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.
Shown with ADNS-2120-001, ADNS-2220-001 and HLMP-
EG3E-xxxxx.
PixArt Imaging provides an IGES file drawing de-
scribing the base plate molding features for lens and PCB
alignment.
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 components interlock as they are mounted onto
defined features on the base plate.
The ADNS-3090 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 HLMP-EG3E-xxxxx LED is recommended for illumina-
tion. If used with the bin table, sufficient illumination can
be guaranteed.
The ADNS-2120-001 trim lens provides optics for the
imaging of the surface as well as illumination of the
