EH Series Encoders

These hollow shaft quadrature output encoders are suitable for use with the OptiTracker to close the loop on stepper control, as a stand alone DRO or for coordinate measurement applications. Standard line resolution is 200. The OptiTracker can be set on ×1, ×2, or ×4 for resolutions up to 800. Standard shaft diameter is .250". 200 count per rev resolution and 400 count per rev resolution are available.
