Effect of Metal behind Tags (Reference)
The V680-D1KP66T communications distance is reduced if there is any met al material behind the Tag.
If the Tag is to be mounted to metal, then either use a V600-A86 Attachment (sold sep ar ately) or insert
a non-metal spacer (such as plastic or resin). The relationship between the distance from the Tag to
the metal surface and the communications dista nce is shown below.
The Attachment is 10 mm thick, and more than one Attachment can be stacked.

The transmission distance will be reduced if there is metal in back of
a Tag. When mounting on a metal surface, use the special
Attachment (V680-A81) of another sales or insert a non-metallic
spacer (e.g., plastic, wood, etc.).
The following diagrams show the relationship between the distance
between a Tag and metal surface and the transmission distance. The
