 V680-D1KP66T-SP
 Effect of Metal on Back of RF Tags (Reference)
The V680-D1KP66T-SP communications range is reduced if there is any metallic material on the back
of the RF Tag. If the RF Tag is mounted on metallic material, 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.
