High precision and good consistency through strict management of production process, the batch consistency of finished products is excellent! Compared with similar photosensitive devices, the consistency is 2-3 times higher. The minimum accuracy can be controlled to plus or minus 15%; it can meet the control requirements of different lux range values according to customer requirements. The quality of performance determination is stable, the installed defect is less than 10 ppm, high temperature resistance welding, 340 ℃ manual welding, wave peak group and reflow welding performance are all determined. The receiving angle is large, the receiving environment light angle is greater than 120 degrees, and the precise sensing ring.
