Modular angle encoders
Modular angle encoders with optical or magnetic scanning come in numerous combinations of a circular scale or scale drum and a scanning head, thus offering the perfectly matched solution for your application. Specs such the interface, accuracy, or diameter can be selected modularly to meet your requirements.
