Wire displacement sensors

The wire displacement sensors, also known as wire encoders, wired displacement sensors, wire draw sensors either cable pull sensors, They allow for precise measurement of displacement, position or linear path of a piece, structure or mechanism.

Its operation is based on a retractable steel cable connected to an internal drum. As the element to be measured moves, the cable rotates the sensor mechanism and the incremental encoder converts this linear movement into an electrical signal proportional to the position.

At GUEMISA we have wire displacement sensors for travel distances from 1,000 to 12,000 mm, with different resolutions and output types. The range includes compact models, versions of high resolution up to 0.005 mm/pulse and long-travel wire sensors, with outputs Push-Pull and Line Driver.

Wire encoders for measuring position and linear displacement

Wire encoders are especially suitable when you need to measure a long linear path without installing a ruler, guide, or sensor along the entire path. The sensor body remains fixed while the cable follows the movement of the element to be monitored.

This technology allows position measurements to be taken in industrial applications where other linear displacement systems may be difficult to install due to space, travel distance, or mechanical configuration.

Applications of cable displacement sensors

• Positioning of industrial machinery.
• Measurement of cylinders and actuators.
• Lifting platforms and lifting systems.
• Overhead cranes and handling machinery.
• Test benches and laboratory equipment.
• Automation and process control.
• Measurement of opening and closing of mechanisms.
• Civil works and displacement monitoring.
• Mobile structures and telescopic systems.
• Railway machinery, naval machinery and special vehicles.

How to choose a wire displacement sensor?

To select the right model, the following should be taken into account: maximum travel, resolution, travel speed, and encoder output type.

For compact paths, a wire sensor can be used 1,000 mm. When greater precision is required, versions are available of High resolution for paths up to 5 meters. For longer movements, there are wire encoders with travel distances of 6, 8, 10 and 12 meters.

Consult us, specifying the required route, resolution, and output signal, and we will help you select the right one. wire displacement sensor more suitable for your application.
