| ENCODERS KE2109 KE2109-15/18/30 KE2109ch Photo IC KE2109 series is an encorder module in the shape of trans-mission photointerrupter. Red-pin point LED and photo IC of photodiodes with the specific active area are combined. A position detection system of high quality and high reli-ability can be built easily with this module and down sizing is possible.
