WOODWARD 9905-003M Communication gateway module

The typical range for RFID card to XE 020/ANT antenna module is 40 mm for the recommended RI-I02112A-03 RFID card (assuming an aluminium front panel). The card is recognised when the RFID LED on the front of the operating panel turns green (for 3 secs) (refer to chapter “RFID status LED“). There is no provision to detect multiple cards at the same time. If several RFID cards are within range, either only one will be detected or this will cause a detection error, in which case the RFID status LED will turn red.

Minimum XE 020/ANT antenna module clearance 

To guarantee the specified antenna range the following minimum clearance between antenna and base material (aluminium) must be respected.Suitable precautions must be taken to prevent any cables located behind the antenna from causing antenna detuning, e.g. providing a cover.
