HEIDENHAIN ERM 2203 ring encoder features high tolerance to contamination.

HEIDENHAIN introduced its ERM 2203 ring encoder that is suitable for position measurement applications that require high tolerance to contamination. The encoder retains the 200µm signal period as other current ERM products, though the graduation error has been reduced by approximately 30%. Also, the interpolation error has been cut in half and reversal error has been negated as compared to other ERM encoders. The ERM 2203 series is currently available in the 1Vpp interface with both distance-coded reference marks and single reference marks. Other interfaces will be available, the company says.
