Encoders turn mechanical motion into an electrical signal that is used by the control system to monitor specific parameters of the application and make adjustments if necessary to maintain the machine operating as desired.
Transducers (such as optical or magnetic encoders) sense position or orientation for use as a reference or active feedback to control position: A rotary encoder converts rotary position to an analog (e.g., analog quadrature) or digital (e.g., digital quadrature, 32-bit parallel, or USB) electronic signal. A linear encoder similarly converts linear position to an electronic signal. Such encoders can be either absolute or incremental.
