Effect of Metal behind Tags (Reference)

 Effect of Metal behind Tags (Reference)
The V680-D1KP66T communications distance is reduced if there is any metal material behind the Tag.
If the Tag is to be mounted to metal, then either use a V600-A86 Attachment (sold separately) 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 distance is shown below.
The Attachment is 10 mm thick, and more than one Attachment can be stacked.
