Note
Effect on inductive fields by not maintaining the minimum distances of the readers
If the values fall below those specified in the "minimum distance readers or antennas", there
is a risk of the function being affected by inductive fields. In this case, the data transfer time
would increase unpredictably or a command would be aborted with an error.
Keeping to the values specified in the "Minimum distance readers or antennas" table is
therefore essential.
If the specified minimum distance cannot be complied with due to the physical configuration,
the SET-ANT command can be used to activate and deactivate the HF field of the reader.
The application software must be used to ensure that only one reader is active (antenna is
switched on) at a time.

Overview

The transponder and reader complete with their antennas are inductive devices. Any type of
metal in the vicinity of these devices affects their functionality. Some points need to be
considered during planning and installation if the values described in the "Field data
(Page 39)" section are to retain their validity:
● Minimum spacing between two readers or their antennas
● Minimum distance between two adjacent data memories
● Metal-free area for flush-mounting of readers or their antennas and transponders in metal
● Mounting of multiple readers or their antennas on metal frames or racks
