Custom Etched Encoder Discs for Servo Motors, Robotics, Medical Devices & Automotive Sensors
Encoder discs (code wheels) are precision optical or magnetic components used to convert mechanical motion into electrical signals. Xinhsen’s etched encoder discs offer high uniformity, fine pitch accuracy, and burr‑free edges, ensuring reliable signal output for motion control systems.
Etching (photochemical machining) is a subtractive manufacturing process that uses chemical solutions to selectively remove material from a metal sheet. Key benefits include:
No burrs or mechanical stress
No tool wear
Low‑cost design changes
High precision for complex, fine patterns
High precision – Positioning accuracy up to ±0.01mm, uniformity ±0.03mm
Fine pitch capability – Minimum line width 0.015mm, minimum hole diameter 0.03mm
Burr‑free & stress‑free – No deformation or edge roughness
Wide thickness range – 0.05mm to 0.4mm
Material flexibility – Stainless steel, beryllium copper, brass, nickel‑silver, etc.
Custom patterns – Slots, windows, incremental or absolute code tracks
