For machine builders and others who require accurate and frictionless measuring systems, Heidenhain Corp. offers a 50-page catalog titled “Exposed Linear Encoders.” The engineering-based publication presents an overview of encoder technologies from the easy-to-install Lida series to the high-resolution Lip series, and details equipment to help a machine produce optimal signal quality. Mounting tips and dimensional and electrical information are provided. Applications for the encoders include metrology systems, linear motors and stages, and medical-related and semiconductor-based machines.
