Encoder Incremental Sensor
An incremental rotary encoder working principle is provides cyclical outputs (only) when the encoder is rotated. The incremental rotary encoder is the most widely used of all rotary encoders due to its low cost and ability to provide signals that can be easily interpreted to provide motion related information such as position and velocity.
