Gurley Precision Instruments (GPI) manufactures Optical Encoders for both rotary and linear motion, inconventional, incremental and absolute configurations in GPI’s unique Virtual Absolute technology.  These encoders are used to measure or control position and/or speed in:

                Medical instrumentation

                Electronic manufacturing equipment


                Factory automation

                Graphic arts and printing equipment

                Machine tools

                Radar pedestals

                High speed scanners

                Many other fields


GPI’s self-contained rotary incremental encoders are available in a variety of sizes, from 0.75" diameter with up to 40,960 counts/rev, to a 6" dia model with 3,600,000 counts/rev. An industrial-grade rotary absolute encoder offer resolution up to 217 words/rev. Modular rotary incremental encoders provide a wide choice of size and resolution, while linear encoders come in many mounting configurations, lengths, and accuracy grades. Virtual Absolute™ encoders are available as rotary or linear encoders in both self-contained (housed) and modular configurations.

Gurley specializes in providing customized solutions to specific problems, whether the answer is a low-cost encoder for high production volumes or a very high performance encoder for military or aerospace applications.
