Gurley Precision Instruments
Absolute and Incremental Rotary Encoders There are two basic types of rotary encoders: absolute and incremental. Absolute rotary encoders provide a coded angle information and avoid time consuming reference measurements or calculation routines in the controller. Incremental rotary encoders provide a square wave or sinusoid output signal and enable counters and PLC to calculate position, speed and distance. Rotary encoders come in four mechanical configurations: modular (kit-type), shaft, blind hollow-shaft and true hollow-shaft...
