NorthStar RIM Tach Encoder Family
The NorthStar RIM Tach encoder line (formerly Lakeshore encoders) was originally introduced 20 years ago to provide the highest performance encoder solution for large motor and drive control systems in paper and steel mills. The next generation of NorthStar motor tachs offer the most reliable magnetic technology on the market thanks to a large non contacting air gap, active LED indicators with diagnostics, fully encapsulated electronics and field replaceable sensor modules for the RT8 and RT1 models. A high current line driver with active line suppression, reverse polarity and ESD protection is also available for RT models allowing for reliable operation and long cable runs.
