Overview of Optical Mouse Sensor Assembly
2D Assembly Drawing of ADNS-2051
Figures 3 and 4, shown with
HDNS-2100,
HLMP-ED80-XX000.
Avago 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-2051 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 (see Figure 3).
The
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 (see
Figure 4).
The HDNS-2200 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 recom-
mended for illumination. If used with
the bin table, sufficient illumination
can be guaranteed.
