**Note:
1.The optical distance (visible light) between the photosensitive surface and the outer surface of the optical window is h = 1.45 ± 0.1 mm;
2.The glass window has a thickness of 0.8 ± 0.02 mm and a refractive index of n = 1.47.**

Caution
1. Pins are connected strictly according to pins illuminating,Load need large than 2kΩ when coupling output DC
2. It should be kept in storage at an environment that has -55~+100℃ and less than 80% relative
humidity,dryness,airiness,no caustic gas.
3. The suitable ESD protecting measures are recommend in storage,transporting and using
4. It's high voltage device,so we need proper design and measure to escape cause damage to human body when
using and operating
