The Model A37 mini-encoder is a 12-bit single turn absolute rotary encoder with opto-electronic technology. These encoders are used in a wide variety of position sensing applications for the measuring of angles and distances in relatively small envelopes. Mechanical features include a 37-mm diameter aluminum housing, a 3-4 mm 0.125 - 0.25") diameter stainless steel shaft, and precision ball bearings. Output formats include serial, parallel, and multi-plexed versions of Gray code or natural binary.

The Model A37 is one of a family of new low-cost true absolute encoders available from Gurley. Other models include a 19 mm diameter absolute rotary encoder with a resolution of 12 bits and a 58 mm diameter absolute rotary encoder with resolutions of 12, 14, 15 or 16 bits.

Models R112S and R112B optical rotary incremental encoders are designed for light industrial applications that require high resolution in a very small package. Available in either shafted or blind-hollow shaft versions, these encoders are only 12 mm dia x
25 mm long with resolutions up to 8,000 cycles/rev. (32,000 counts/rev.).

Typical applications include:
x-y stages, medical devices, miniature/small instrumentation, compact motors and actuators.
