Aids for calculating the field data
You will also find a tool for calculating field data on the DVD "RFID Systems, Software &
Documentation". Using this tool, among other things you can calculate the operating
distance (S
a
), limit distance (S
g
) and transmission window (L).

Field data of transponders and readers
The following tables show the field data for all SIMATIC RF200 components of transponders
and readers. This makes the correct selection of a transponder and reader particularly easy.
All the technical specifications listed are typical data and are applicable for an ambient
temperature between 0 °C and +50 °C, a supply voltage between 22 and 27 VDC and a
metal-free environment.
Tolerances of ±20 % are permitted due to production or temperature
conditions.
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
I
f 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.
