Overview of Optical Mouse Sensor Assembly

PixArt Imaging provides an IGES file drawing de-

scribing the base plate molding features for lens and PCB

alignment.

The ADNS-5050 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.

Figure 3. Recommended PCB mechanical cutouts and spacing.

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 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 HLMP-EG3E-xxxxx LED is recommended for illumina-

tion.
