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.

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.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

literature or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.
