Overview of Optical Mouse Sensor Assembly

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

ment. The ADNS-5095 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-5100-001 lens provides optics for the imaging of the surface as well as

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-xxxx LED is recommended for illumination.
