IMPORTANT: To properly install Series M9, a specialized mounting kit must be purchased. Only
one kit is required to install any number of encoders with the same hub bore size.
Kit Part Number: MK M9
Example: Kit for installing encoders with 3.0 mm hub Bore=
Code 4 (from Models Table, above) designating
