Absolute rotary encoder A37H

photoelectrichollow-shaftsingle-turn

The model A37H miniature encoder is a single-turn absolute rotary encoder with opto-electric technology that offers up to 21 bit serial output. Optional 1Vp-p sin/cos tracks (1024 cycles/rev) is also available for positioning and speed feedback. 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 37.5mm dia aluminum housing, 8mm max dia hollowshaft, and precision ball bearings.
