Overview / Design Principle:
The RIM Tach® 8500 is the most reliable magnetoresistive digital tachometer found on the market today. Available in either thru-shaft or end-of shaft models, it is specifically designed to provide feedback for AC and DC drive control systems.
Its ductile cast iron enclosure ensures rugged and reliable performance in the harshest environments. Its bearingless design greatly reduces failures and loading on the system. The RIM Tach® 8500 features a magnetized drum that accommodates large (up to 4.5”) thru-shaft or end-of-shaft mounting.
The RIM Tach® 8500 accepts one or two stainless steel sensor modules with patented magnetoresistive technology. Each module generates A and B signals in quadrature, an optional index pulse Z, and each of their complements (A, B, Z). These reliable sensor modules can utilize DC power from +5 to +15 volts, provide transient and noise suppression, and reverse polarity protection. The 8500 high performance tachometer provides resolutions up to 1200 pulses per revolution, which is much higher than traditional encoders.
Its standard mill duty latching connectors are very easy to wire by simply inserting the stripped conductors into the plug and tightening the screw terminals. There is no need to field solder or to struggle with crimp pins. The unit easily mounts on a standard NEMA180 C face (8.5”) and requires no gap adjustments. The sensor module is very simple to change, just remove four screws and slide the new sensor module in place. Finally, an optional shaft grounding brush can be added to the unit to reduce or eliminate motor shaft currents, thereby increrasing motor bearing life.
