Calculating Tag Speed
When communicating with a moving Tag, specify an AUTO command or POLLING command.
The maximum speed for communicating with the Tag can be calculated simply using the following formula.
D (Distance travelled in communications area) is calculated from the actual measurement or the communications area between the Antenna and Tag.

Calculation Example
In this example diagram, the V680-D1KP66T, V680-HA63A, and V680-HS63 are combined and 256
bytes are read.
This diagram shows the following:
Distance travelled in communications area (D) = 50 mm when Y (communications distance) = 20 mm
Communications time, T = 1.3N +31 = 1.3 × 256 + 31 = 363.8 (ms)
Accordingly, the movement speed in this case will be as follows:
Note 1. The distance travelled in the communications area depends on the read/write distance and the
axis offset. Refer to the diagrams in Communications Area.

In addition to surface mounting, it is also possible to embed the V680-HS63 in a metal casing to protect
it from being struck by other objects. To prevent malfunctioning, allow a space of at least 30 mm
between the Antenna and the sides of the metal casing. If the space is less than 30 mm, the read/write
distance will be greatly diminished. In addition, the height of metal casing must not exceed that of the
Antenna.

Effect of Metal behind Tags (Reference)
Mounting ID Tags to metal workpieces or palettes will affect the communications capabilities. Place non-metallic parts (e.g., plastic or resin) between the metallic parts by referring to the following relationship between the
distance between the ID Tag and the metallic body versus the communications distance.

Influence of Tag Angle (Reference)
Install Antennas and Tags as close to parallel to each other as possible. Communications are possible
even when an Antenna and a Tag are mounted at an angle, but the communications distance will be
shortened. The relation between the angle and the communications distance is shown below.

The Tags have a limited life span. Therefore, install them in locations in which they can be easily
replaced. Use the following procedure to mount the V680-A80 Attachment when required.
1. Mount the Attachment to the workpiece.
Use a tightening torque of 21 to 42 N·m.

Influence of Metal Behind Tag (Reference)
Take the influence of metal behind Tags into consideration when mounting them.
The communications distance is adversely affected if there is any metal material around the Tag. The
degree of influence depends on the type, size, and shape of the material around the Tag. The following
graphs show the influence of metal objects behind the Tag for reference.
• Influence of Metal
The following diagram shows the rate of reduction in the communications distance when metal is
located behind the Tag. The horizontal axis in the diagram indicates the distance between the Tag and
the metal plate, and the vertical axis indicates the relative communications distance at 100% without a
metal plate, i.e, the rate of reduction in communications distance.

Influence of Tag Angle (Reference)
The maximum communications distance can be obtained when the Antenna and Tag are installed in
parallel. When the Tag is installed on an angle, the communications distance is reduced. Consider the
effect of the Tag angle when installing the Tag. As reference data, the following diagram shows the rate
of reduction in communications distance according to the Tag angle. The horizontal axis indicates the
angle when the Tag surface and Antenna surface are in parallel at 0°. The vertical axis indicates the
relative communications distance when the angle is 0° at 100%, i.e., the rate in reduction of the communications distance.

was soaked in or exposed to commonly used organic and inorganic chemicals. In these tests, a
compression-molded test piece (1.3 mm thick) was soaked in the chemical at a specified temperature
for a week (168 houre) and taken out of the chemical, then the weight change, tensile strength, and
elongation of the test piece were immediately measured. If the change in the tensile strength is 15 % or
less, the cange in the elongation is 10 % or less, and the increase in the weight is less than 0.5 %, the
results of the test can be considered normal.
If PFA is exposed to trichloroacetic acid, tri-n-butyl phosphate, perchloroethylene, carbon thtrachloride,
and other liquids (which easily make resin surfaces wet) at a high temperature, it tends to increase its
weight due to absorption and reduce its tensile strength. Even when PFA absorbs chemicals and solvents, its molecular structure will not change, If, however, PFA is subject to temperature or pressure
changes or mechanical damage when it has absorbed chemicals, the chemicals will repeatedly
expand and contract inside pfa, causing mechanical problems such as cracks and bulging. In fact, this
problem occurs with any kind of plastic.
