Grounding connection

The RF620R/RF630R can be electrically connected to the ground potential through a contact
washer. The tightening torque must be increased in this case to ensure that electrical contact
is made (2.7 Nm).

Planning application

5.2.2.1

Minimum mounting clearances of two antennas of different readers

At 500 mW ERP radiated power, due to the opening angle of the antennas, their fields can
overlap considerably. It is no longer possible to clarify in which antenna field access to the
data of a tag is performed.
In order to avoid this, always keep a minimum distance of 3 m between two antennas of
different RF630R readers with the maximum radiated power of 500 mW ERP.
Dense Reader Mode (DRM)
The readers can also interfere with each other (secondary fields), if the channels (Reader TX,
Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader
channel, we recommend that the Dense Reader Mode (DRM) is used.
5.2.2.2

Antenna/read point configurations

You can connect up to two external antennas to the RF630R reader. The standard setting is
that two antennas are connected when the reader is started.
You have 3 possibilities for aligning the antennas and covering the read point.
