Draw wire Linear Transducer (DWDT) Is a Linear Distance Measuring Transducer for a Travel upto 1000 mm.- Due to Flexibility of the Wire the product is more adorable for application with long stroke measurement.
- DWDT- O has a Optical Incremental encoder attached to one end of the sensor. Which is coupled with a Drum onn which the rope has been wound very precisely. On pulling the Rope the encoder shaft rotates and hence gives the information of the linear motion.
- Since the Rope has been connected on the rope based on the appropriate tention of spring there is no error due to Back lash or play.
- The Resolution of the sensor can be increased or decreased based on the selection of the encoder.

Mounting
- 4 M6 Holes at 59mm X 90.4 mm
- The Mounting of the Sensor should be such that the pulling of the rope is in line with the rope guide.
