Description

The R112 series by Gurley Precision Instruments is a Miniature optical incremental rotary encoder designed for light industrial applications wherein it requires a superior resolution in small packaging. All units have a standard specification of having an LED illumination which can last by about 100,000 hours. Also, it has differential photo detectors designed for signal stability. For its reliability, it uses a single board and surface mount electronics. In addition, a RS-422 is included in the unit which is a differential line driver output for noise immunity.
