Installation
Mutual Interference with RF Tag (Reference)
Provide the mounting distances indicated below to prevent malfunctions due to mutual interference
when using multiple RF Tags.
When V680-H01-V2 is Used
Note: Provide the interval of 250mm or more, when the communications distance of the antenna and RF Tag is
60mm or less.
When V680-HS65 is Used
Influence of RF Tag Angle (Reference)
The maximum communications distance can be obtained when the Antenna and RF Tag are installed
in parallel. When the RF Tag is installed on an angle, the communications distance is reduced. Con-
sider the effect of the RF Tag angle when installing the RF Tag. As reference data, the following dia-
gram shows the rate of reduction in communications distance according to the RF Tag angle. The
horizontal axis indicates the angle when the RF Tag surface and Antenna surface are in parallel at 0
°
.
The vertical axis indicates the relative communications distance when the angle is 0
°
at 100%, i.e., the
rate in reduction of the communications distance.
