The SPY1 miniature tie rod linear sensor of the GEFLANG series is mainly used in measurement and control systems for direct and absolute measurement of displacement and length. The maximum working range is 300mm and the high resolution (0.01mm) can provide accurate linear displacement measurement. The structure of the sensor is designed to facilitate installation and disassembly in small places. The internal and external structural surfaces of the sensor have been specially treated to work under high-speed and low-wear conditions. The flexible buffer bearing at the front of the sensor can overcome some slight lateral stress of the transmission rod and ensure the normal operation of the sensor. The process of fixing the conductive material of the sensor and structural design ensures that the sensor can work reliably even under the harshest conditions.
