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.
There are two types of mechanical configurations for optical encoders: rotary encoders and linear encoders. Optical rotary encoders are most commonly found in motion control systems while linear encoders are used more specifically for linear-positioning applications such as piston or actuator monitoring systems.ncremental optical encoders are the simplest and most commonly used. The encoder provides information about the instantaneous position of a rotating shaft by producing one square wave cycle per increment of shaft movement.
