1Introduction
The iRFID101 is an ATEX and IECEx approved Zone 1 RFID Reader Enclosure with
intrinsically safe RF outputs; it is designed to allow the deployment of RFID readers
in hazardous areas. The concept allows installation of equipment from leading RFID
Reader vendors such as SICK, CAEN and Impinj, meaning that the user may select
the vendor of their choice when extending RFID reading into hazardous areas.
Each type of RFID Reader or RF transmitting device is rigorously checked and
tested by Extronics to ensure conformity to the latest standards. This means that
the user may select the vendor of their choice when using a reader in hazardous
areas. However equipment not previously approved will require assessment to
determine its suitability.
The intrinsically safe RF outputs of the iRFID101 allows users to choose any
antenna for use with their wireless hardware e.g. Extronics iANT200 range of high
quality rugged outdoor antennas. Any antennas not listed in the Extronics range
must be assessed by the user to ensure they meet the requirements for installation
of non-electrical equipment in hazardous areas. Up to eight antennas can be
utilized. Optional features include surge arrestors for lightning suppression in
outdoor installations.
