Encoders
Encoders for high-precision applications
Metal encoder wheels (codewheels) are designed for high-precision applications in incremental and absolute rotary encoders. The encoder wheels can be produced using any of TMP’s available processes, depending on resolution specifications. The products are highly corrosion resistant and offer superior stability in high-temperature and high-shock environments. TMP also produces optical masks, available in any size or configuration.

Advantages
- Resolution: The electroformed metal encoder wheels are available in resolutions previously unavailable in metal encoder wheel technology. Closer tolerances, greater design capability and increased consistency are all attributes of the TMP proprietary electroforming process.
- Flatness: The TMP proprietary electroforming process reduces the amount of surface tension imposed on the metal encoder wheel, minimizing any possibility of warping.
- Cost: In most applications, metal encoder wheels offer an inexpensive alternative to glass encoder wheels without sacrificing quality.
- Dimensional stability: Temperature and humidity have virtually no impact on the metal encoder wheel. In addition, the TMP metal encoder wheels can be used in high-shock environments with dependable results.
- Corrosion resistance: Metal Encoder Wheels are 100% hard nickel, giving excellent corrosion resistance.
- Multi-layer technology: TMP offers a multi-layer option to maximize the metal encoder wheel’s stability and strength.
