OSCILLATOR
The components interlock as they are mounted onto
defined features on the base plate.
The ADNS-5700-XXXX sensor is designed for mounting on
a through hole PCB, looking down. The aperture stop and
features on the package align it to the lens (See figure 3).
The ADNS-5100 round lens, ADNS-5100-001 trim lens or
ADNS-5100-002 truncated round lens provides optics for
the imaging of the surface as well as illumination of the
surface at the optimum angle. Lens features align it to the
sensor, base plate, and clip with the LED.

PCB Assembly Considerations
1. Insert the sensor and all other electrical components
2. Bend the LED leads 90 degrees and then insert the LED
3. Insert the LED/clip assembly into PCB.
4. Wave Solder the entire assembly in a no-wash solder
5. Place the lens onto the base plate.

process utilizing solder fixture. The solder fixture is
needed to protect the sensor during the solder process.
It also sets the correct sensor to PCB distance, as the
lead shoulders do not normally rest on the PCB surface.
The fixture should be designed to expose the sensor
leads to solder while shielding the optical aperture
from direct solder contact. A solder fixture MUST be
used to set the correct sensor to PCB distance.

The ADNS-5200 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.
