Draw Wire Sensor

Draw wire sensor measures linear movement and displacement using a highly flexible steel cable. The cable drum is attached to the sensor element which provides a proportional output signal based on the measured distance. Our draw wire sensors have compact design with easy and flexible mounting for integration into machinery. They can also be easily customized to fit in high volume applications in OEM.

Our range of draw wire sensors offer quasi-infinite resolution with maximum measurement range of up to 50m. They provide long-term reliability and operational stability even under harsh ambient environment as they are manufactured from high quality components. Users can choose between analog or digital output depending on their measuring requirements.

Draw Wire Measurement Principle

Draw wire displacement sensors measure linear movements using a highly flexible steel cable. The cable drum is attached to a sensor element which provides a proportional output signal.Measurements are performed with high accuracy and high dynamic response, and the measuring drum is axially coupled with a multi-turn potentiometer, an incremental encoder, or an absolute encoder, thus, a linear movement is transformed into a rotary movement and then converted into a resistance change or into countable increments.The use of high quality components guarantees a long life cycle and high operational reliability.
