REE interpolators

The REE range of interpolators offer a simple 'plug and play' solution for lower levels of signal interpolation.

The range of REE interpolators increases the resolution of the digital quadrature output signal by a factor of more than 20.

Three models of REE, originally designed for use with Renishaw's range of tape scale encoders, have been validated for use with the RLE.

Features and benefits

  • Easy installation - simple to set up and configure.
  • Automated controls - automated controls for monitoring offset, gain and balance to maintain consistent signals.
  • High resolution quadrature - sub nanometre resolution digital quadrature.

Product information

Please note the REE data sheets referenced above are produced by Renishaw's optical encoder division, and hence do not contain specification data for their use with an RLE system.  They do however contain operating and electrical specification data, as well as dimensional information.
