STL04 Draw Wire Displacement Sensor
The STL04 Draw Wire Displacement Sensor is a compact and high-reliability linear position sensor designed for industrial automation and motion control systems. It converts mechanical displacement into a proportional electrical signal with stable performance, making it suitable for PLC-based measurement and control applications. It provides a standard measuring range of 150–600 mm with a typical linearity of ±0.3% F.S., and optional high-precision versions up to ±0.1% F.S. The sensor supports multiple industrial output signals including 4–20 mA, 0–5 V, and 0–10 V, ensuring easy integration with most industrial control and data acquisition systems. Powered by ≤24 VDC, the STL04 is optimized for low-voltage industrial environments. Its output behavior follows load-dependent electrical characteristics, ensuring stable and reliable signal transmission in real-world applications. The sensor uses a plastic-coated steel wire rope with a constant tension force of 2–3 N, providing smooth operation, consistent retraction, and long-term measurement stability. The housing is made of anodized aluminum alloy with a black finish, offering excellent resistance to corrosion, dust, and mechanical wear. It operates reliably in temperatures from -10°C to +70°C and can be stored in environments from -25°C to +85°C. Designed for durability, the STL04 supports over 300,000 full stroke cycles, making it suitable for long-term industrial use. With its compact structure, flexible mounting, and robust design, the STL04 is widely used in construction machinery, industrial automation equipment, hydraulic cylinder positioning, material handling systems, and structural displacement monitoring applications.
