Copper Etching Custom Service Etched Encoder Disc for Optical Sensor
What is a Copper Etched Encoder Disk?
| A Copper Etched Encoder Disk is a high-precision rotary sensing component made from a thin copper sheet using photochemical etching (PCE). It’s used in rotary encoders to accurately measure position, speed, and direction of a rotating shaft. What it looks like
When the disk rotates, sensors read these patterns to generate signals. | |
Except Copper, What Materials We Use
We manufacture metallic encoder disks using high-quality materials to ensure stability, durability, and excellent corrosion resistance:
| Stainless Steel | Aluminum | Nickel | Titanium |
Specifications of Copper Etched Encoder Disk
| Thickness | 0.1mm – 1.0mm |
| Outer Diameter | 5mm – 300mm (customizable) |
| Etch Accuracy | ±0.01mm (According to the thickness) |
| Surface Finish | Matte / Bright / Passivated |
| Pattern Type | Slots, lines, code patterns, or custom designs |
The disk is mounted on a rotating shaft
As it spins, light (optical encoder) or magnetic/electrical sensors detect the etched patterns
The encoder converts these signals into data such as:
Industrial rotary encoders
Servo motors & stepper motors
Robotics and automation systems
CNC machinery
Medical and precision instruments
Aerospace & defense positioning systems
Copper is often chosen because it offers:
Excellent electrical conductivity
Good dimensional stability in thin gauges
Easy, precise etching for fine features
Cost-effective production for complex geometries
It’s especially suitable for photo-etched encoder disks with very fine line widths.
.
Photochemical etching allows:
Burr-free and stress-free edges
Extremely fine features (down to tens of microns)
No tool wear (unlike stamping or laser cutting)
High repeatability for mass production
This is critical for encoder accuracy.
Customization & OEM Service
We support custom metallic encoder disks based on your CAD drawings or design files (DWG, DXF, AI, PDF).
Our engineering team will assist in optimizing your design for etching efficiency and precision.
