My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

These capacitive hollow shaft kit encoders are not limited to a single-turn measurement range: they feature an integrated rotation counter that records each revolution the instrument experiences, even ...
