Optical encoders provide high resolution, high operating speeds and reliability Dynapar offers both mask type and phased array sensing technology. Optical encoders with Dynapar's phased array technology can operate in high shock and vibration environments and are typically rated at 400 G shock and 20 G vibration. Optical encoders work by shining a light source through a patterned disc that is read by a photo-detector. Optical encoders engines can be implemented as incremental or absolute encoders and are available in various mounting styles.
