Photomicrosensor (Reflective) EE-SY169 Be sure to read Precautions on page 25. Dimensions Features Note: All units are in millimeters unless otherwise indicated. * High-quality model with plastic lenses. * Highly precise sensing range with a tolerance of 0.6 mm horizontally and vertically. * With a red LED sensing dyestuff-type inks. * Limited reflective model. * For lesser LED forward current the EE-SY169B would be a better choice.
