
Influence of Metal at Back Surface
The communications range will decrease if there is metal at the back of the V680-D1KP66T-SP 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.
