Overview of Optical Mouse Sensor Assembly

2D Assembly Drawing of ADNS‑2051

Figures 3 and 4, shown with

HDNS‑2100, HDNS-2200, and

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 HDNS-2100 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 (see

Figure 4).

The HDNS-2200 clip holds the LED in

relation to the lens. The LED must be

+x

inserted into the clip and the LED’s

leads formed prior to loading on the

PCB. The clip interlocks the sensor

+y

to the lens, and through the lens to

the alignment features on the base

plate.

the bin table, sufficient illumination

can be guaranteed.
