Dynapar NorthStar Rim Tach HS85 Encoder
The Dynapar NorthStar brand RIM Tach HS85 is a mill duty, digital tachometer that accommodates large thru-shaft sizes (up to 4.5 inches or 115mm) and can easily mount to most AC or DC fan cooled motors. The HS85 was created as a solution to roller or sleeve bearing motors with excessive axial and radial play. This digital tachometer is ruggedly designed with steel flanges, heavy duty motor style bearings, and cast iron housing. By virtue of design, the HS85 is more forgiving of older motors which are unable to hold precise tolerances.
