Influence Of Tag Installation Angle (Reference) - Omron V690 Series User Manual

7-7 Influence of Tag Installation Angle (Reference)

• The maximum communication range can be achieved when the antenna face and tag face are in parallel with each other. If the
antenna and/or tag are inclined, the communication range becomes small. Install the tag paying attention to the tag angle.
• For the tag rotating angle 0 degrees and 90 degrees, deterioration characteristic of communication range depending on the tag angle
is shown below.
• Because of antenna position in the tag, communication range deterioration varies depending on the installation angle (whether "+" or
"-").
• • • • Horizontal installation angle of tag
