 Influence of Metal at Back Surface
The communications range will decrease if there is metal at the back of the V680-D1KP66T RF Tag. If the RF Tag is mounted on metallic
material, use the V600-A86 Attachment (sold separately) or insert a non-metallic spacer (e.g., plastic or resin). The following graphs
show the relationship between the distance from the RF Tag to the metallic surface and the communications range.
You can also use more than one Attachment (10 mm).
