Profile

The GHH38 series blind hollow shaft encoder is widely used in the light industry, especially in the control application of the printing and packaging industry. The resolution can reach 3600PPR, which meets the modern light industry requirements of miniaturization, light weight and high precision. The sleeve-type design saves installation space and cost, can adapt to more application environments that restrict installation space, and is a preferred product with higher cost performance.
