4.2 Field data for transponders, readers and antennas
If the entire voltage range at the reader of 20 VDC to 30 VDC and/or the entire temperature range
of transponders and readers is used, the field data is subject to further tolerances.
Note
Transmission gaps
If the minimum operating distance (S
center of the field. Communication with the transponder is not possible in the transmission gap,
see section "Impact of secondary fields (Page 44)".
Note
Possible reader-transponder combinations
The tables of the following section show the possible reader-transponder combinations.
Note
Deviations for antennas with plug-in antenna cable
When using antennas with a plug-in 60 cm antenna cable, note that deviations of 10 - 20% can
occur for the field data.
4.2.1 Field data of RF300 transponders
The limit distances (S
window for each reader-transponder combination are listed in the tables below.
In dynamic mode, make sure that rectangular transponders cross the antenna field in the
longitudinal direction.
