Abstract
A position transducer is provided that includes an encoder disc and at least two detector devices arranged to read at least one track on the encoder disc having low resolution in order to produce position signals. The detector devices each provide position signals to a processing device having a substantial phase difference therebetween. The signal processing device can determine movements of the encoder disc based upon the signals provided by the detector devices and the detector devices can be energized with a low duty cycle during a low power mode.
