Stroke detection unit is the core component for precise control of hydraulic cylinders. Wujin Hydraulic's independently developed active magnetic detection stroke sensing technology, equipped with high-performance data acquisition and processing chips, delivers higher sensitivity, better temperature adaptability and frequency response than traditional Hall sensors. By designing a special structure on the piston rod surface, the sensor obtains accurate real-time position information when approaching, realizing high-precision, high-reliability monitoring of cylinder stroke.
Since the launch of the first-generation product in 2008, we have continuously iterated and launched incremental, absolute and miniaturized series. In 2012, we successfully developed the world's first stroke detection device with power-off memory function, leading the industry with our technical strength.
