensuring smooth edges and accurate performance.
3.No Material Hardness Change: Unlike stamping or laser cutting, etching does not affect the base metal's temper or magnetic properties.
4.Rapid Prototyping & Production: Fast turnaround from design to mass production.
5.Material Versatility: Can be etched from various alloys.
- High precision optical encoder patterns
- Burr-free photo chemical machining
