• Manufacturer Part Number: APDS-9003-021
• Description: MINIATURE SURFACE-MOUNT AMBIENT LIGHT PHOTO SENSOR
• Manufacturer: Avago Technologies US Inc.

Specifications of APDS-9003-021

• Package: 6Chip LED

All dimensions are in mm
The window should be placed directly on top of the
photo sensor to achieve better performance and if a flat
window with a light pipe is used, dimension D2 should
be 1.5mm to optimize the performance of APDS-9003.
2.1 Optical Window Material
The material of the window is recommended to be
polycarbonate. The surface finish of the plastic should be
smooth, without any texture.
The recommended plastic material for use as a window is
available from Bayer AG and Bayer Antwerp N. V. (Europe),
Bayer Corp.(USA) and Bayer Polymers Co., Ltd. (Thailand),
as shown in Table 2.
