Overview of Optical Mouse Sensor Assembly
2D Assembly Drawing of ADNS-3060
Shown with ADNS-2120,
ADNS-2220 and HLMP ED80-
XX000.
Agilent Technologies provides
an IGES file drawing
describing 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-3060 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 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 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-ED80-XX000 LED
is recommended for
illumination. If used with the
bin table, sufficient
illumination can be guaranteed.
