2D Assembly Drawing of ADNS-2051

Figures 3 and 4, shown with

HDNS-2100, HDNS-2200, and

HLMP-ED80-XXXXX.

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-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 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-XXXXX LED is

recommended for illumination. If

used with the bin table, sufficient

illumination can be guaranteed.
