For a hollow-shaft encoder that can withstand high mechanical loads and harsh operating environments, check out our A02H. This incremental encoder is compact with an installation depth of just 49 mm and support for shafts up to 42 mm. But it’s the ruggedness of this IP 65-rated encoder that really makes it stand out. It offers a dual-bearing design that lets it tolerate high axial, radial, shock and vibration loads.
