Impact of metal on the transmission window
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, make sure that no metal rail (or similar
part) intersects the transmission field.
The metal rail would affect the field data.
● With readers with a large antenna surface (e.g. RF260R) for reasons of communication
reliability, when the transponders are flush mounted in metal, a metal-free space around
the transponders is recommended. This metal-free space should match the size of the
antenna surface.
The impact of metal on the field data (S
g
, S
a
, L) is shown in a table in this section. The
values in the tables describe field data reduction and show the reduced range as a
percentage. The range relates to use in a non-metallic environment. A value of 100% means
no influence on the range.
