Draw Wire Displacement Sensor, 1000~50000mm

A draw wire displacement sensor is a device used to measure linear displacement. It converts mechanical movement into an electrical signal by means of a retractable wire that drives an internal drum and sensor element. It combines the advantages of angular sensors and linear displacement sensors, featuring a compact structure, small installation size, high accuracy, and a wide measuring range.

Draw wire displacement sensors are widely used in industrial automation and engineering applications, such as position and stroke measurement of industrial equipment, displacement and height monitoring in construction machinery (cranes, excavators, lifting platforms), position feedback in warehousing and logistics systems, displacement measurement in metallurgical and mining equipment, motion control in robots and intelligent systems, and structural displacement monitoring in bridges, tunnels, and other civil engineering projects.

A draw wire displacement sensor works by using the extension and retraction of a wire to drive an internal drum to rotate. This mechanical movement is converted into an angular change, which is then transformed into an electrical signal by an internal encoder or potentiometer, enabling precise measurement of linear displacement.
