The R137 by Gurley Precision Instruments is a Compact optical incremental rotary encoder for industrial grade applications wherein it requires a superior resolution in small packaging. The whole unit comes with a diameter of 37 mm which has a cable that is shielded and sealed to IP66. All units have a standard specification of having an LED illumination which can last by about 100,000 hours. Also, its bearings are sealed for contamination. A RS-422 is included in the unit which is a differential line driver output for noise immunity. Plus, it has an optional fault detection signal designed for resolutions of 360k and 720k counts/rev.
