CAUTION: It is advised that normal static precautions be taken in handling and assembly

of this component to prevent damage and/or degradation which may be induced by ESD

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-3040 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-3120-001 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 ADNS-2220 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-PS000 LED is

recommended for illumination.
