4.2 Field data for transponders, readers and antennas
The following table shows the field data for all SIMATIC RF300 components of transponders
and readers. It facilitates the correct selection of a transponder and reader.
All the technical specifications listed are typical data and are applicable for an ambient
temperature of between 0 C and +50 °C, a supply voltage of between 22 V and 27 V DC and
a metal-free environment. Tolerances of ±20 % are admissible due to production or
temperature conditions.
If the entire voltage range at the reader of 20 V DC to 30 V DC and/or the entire temperature
range of transponders and readers is used, the field data are subject to further tolerances.
Note
Transmission gaps
If the minimum operating distance (S
a
) is not observed, a transmission gap can occur in the
center of the field. Communication with the transponder is not possible in the transmission
gap.

Combination with the RF310R
is basically possible, but is
not recommended because
the antenna geometries for
the reader and transponder
are not ideally matched.
