GENERAL DESCRIPTION
The ZUJ and ZUL are high performance units that are ideal for fast revving
motor mount applications. The injection molded housing is grooved with
“cooling fins”, and can take the extreme heat of the motion control industry.
The unit comes equipped with a 3.5" to 5.90" B.C. tether arm to mount to a
4.5" motor face.
This revolutionary encoder can also be adapted to various standard and metric
sized motor shafts by using individual sleeves (Sold separately).
Electrically the unit offers line driver outputs, limited to 20 mA per channel.
The outputs are standard quadrature with index and are also available with
reverse phasing for the typical motor drive controller application. The separation
is 90° with output A leading output B for clockwise rotation. Output B leads
output A for the reverse phased output, for clockwise rotation.
