The standout feature of this pull wire displacement sensor is its ultra-long measurement range of 0-5000mm, which fills the market gap for large-stroke position detection at an affordable price point. Unlike laser sensors that may be affected by surface reflectivity, it works reliably on all solid surfaces, including non-reflective materials like concrete and rubber, eliminating measurement errors caused by surface properties. The stainless steel pull wire is coated with a wear-resistant polymer layer, ensuring a service life of over 1 million cycles, which is 30% longer than standard pull wire sensors. Equipped with 0-10V analog output and RS232 digital output, it integrates seamlessly with both old and new industrial control systems, providing flexible data transmission options. Its rugged engineering plastic housing is lightweight yet impact-resistant, and the IP65 protection rating allows it to withstand rain, dust, and minor vibrations in construction or outdoor logistics settings.
This pull wire displacement sensor offers an measurement range of 0-5000mm, suitable for large-scale linear movement monitoring. It has a measurement accuracy of ±0.1mm and a resolution of 0.01mm, balancing precision and cost for industrial-grade applications. The sensor supports dual output signals: 0-10V analog signal for simple integration with PLCs and HMI systems, and RS232 digital signal for high-precision data transmission over short distances. It operates on a wide supply voltage range of 15-36VDC, compatible with most industrial power systems. The response time is 1ms, ensuring real-time data feedback for dynamic applications like hydraulic cylinder control. The pull wire is made of 0.8mm stainless steel with a polymer coating, and the internal spring uses high-tensile carbon steel for consistent retraction force. The housing is made of reinforced ABS engineering plastic, with an IP65 protection grade to resist dust and water spray. The working temperature range is -30℃ to +70℃, and the overall dimensions are 120mm×90mm×60mm, with a net weight of 380g.
This long-stroke pull wire displacement sensor is widely used in industries requiring large-range position monitoring. In construction machinery, it is installed on hydraulic excavators, cranes, and lifting platforms to detect boom extension, arm angle, and platform height, ensuring safe and precise operation. In logistics and warehousing, it is used on automated storage and retrieval systems (AS/RS) to monitor the position of stacker cranes and conveyor belts, optimizing material handling efficiency. In agricultural machinery, it measures the stroke of seed drill adjustment mechanisms and harvester cutting height, improving farming precision. Additionally, it is applied in water conservancy projects to monitor gate opening and closing positions, and in renewable energy systems to track solar panel rotation angles. Its durability and wide operating range make it a reliable choice for all heavy-duty industrial applications involving long linear movements.
