An encoder is a precision sensing device used in industrial automation to convert mechanical motion—such as position, speed, or rotation—into electrical signals. These signals are then used by control systems like PLCs to monitor and control motion with high accuracy.

Widely used in robotics, CNC machines, elevators, conveyors, packaging systems, and motor control applications, encoders play a key role in ensuring precise positioning and speed feedback. They are commonly available in two types: incremental encoders and absolute encoders, each designed for specific control and feedback requirements.

Known for their high accuracy, reliability, and real-time feedback capability, encoders are essential components in modern automation systems, enabling precise motion control and improved operational efficiency.
