Quality Control
The quality of encoders is directly related to the stability and reliability of industrial automation systems. We have built a full-process quality control system, strictly screening suppliers from raw material procurement to ensure that the performance of core components meets standards; in the production process, we use high-precision equipment and standardized processes, and cooperate with online detection technology for real-time monitoring; in the finished product stage, we conduct rigorous tests such as high and low temperature, electromagnetic compatibility, and life aging to eliminate performance risks. Each encoder has passed multiple quality inspection levels, and its excellent quality has laid a solid foundation for intelligent manufacturing, providing customers with long-term and stable use guarantees.

Application Cases
MK series incremental through-hole encoders, with their stable performance, are suitable for automation control and measurement scenarios, such as precise positioning of robot X-Y worktables; they are also used in printing and packaging, elevators, and motor equipment to assist in speed monitoring and position feedback to ensure operating accuracy.
