Etched Encoder Discs Precision Photo Etched Optical Encoder Wheels
Xinhaisen manufactures high-precision etched encoder discs using advanced photo chemical etching technology. Our encoder discs feature extremely fine slot patterns, smooth edges, and excellent dimensional consistency, making them ideal for optical encoders, rotary encoders, motion control systems, and industrial automation equipment.
Unlike stamping or laser cutting, chemical etching produces burr-free and stress-free encoder discs without affecting material properties, ensuring reliable optical signal transmission and long-term performance.
