surface at the optimum angle. Features on the lens

align it to the sensor, base plate, and clip with the LED.

The lens also has a large round flange to provide a long

creepage path for any ESD events that occur at the

opening of the base plate.

The ADNS-2220-001 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 clip

interlocks the sensor to the lens, and through the lens to

the alignment features on the base plate.

The HLMP-EG3E-xxxxx LED is recommended for illumina-

tion. If used with the bin table, sufficient illumination can

be guaranteed.

2D Assembly Drawing of ADNS-3080

Shown with ADNS-2120-001 trim lens, ADNS-2220-001

assembly clip and HLMP-EG3E-xxxxx led.

PixArt Imaging provides an IGES file drawing de-

scribing the base plate molding features for lens and PCB

alignment.

The components interlock as they are mounted onto

defined features on the base plate.

The ADNS-3080 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-2120-001 trim lens provides optics for the

imaging of the surface as well as illumination of the
