The EX-20 series ultra-compact Photoelectric Sensor with amplifier built-in. The sensor incorporates a sensitivity adjuster in spite of its miniature size. The beam-receiving photodiode and the A/D conversion circuit have been fabricated on a single chip optical IC (full custom). Hence, in spite of its miniature size, it has a performance and reliability which is equal to or better than the conventional product. The EX-20 series achieves long distance sensing (thru-beam type - 2m 6.562ft, retroreflective type - 200mm 7.874 inch (when using the attached reflector), diffuse reflective type - 160mm 6.299 inch). A red LED dot light source is used, the red beam spot is clear even at a far place, so that alignment and confirmation of sensing position is easy.
