156 EE-SY169A Photomicrosensor (Reflective)
Photomicrosensor (Reflective)
EE-SY169A
■Dimensions
Note: All units are in millimeters unless otherwise indicated.
■Features
•High-quality model with plastic lenses.
•Highly precise sensing range with a tolerance of ±0.6 mm horizon-
tally and vertically.
•Convergent reflective model with infrared LED.
■Absolute Maximum Ratings (Ta = 25°C)
Note: 1. Refer to the temperature rating chart if the ambient temper-
ature exceeds 25°C.
2. The pulse width is 10 μs maximum with a frequency of
100 Hz.
3. Complete soldering within 10 seconds.
■Electrical and Optical Characteristics (Ta = 25°C)
Note: The letter “d” indicates the distance between the top surface of the sensor and the sensing object.
