Encoders

Jackson Research encoder technologies are interchangeable devices with choices of pole counts and shaft hole sizes. They can be furnished in several grades of precision. All units are designed for harsh environments. Specialized permanent magnets provide stable accurate reliable operation over the entire temperature range. Simple encoder winding alignment during assembly is achieved by rotation of the encoder housing with the encoder magnet fixed to the shaft.

Features include:

  • Phase Angle Resolution to +/- 0.01 Degrees
  • Typical Bandwidths to 10KHz
  • Interchangeable Housings
  • Neutralized Flutter
  • Thermally compensated
  • Near and Far Field Shielding
  • Submersible

These proprietary devices are fully solid state. No sine wave inputs are necessary. Demodulation is no longer required. All Synchro/Resolvers outputs are pure sine waves in real time. Any latency or phase delays are within the device resolution and are not measureable.
