1 General Description 1.1 Module description The module operates in the UHF frequency range and is optimized for use in industrial applications involving medium distances. The device reads and writes passive tags in line with EPC Generation 2 (ISO/IEC 1800063). The module can be used in the United States and Canada. The module is compliant with the relevant transmission regulations. Wide range of options supported for filtering data. The user can monitor the status of the module using the integrated LEDs.
Figure 1 Example of module housing (with host to user connector mounted) The aluminum housing part (coated with black color) is used to carry the PCBs and also provides shielding for the RF circuit. The plastic top cover part (here green variant) protects the antenna to the environmental harms. The top cover can be supplied in multiple color variants without affecting the module approval.

1.7 PCBs of module in housing Figure 4 mounting of PCBs in housing (interface-PCB shown as example for host) 1.8 Interfacing of module The interfacing of module is made in host product, which provides the typical 24V supply to the module. Also the digital interface of RFID reader is interfaced via serial interface at CMOS Levels. The housing of module is designed to be able to contain the host product as well and a variable amount of external connectors. CONFIDENTIAL acc.
2 Mechanical characteristics 2.1 Housing The housing of module can also be the housing of end product, as there is space for implementing the interface PCB on the bottom side of the RFID reader module. The housing can therefore be modified in part of external connection, as long as the shielding cavity between ANT-PCB and RF-PCB is not touched. The housing material provides a flammability class of UL94-V0. 2.
2.4 Labeling The labeling of the module is applied on the RF-PCB. The top cover of module may be used for host product labeling. 2.5 Shielding Figure 7 shielding volume 2.6 Cooling of RF electronic The RF-PCB is mounted on the metal part of housing to provide a good thermal flux to the environment. Therefore the metal part is used as heat sink and may get hot.
