STL08 Precision Spring-Return Linear Displacement Sensor
The STL08 precision spring-return linear displacement sensor is based on a potentiometric measuring principle, where mechanical displacement is converted into a proportional electrical signal through a sliding wiper moving along a high-precision resistive track. The front-end probe adopts a ball or roller tip with an internal spring mechanism, enabling automatic return for reciprocating motion measurement applications. It supports multiple industrial output signals, including 4–20mA, 0–10V, RS485 Modbus RTU, and CANopen, ensuring easy integration with PLCs, motion controllers, and data acquisition systems. The compact rod-style design allows simple installation and is well-suited for short-stroke, high-frequency dynamic measurement tasks. With high repeatability, strong vibration resistance, and shock durability, the sensor operates reliably in harsh industrial environments ranging from -55°C to +125°C. Its robust aluminum alloy housing and long service life make it ideal for demanding applications. Typical applications include industrial automation systems, hydraulic and pneumatic cylinder position feedback, CNC machine tool positioning, automotive testing systems, and precision engineering measurement equipment where accurate and stable displacement feedback is required.
