Overview of Optical Mouse Sensor Assembly

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

ment. The ADNS-3000 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, base

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

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