Company Case




As the "intelligent eyes" in industrial production, encoders, with their precise feedback and reliable performance, have become indispensable core components in automated production lines. In the field of mechanical manufacturing, it monitors the spindle speed of machine tools and the position of cutting tools in real time, converts mechanical movements into digital signals, and ensures that the error of cutting and milling accuracy is controlled at the micrometer level. In an automated logistics system, encoders, in conjunction with conveyor belts and robotic arms, accurately measure the displacement distance and Angle of goods, achieving precise sorting and efficient transmission of materials. In addition, the encoder also features strong anti-interference ability and resistance to harsh environments. Even under complex working conditions such as high temperatures and dust, it can still stably output reliable data, providing precise position, speed and Angle information for industrial control systems. This helps enterprises enhance production efficiency, reduce the rate of defective products, and promote the advancement of industrial production towards intelligence and high precision.





In the field of robot applications, encoders are like endowing robots with "sensory nerves", enabling them to precisely perform various complex tasks. It can measure the Angle, position and speed of the robot's joints in real time and accurately, and convert mechanical motion into digital signals to feed back to the control system. When industrial robots perform precise assembly, encoders control the rotation Angle and displacement of the mechanical arm joints with micron-level accuracy to ensure that the components are installed precisely. When service robots navigate in complex environments, encoders work in conjunction with sensors such as lidars to quickly calculate changes in their own postures, helping the robots flexibly avoid obstacles and achieve smooth movement. 

The encoder also has the advantages of high resolution and high reliability, and can output data steadily even under long periods of intense operation. Meanwhile, it has strong anti-interference ability and can operate normally in complex electromagnetic environments, providing a solid guarantee for the stable operation of robots, making robot motion control more intelligent and precise, and becoming a key force driving the continuous innovation of robot technology.
