RSF rotary ring encoder via Heidenhain in North America
A new modular steel tape rotary encoder from RSF Elektronik is now available for measurement applications with diameters of 6 in. (150 mm) to 6 ft (~2 m). Named the MSR 40, this unique and versatile encoder is available in North America through Heidenhain Corp. Applications for this economical ring encoder include rotary tables, telescopes and medical instrumentation. The steel tape of the MSR 40 uses the proven single-field scanning principle with 200arge measurement applications. The novelty of the MSR 40 encoder is that it links the ends of the steel tape together with one of two joining mechanisms, depending upon the application. Measurement through a full 360° is thus possible. The MOR version uses a steel ring tensioning cleat for encoders mounted to a steel surface thus allowing for thermal expansion; the MER version uses a rubber gasket with a low-profile tensioning cleat for other mounting surfaces. Depending on shaft diameter, line counts of up to 20,000 are available on the MSR 40. All versions offer quasi – absolute positioning via distance-coded reference marks or homing via a single reference mark. The MSR 40 is easily mountable and is available in standard and custom sizes. Custom orders are welcomed. For more information on this encoder, RSF Elektronik can be accessed directly via the web site at www.rsf.at.
