V680-HS65
Effect of Surrounding Metals on the Antenna (Reference)
In addition to surface mounting, it is also possible to embed the V680-HS65 in a metallic material to
protect it from being struck by other objects. To prevent malfunctioning, allow a space of at least
100 mm between the Antenna and the sides of the metallic material. If the space is less than 100 mm,
the read/write distance will be greatly diminished. In addition, the height of metallic material must not
exceed that of the Antenna.
30 mm

Metallic material
Note 1: Do not bend the cable into a curve tighter than 22 mm in radius.
2: The communications distance will be reduced significantly if the Antenna is installed closer
than 100 mm to metal surfaces.
Mutual Interference between Antennas (Reference)
To prevent malfunctioning due to mutual interference when using more than one Antenna, leave
sufficient space between them as shown in the following diagrams.
