Planning the RF300 system
4.3 Installation guidelines
Flush-mounting of transponders and
readers is possible in principle.
However, the size of the transmis-
sion window is significantly reduced.
The following measures can be
used to counteract the reduction of
Enlargement of the non-metallic
spacer below the transponder
The transponder and/or reader are
10 to 20 mm higher than the metal
(The value x ≥ 100 mm is valid, e.g.
for RF310R. It indicates that, for a
distance x ≥ 100 mm, the reader
can no longer be significantly affect-
ed by metal.)
Increase the distances a, b to metal.
The following rule of thumb can be
Increase a, b by a factor of 2 to 3
over the values specified for
Increasing a, b has a greater
effect for readers or transpond-
ers with a large limit distance
than for readers or transponders
with a small limit distance.
