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.

Field data of RF300 transponders

Observe the following information for field data of RF300 transponders:
● A maximum median deviation of ±2 mm is possible in static mode (without affecting the
● The field data are reduced by approx. 15% if the transponder enters the transmission
