3-1 Installation of Antenna
3-1-1 Installation Environment
Installation Location
It is assumed that this product is to be used indoors, or outdoors if there is
a roof.
Do not install the Antenna in the following locations.
•
•
Place exposed to direct sunlight.
The ambient temperature is not within a range between 10°C and
55°C or locations with radical temperature changes resulting in
condensation.
•
•
•
•
•
The humidity is not within a range between 35% and 85%.
There is corrosive gas, flammable gas, dust, salt, or metal powder.
The Antenna will be subjected to direct vibration or shock.
Oil, or chemical will be sprayed onto the Antenna.
Vicinity of noise source.
Peripheral environment
1) Influence of peripheral electronic devices
Any peripheral electronic devices present may reduce communication
range. Ambient noise can cause the communications range of the Antenna
to drop.
Ambient noise can be reduced by taking the following countermeasures.
•
•
•
Power Lines and High-tension Lines.
Do not wire the Antenna cable along with high–tension lines or power
lines. Keep the Antenna cable as far away as possible from them.
Inverters, Motors, and Other Driving Mechanisms.
Be sure to ground the frames of driving mechanisms and keep them as
far away as possible from the Antenna.
Switching Power Supplies.
Be sure to ground switching power supplies and keep them as far
away as possible from the Antenna.
2) Influence of peripheral metals
Large metal objects around the Antenna may reduce communication
distance; therefore, place such metal objects at least the following
distances away from the Antenna:
•
Distance between back metal of Antenna and back surface of Antenna:
50cm or more.
•
Distance between side metal of Antenna and side of Antenna: 30cm or
more.
!
Caution
Before installation, perform sufficient tests following the above points.

3-1-2 Mounting the Antenna
Be sure to attach the provided bracket to the Antenna and mount the
Antenna with four M6 screws with spring washers and flat washers as
shown below.
Spring washer
Flat washer
• Mounting Dimensional Drawing
Mount the Antenna at least 50cm away from the flat metal plate. If the
Antenna is mounted only 20cm away, the communication distance will be
90% of the normal distance. For details, refer to 4-2 in Chapter 4.
If the metal is not a flat plate but a rod, its influence will be smaller.
Please verify the effects before installation.
Influence of peripheral
metals during Antenna
installation
When mounting two or more Antennas in close proximity to each other,
ensure that their communications areas do not overlap. For more details,
refer to 4–1 Communications Areas. As a rough guide, when mounting
Antennas in parallel or facing each other, ensure that the Antennas are
separated by at least the dimensions shown below.

4-1 Communications Areas
The following diagram shows the communication area available when a standard Tag is used at
ambient temperature, 25°C. The communication area varies depending on Antenna installation
conditions, Tag forming conditions, Tag installation conditions and ambient temperature;
therefore, verify the communication area beforehand.
Since the coil in the Antenna is more or less rectangular (316mm×265mm), the horizontal
communication distance slightly different from the vertical one. The Antenna surface and Tag
surface are arranged in parallel.

4-2 Influence of Peripheral Metals of Antenna Installation Site
Consider the influence of peripheral metals when installing the Antenna.
Peripheral metals may greatly lower the communication distance for the Antenna.

• Influence of back metals
The following diagram shows the percentage of reduction in communication distance when a
metal is mounted on the back of the Antenna.
The horizontal axis in the diagram refers to the distance between the back of the Antenna and
the metal plate, and the vertical axis refers to the relative communication distance on the
assumption that the communication distance without mounting metals is 100, that is, the
reduced percentage of the communication distance.

4-3 Influence of Tag Angle
4-3
4-3 Influence of Tag Angle
The maximum communications range between the Antenna and Tag will be available if the face
of the Antenna and the face of the Tag are parallel to each other. The communications range will
be reduced if the Tag is mounted at an angle. Take the angle of the Tag into consideration when
mounting.
For reference, the relationship between the Tag angle and the communications range is
illustrated in the graph below. The horizontal axis represents the angle between the face of the
Antenna and the Tag with 0° representing the state where the faces are parallel. The vertical
axis represents the relative communications range from when the angle is 0° and the
communications range is 100% (i.e., the percentage reduction in communications range).

4-4 Effects of Materials on Tags
Take into consideration the effects of the mounting location when mounting the Tag.
Communications range may be reduced if the Tag is near certain objects. The extent to which the
distance will decrease depends on the actual material and its shape. Check the back of the Tag
for the effects of metal and resin objects.
V720–HS04 to V720–D52P30/V720–D52P40
• Effect of Metal Objects
The graph below shows the percentage reduction in communications range when a metal object
is mounted behind the Tag. The horizontal axis represents the distance between the metallic
plate and the Tag. The vertical axis represents the percentage decrease in communications
range, where communications range with no metal object interference is taken to be 100%.
Range between metallic plate and back of Tag (mm)
• Effect of Resin Objects
