 V680-D1KP66T
 Effect of Metal on Back of RF Tags (Reference)
The V680-D1KP66T communications range is reduced if there is any metal on the back of the RF Tag.
If the RF Tag is to be mounted to metallic material, 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 RF Tag to the metal surface and the communications range is shown below.
The Attachment is 10 mm thick, and more than one Attachment can be stacked.
