Hollow Shaft Incremental
Optical Encoder The HS22 series
of hollow shaft
incremental encoder
offers application
advantages over
conventional optical
encoders. This
heavy duty unit
is designed
for ease of
installation to a servo
motor, the encoders flexible coupling
fits over the driven motor shaft to provide an accurate, backlash-free
method of attachment.
The mounting method eliminates the need for couplings, sprockets,
or gearing. The integral flex mount provides for a 20-degree angular
adjustment. Through-shaft or blind shaft configurations of the HS22
encoder are available.
Through-shaft units allow for applications where the center of the
encoder must be used for transmission of fluids, cabling, or optics.
Blind shaft units are designed to mate with shaft lengths of 0.50 to
1.50 inch. Standard outputs for both configurations incude: A and B in
quadrature with index and optional commutation signals for brushless
motor control.
