Exposed linear encoders from HEIDENHAIN are used wherever there is a need for positioning of extremely high accuracy or for a precisely defined motion, for which they always provide very stable scanning signals. However, contamination on the measuring standard or on the scanning reticle can impair these scanning signals. To ensure that these high accuracy requirements can be fulfilled over the encoders’ entire life cycle, HEIDENHAIN has developed a new signal processing ASIC. It first finds application in the new generation of exposed linear encoders with incremental position value acquisition.
The new HEIDENHAIN signal processing ASIC permanently monitors the scanning signal. When scanning signals are subjected to external influences, contamination of the measuring standard, for example, which change the signal, then the new signal processing ASIC practically completely compensates these signal changes and restores the original signal.
