What they do:
Encoders are electronic devices that are best described as “position indicators” that are used to transmit the exact position of a rotary or linear device.
Primary types and how they work:
There are two distinct classes of encoders- rotary and linear. Rotary encoders count revolutions in precise increments usually ranging from 4,000 to over 360,000 individual counts per revolution, through various output stages. Linear encoders regularly measure like increments down to .004” to .000040” resolution.
