The A37 Series, manufactured by Gurley Precision Instrument, is a miniature single-turn absolute rotary encoder equipped with an opto/magnetic electronic technology. It has an aluminum housing diameter of 37 mm and stainless steel solid or blind hollow shaft diameter of 3 up to 5 mm. This encoder is designed to provide digital feedback information for any position-sensing applications. The modelA37 mini encoder is a single-turn absolute rotary encoder with opto-electronic technology. This encoder is 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 aluminum housing, a 3 - 5 mm (or 1/8” - 1/4”) dia stainless steel solid or blind hollow shaft, and precision ball bearings.
