A displacement sensor is an industrial device used to measure linear position or movement of an object and convert it into standard electrical signals such as 4-20mA, 0-10V, or RS485 for automation systems.
A string potentiometer measures displacement using a retractable cable and is ideal for long stroke applications, while linear position sensors (such as potentiometric or magnetostrictive types) are better suited for short to medium range high-precision measurement.
Long stroke displacement sensors are widely used in construction machinery, warehouse logistics systems, industrial automation lines, lifting equipment, and large-scale position monitoring applications.
Common industrial output signals include:4-20mA current output ,0-5V / 0-10V voltage output, RS485 Modbus communication,CAN bus interface
Selection depends on:Measuring range (e.g. 200mm, 2000mm, 3000mm),Required accuracy,Installation environment (temperature, humidity, protection rating), Output signal type, Application industry
High-quality string potentiometers typically support over 300,000 full stroke cycles, depending on load conditions and operating environment.
Yes, customization is available including measuring range, output signal, cable length, mounting style, and protection rating for different industrial applications.
