Photomicrosensor (Reflective) EE-SY169 Be sure to read Precautions on page 24. ■ 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. Recommended sensing distance = 4.0 mm For lesser LED forward current the EE-SY169B would be a better choice. ■ Absolute Maximum Ratings (Ta = 25°C) Item Symbol Rated value Surface A Emitter Forward current I 40 mA F (see note 1) Two, C0.2 1±0.1 dia. 1±0.1 dia.
