Custom Etched Optical Encoder Disc & Rotary Encoder Wheel for Motion Sensing
Xinhaisen specializes in the high-volume production of precision metal encoder discs (also known as code wheels or optical encoders). Using advanced photochemical etching, we produce intricate, burr-free patterns with tight tolerances. These discs are critical for converting mechanical motion into electrical signals in high-precision systems.
Etching (photochemical machining) is a subtractive manufacturing process. A metal sheet is coated with photosensitive resist, exposed to a precise digital pattern, developed, and then chemically dissolved to create complex features. Unlike stamping or laser cutting, etching creates no burrs, no heat-affected zones, and no mechanical stress, making it ideal for thin, delicate encoder discs.
High Precision: Achieves positional accuracy of up to ±0.01mm (customizable).
Fine Lines & Gaps: Minimum line width / space down to 0.02mm (20µm).
Burr-Free & Stress-Free: Smooth edges ensure clean optical readings; no deformation.
Material Versatility: Available in SUS301, SUS304, beryllium copper, nickel-silver, and other alloys.
Custom Patterns: Supports incremental, absolute, or custom coded patterns.
Thickness Range: 0.05mm to 0.4mm (ultra-thin for low inertia).
