Special Capabilities For Unique Situations

Gurley has been a major designer and manufacturer of precise measuring instruments since
1845, and a leading supplier of optical encoders since the early 1950’s. We have a full line of
standard products, most of which are shown in this catalog. However, we do add products
regularly, so please call (800) 759-1844 or visit www.gurley.com if you do not see what you
are looking for.

Although we have many standard encoders, our real strength has always been our
willingness and ability to provide solutions to special customer problems, whether it
involves modifying an existing design or starting with a clean piece of paper. We enjoy a
well-deserved reputation as a responsive and responsible business partner, and we
look forward to adding your name to our long list of satisfied customers.

In the product descriptions that follow, all incremental encoders are available with an index
(once per rev) signal that is fully functional up to the maximum frequency response. Many of
the maximum resolutions listed are after 4X quadrature evaluation in the user’s electronics.
For complete specifications, please refer to the technical datasheet or call for free
application assistance.

Warranty
Gurley Precision Instruments offers a limited warranty against defects in material and
workmanship for a period of one year from the date of shipment.

Accessories

Rotary Encoders

For your convenience, Gurley offers a variety of encoder accessories such as cable
assemblies, shaft couplings, mounting cleats, and counter/displays. Please consult
factory for more information.

A Few Words About Resolution
The term “cycles/rev” refers to quadrature output. By utilizing well-known techniques
for quadrature decoding, the user can readily obtain four times as many counts, or
measuring steps, per revolution as the number of cycles. For more information, please
