Wire-acuated encoder is a type of position measurement sensor. Wire-acuated encoder uses a highly flexible steel cable to measure linear positions. The cable drum is attached to a sensor element which provides a proportional output signal. The wire-actuated encoder has the features of sturdy and durable, easy to install, optional various output mode, small installation size, compact structure, large measuring stroke and high precision. Position measurements are performed with high accuracy and high dynamic response.
