Features of draw-wire linear position sensors！

This draw-wire linear position sensors（string sensor， string pots，cable extenstion sensor） has certain features which can provide benefits to the user. It allows a short to long range capability from a minimal sensor footprint with 100 to 5000mm measuring range. It also suitable for a wide range of industrial applications since it is rugged, robust and has very compact design. Roundss have the draw-wire linear position sensors from the range of 50mm to 10000mm.RLD40，RLD50,RLD63,RLD78,RLD95 are the regular models required by customers.

The choice of interface signals for this sensor can be either analogue or digital outputs. Analogue connection is chosen for high volume production applications while digital connection is used where the relative position displacement should be measured. Besides, the sensor suited to hostile conditions since it is protected to IP65.

Other additional feature is the measuring wire can be deflected using deflection pulleys. Because of its benefits, draw-wire sensor is widely used in medical engineering applications such as position measurement on X-ray machines, monitoring of training exercises on rehabilitation and therapy machines, angle measurement in SoloAssist, position measurement in computer tomography and positioning of operating tables. In logistics applications, the sensor is used in displacement measurement on slag transporter, positioning of catering trucks at Airbus A380 and lift-height measurement in fork-lift trucks. The sensor also widely used in other variety applications such as automotive, aerospace, power plant engineering and etc.
