All information refer to the position of the ferrite rod in the antenna:
Figure 12
Nominal reading distances / position of the antenna ferrite rods / metal-free space
In order to obtain a maximum range (> 50 mm) of the reading distance, it is recom
-
mended to install a 10 mm plastic plate or 10 mm distance bolts between steel or
aluminium attachments and the reading antenna. If distance bolts are used, a body
washer must be installed under the reading antenna.
Under certain circumstances, the metal-free space can be reduced by decreasing
the reading distance. For this each application must be checked individually when a
transponder entering the reading area triggers the data and CD signal. The distance
between triggering of the data and CD signal must still be more than 2 cm.
For some antenna variants, individual antennas can be temporarily deactivated via
the data interface. You can see which variants support the deactivation in Table 2 on
page 9.
4.3.2 Connection Cable
Connection cables are not included in the scope of supply. For some antenna vari
-
ants, cables or Bus terminating resistors are available as accessories from the Göt

ting KG. These can be found in Table 3 on page 10. Due to the consistent use of stan
-
dard M12 connectors, suitable cables and adapters are available in specialized trade.
See chapter 3 on page 16 to find out which connectors your antenna variant uses.
If there is a high interference level, shielded cables should be used.
