Effects Of The Materials Of The Mounting Surfaces On The Range - Siemens SIMATIC RF600 System Manual

RF600 system planning
4.4 Minimum distances and maximum ranges
Suboptimal transponder alignment for all antenna types
If the angle is changed within the y-z plane, this causes a reduction in range for all antenna
types.

Note
Exceptions
The suboptimal transponder alignment does not apply to the transponders RF625T and
RF630T. You will find additional information on this in the sections dealing with the
transponders.

Effects of the materials of the mounting surfaces on the range

Effects due to antenna mounting
For the RF640A, RF642A, RF650A, RF660A and RF680A antennas, the antenna gain and
therefore the maximum read/write range does not depend on the selected material of the
mounting surface. In contrast to this, the antenna gain of the RF615A and RF620A antennas
and therefore the maximum read/write range of transponders depends on the mounting
surface of the antenna. To achieve the maximum range with an RF615A/RF620A antenna,
the antenna needs to be mounted on a metallic surface of at least 150 x 150 mm.
You will find more detailed information on antenna gain in the subsections of the section
"Antenna patterns (Page 257)".
