88 EE-SX129 Photomicrosensor (Transmissive)
Photomicrosensor (Transmissive)
EE-SX129
■ Dimensions
Note: All units are in millimeters unless otherwise indicated.
■ Features
• High-resolution model with a 0.2-mm-wide sensing aperture.
• PCB mounting type.
■ 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.
