Analogue rotary encoders output precise position values as analogue signals. Analogue incremental rotary encoders measure changes in relation to the reference position by counting the pulses with the aid of an optical scanning unit. In contrast to incremental encoders, analogue absolute rotary encoders make do without referencing.

Apart from the current position values for the detection of distance travelled, speed or acceleration, absolute rotary encoders can supply additional measured values. Depending on the application area, we supply analogue rotary encoders with a hollow or solid shaft in standard or custom versions.
