Non-conductive and non-shielding dirt on the road as well as water, fog, snow and
ice have no influence on the accuracy of the position detection.
7.3.3 Minimum Distance Between Identical Transponder Antennas
Figure 9
Minimum distance between identical transponder antennas
Two or more transponder antennas operating at the frequencies 128/64 kHz must
maintain a minimum distance from each other in order not to interfere with each
other. The minimum distance between two HG G-98830YA transponder antennas is
200 mm.
As a matter of principle, larger transponder antennas must maintain a greater dis
-
tance. For safety reasons, smaller transponder antennas must nevertheless maintain
a minimum distance of 200 mm.
If you suspect that magnetic fields are transmitted via the chassis construction:
If in doubt, carry out tests before assembly.
7.3.4 Minimum Distance to Current-Carrying Wires Around the Transponder
Antenna
Figure 10
Minimum distance to current-carrying wires around the transponder antenna
Except for the connection cable of the transponder antenna, current-carrying cables
must be laid at least 150 mm away from the antenna, as these can interfere with the
antenna depending on the power and frequency. It is also important here that there
are no interference effects that exceed 100 units.
The following applies to the reading side of the antenna with the plastic surface:
no closed electrically conductive loops within 300 mm (in or on the floor)
no single metal parts or metal surfaces closer than 50 mm
