The STL05 series draw wire displacement sensor converts mechanical linear motion into a measurable electrical signal with a proportional linear relationship. When the measured object moves, it pulls the sensor cable, which drives the internal transmission mechanism and rotates the integrated rotary position sensor simultaneously. When the motion reverses, the built-in spring mechanism automatically retracts the cable while maintaining consistent and stable tension throughout the extension and retraction process. As a result, the sensor outputs an electrical signal directly proportional to the cable displacement. The STL05 series features a precision-engineered automatic cable guiding system, ensuring smooth and uniform cable winding. This design significantly improves linear accuracy and extends the overall service life of the sensor. Manufactured with high-quality materials, the sensor housing is made of durable aluminum alloy with an anodized finish, providing excellent resistance to corrosion and contamination. High-strength alloy steel screws are used to enhance mechanical reliability and structural integrity. The sensor is equipped with a premium waterproof aviation connector for secure and stable electrical connections. In addition, the measuring cable is made of plastic-coated steel, improving measurement accuracy while ensuring long-term durability. With its compact design, high accuracy, and reliable performance even in harsh environments, the STL05 series draw wire displacement sensor is widely used in various industrial applications. It is especially valued for its easy installation, flexibility, and dependable operation.
