Fundamentals of application planning

4.1.1

Selection criteria for SIMATIC RF300 components

Assess your application according to the following criteria, in order to choose the right
SIMATIC RF300 components:
● Transmission distance (read/write distance)
● Tracking tolerances
● Static or dynamic data transfer
● Data volume to be transferred
● Speed in case of dynamic transfer
● Metal-free rooms for transponders and readers
● Ambient conditions such as relative humidity, temperature, chemical impacts, etc.

Transmission window and read/write distance

The reader generates an inductive alternating field. The field is strongest near to the reader.
The strength of the field decreases in proportion to the distance from the reader. The
distribution of the field depends on the structure and geometry of the antennas in the reader
and transponder.
A prerequisite for the function of the transponder is a minimum field strength at the
transponder achieved at a distance S
