DR. JOHANNES HEIDENHAIN GmbH Datasheets for Rotary Encoders

Rotary encoders convert the angular position of a shaft or axle to an analog or digital code. There are two types of rotary encoders, absolute and incremental encoders, which can be controlled by various technologies which include mechanical, optical, magnetic and fiber optic.
