Absolute Encoders！

 absolute encoders are position encoder feedback devices that report absolute positional information. An absolute encoder generates a unique code for each position. When powered up, these absolute encoders do not require a home cycle even if the shaft was rotated while the power was switched-off. Rounds absolute encoders in this category use optical technology or Hall effect sensing technology to sense positional information.

Absolute encoders come in two categories, single-turn encoders and multi-turn encoders. These absolute encoders provide a variety of resolutions (i.e. 12, 13, 14, 17 bit). The sizes of these absolute encoders are compact to enable easier integration into space constraint applications including medical, security, brushless DC motors, and industrial applications.
