GENERAL DESCRIPTION
The ZUK is a high performance unit that is ideal for fast revving motor mount
applications. This industrial strength model features the largest thru bore
available in a 2.5" encoder, mounting directly on shafts as large as 1.125" (28
mm.) The injection molded housing is grooved with “cooling fins”, and can take
the extreme heat of the motion control industry.
Radial Runout: 0.005" max
Axial Endplay: +/- 0.050" max
5. STARTING TORQUE: 4.0 oz-in typical (28.24 N-mm) IP66
6. MOMENT OF INERTIA:
The ZUK comes equipped with a 3 point Flex Mount adapting to both 2.25"
and 2.75" motor faces. It is also available with an optional “tether arm”
mounting kit for additional motor compatibility.
This revolutionary encoder can also be adapted to various standard and metric
sized motor shafts by using an accessory sleeve kit, or individual sleeves (Sold
separately).
Electrically the ZUK offers NPN open collector outputs, each limited to 100
mA. The outputs are standard quadrature with index and are also available with
quadrature reverse phasing for the typical motor drive controller application.
The quadrature 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.
7.6 x 10-4 oz-in-sec2
7. MAX ACCELERATION: 1 X 105 rad/sec2
8. ELECTRICAL CONNECTOR: 7-pin MS type connector
