Metal Etching 500cpr 1000cpr Rotary 0.05mm to 0.4mm Optical Encoder Discs


An etched encoder disc is a critical component in motion control systems, providing precise position and speed feedback for a wide range of applications.

Xinhaisen manufacturers encoder discs using advanced etching techniques to create highly accurate patterns that enable encoders to measure rotational movement with exceptional precision.Whether in robotics, industrial automation, or medical devices, etched encoder disc play a vital role in ensuring smooth and reliable operation.



Specifications of Metal Etching Optical Encoder Discs


Using photo chemical etching machining technique, Xinhaisen manufactures custom metallic encoder discs with customer’s drawings. So that we can fabricate metal encoder discs with a wide variety of precise patterns, such as, capacitive encoder disc, optical encoder disc, reflective encoder disc, and magnetic encoder disc etc.
