Mounting and Shaft Connection
Specifications
The shaft can be coupled to the machine using a chain and sprocket, timing pulley and
belt, or a direct in-line shaft-to-shaft coupling.
If a shaft-to-shaft coupling is used, Electro Cam Corp. recommends the use of a flexible
coupling. Flexible couplings available through Electro Cam Corp. are listed on the Rotary
Cam Switch Price List, Lit. #111.
Using a solid coupling with shaft misalignment greater than 0.005" (T.I.R.) may
damage the unit. Because of tolerance stackups, this will require shimming of the
individual unit to its mounting surface.
Output Module Specifications
The EC-3000 Series and the EC-3400 Series units offer plug-in modules for DC, AC, and Reed Relay outputs. One output
module must be purchased for each output desired. For further information, please consult the factory.
