Aproco also supplies linear sensors besides rotation sensors. The cable sensor requires no precise linear control. It is designed for use in heavy industrial applications: Iron and steel industry, metal processing, wood industry (sawmills, carpentry), etc.
Draw wires offer a simple and cost-efficient solution for measuring linear speed and position (relative and absolute). The linear cable movement is transformed into a rotating movement, which is measured by the sensor. This sensor can be an incremental, absolute or analogue encoder. The maximum distance is 50 meters, and the wire thickness begins at 0.6 mm. The measuring cable is stainless steel and can be coated with polyamide and coiled on a drum if so required.
A pull wire is less costly and more easy to implement than ball screws or rack-and-pinion systems, and forms an effective solution for position and linear speed measurement.
