Designed with detent and push button switch feature, comes with nuts and washers, ideal for Arduino micro controller use. By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limited. How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors.
