Displacement sensor with resistance and collector path of conductive plastic on a glassfibre reinforced substrate with internal return spring for direct displacement and tolerance measurements and for continuous position sensing. Features include robust design with high protection class and outstanding accuracy, long life span, easy assembly and a defined electrical measuring range from 75 to 750 mm. The wiper system is mounted on the actuating rod and is coupled free of backlash. This guarantees highest accuracy and very long lifetime. The series can be used in a wide range of applications in mechanical and vehicle engineering industries as well as in automation and robotics, combining remarkable robustness with high accuracy.
