Overview of Optical Mouse Sensor Assembly
Avago Technologies provides an IGES file drawing de scribing the base plate molding features for lens and PCB alignment.
The ADNS-2700 sensor is designed for mounting on a through-hole PCB. There is an aperture stop and features on the
package that align to the lens. The ADNS-5100-xxx 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 ADNS-5200 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 HLMP-EG3E LED is recommended for illumination.
