EE-SY169

Photomicrosensor (Reflective) EE-SY169 Be sure to read Precautions on page 25. Dimensions Features High-quality model with plastic lenses. Note: All units are in millimeters unless otherwise indicated. Highly precise sensing range with a tolerance of 0.6 mm horizon- tally 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.
