4.4.3 Effects of metal on different transponders and readers
Mounting different transponders and readers on metal or flush-mounting
Certain conditions have to be observed when mounting the transponders and readers on
metal or flush-mounting. For more information, please refer to the descriptions of the
individual transponders and readers in the relevant section.
4.4.4 Impact on the transmission window by metal
In general, the following points should be considered when mounting RFID components:
Direct mounting on metal is allowed only in the case of specially approved transponders.
Flush-mounting of the components in metal reduces the field data; a test is
recommended in critical applications.
When working inside the transmission window, it should be ensured that no metal rail (or
similar part) intersects the transmission field.
The metal rail would affect the field data.
The impact of metal on the field data (S
g
, S
a
, L, B) is shown in tabular format in this section.
The values in the table describe the reduction of the field data in % with reference to non-
metal (100 % means no impact).
