 Influence of Metal at Back Surface of RF Tags
The communications range will decrease if there is metal at the back of the V680S-D2KF67 RF Tag. If
the RF Tag is mounted on metallic material, use 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.
