🕹An encoder sensor is a device that converts mechanical motion (rotary or linear) into an electrical signal, which is then sent to a control system (like a PLC or computer) to provide feedback on position, speed, direction, and count. This feedback allows for precise monitoring and control of automated systems and machinery. What Is An Optical Encoder? | Optical Encoder Basics Key Functions of an Encoder Sensor The primary function of an encoder is to provide real-time feedback in motion contro
