KE-2â³22 series are optical encoder which use an infrared LED as a light source, by using in-house products for emitting
components and detecting photo IC, establish both high-quality and high-cost performance, with a digital output and
variation of resolutions, can be used in a wide range of applications. When combined with our âCup diskâ(patent pending),
cost reduction and saving space become possible through a reduction in the number of parts and assembling man-hours.
