Chapter 1 : Introduction

Problematic :

• The RFID product UHF-CA3-ACX-XMOD doesn’t support any Endcap Scanner options due to a mechanical issue between the RF connector of the RFID and the scanner. That is why both options are not available in the configurator.

Presentation of the product :

• Name : UHF-CA3-ACX-XMOD

• Description :RFID MODULE UHF 500mW Circular polarized Antenna with Xmod connection

• PN concerned : 1100635 (CE) and 1100645 (America)

• Feature : No GPRS and Scanner compliant

Objective :

• Make a specific kitting in order to be compliant with the End-cap scanner options


Chapter 2 : Mechanical Issue

Physical contact between the RF antenna connector and scanner connector.

No possibility to connect the scanner flex

Risk of damage during the drops tests.

Risk to decrease the RFID performance : Noise coupled to the RFID cable

End cap Scanner option not available with this kind of RFID configuration !!!

RFID ModuleRF antenna connector

Scanner connector


Chapter 3 : Mechanical Solution

Avoid the mechanical interferences between the connectors

Move the CAEN RFID module a bit higher by placing a shielding plate underneath

Shielding used in the GPRS option : PN 1050659-001 (METALWORK GSM MC75i)

Solution step by step

i. Un-stick the CAEN module from the PCB board

ii. Put an adhesive tape on top of the shielding plate

iii. Position the shielding between the PCB board and the shielding plate

iv. Stick and Place the RFID module above the shielding plate

v. Put new EMI gaskets on the RFID module (thicker ones)


Chapter 3 : Mechanical Solution

Follow the same routing cable for the scanner flex

No longer mechanical interferences

This solution is valid only for the 1D Laser and Imager scanners

Endcap scanner compliant with this solution : 1D EV15 Imager / 1D Laser SE955


Chapter 4 : Specific Case 2D HHP Scanner

Scanner connector and Flex cable are different from Laser / Imager scanner

If you try to connect UHF Circular Xmod + 2D HHP Endcap, you could succeed in assembling both parts HOWEVER this would lead to some noises issues. Noises coming from the flex would degrade overall RFID performances.

Don’t assembly this way !!!

Problematic :


Chapter 4 : Specific Case 2D HHP Scanner

Follow the same mounting instruction as we previously recommended for Laser and Imager 1D scanner.

Solution :

Solution step by step

i. Use a flex scanner “short version” -> connect the two parts

ii. Put a “Kapton” adhesive tape between both connectors and the PCB

iii. Position the shielding between the PCB board and the shielding plate

iv. Stick and Place the RFID module above the shielding plate


Conclusion :

Thanks for your Attention
