Overview of Optical Mouse Sensor Assembly

PixArt Imaging provides an IGES file drawing describing the base plate molding features for lens and PCB alignment.

The ADNS-2080 sensor is designed for mounting on a through-hole PCB, looking down. There is an aperture

stop and features on the package that align to the lens. The ADNS-5110-001 and ADNS-5120-002 lens provides optics

for the imaging of the surface as well as the illumination of the surface at the optimum angle. Features on the lens align

it to the sensor, base plate, and clip with the LED. The LED clip holds the LED in relation to the lens. The LED must be inserted

into the clip and the LED’s leads formed prior to loading on the PCB. The LEDs recommended for illumination include

HSDL-4261 IR LED and HLMP-EG3E Red LED.
