Safety Precautions
This instruction manual describes the operation and function of the EX-V. Read this
manual carefully to ensure safe use and maximum performance from your EX-V.
Symbols
The following symbols alert you to important messages. Be sure to read these
messages carefully.
General precautions
WARNING
CAUTION
Note:
• At startup and during operation, be sure to monitor the functions and performance
of the EX-V.
• We recommend that you take substantial safety measures to avoid any damage in
the event a problem occurs.
• Do not open or modify the EX-V or use it in any way other than described in the
specifications.
• When the EX-V is used in combination with other instruments, functions and
performance may be degraded, depending on operating conditions and the
surrounding environment.
• Do not use the EX-V for the purpose of protecting the human body.
Failure to follow instructions may lead to injury. (electric
shock, burn, etc.)
Failure to follow instructions may lead to product damage.
Provides additional information on proper operation.

Warning and cautions specific to the EX-V Series
Operating environment
For optimum performance of the EX-V, always maintain a proper operating environment.
To prevent malfunction, do not install the EX-V in the following places:
• Places directly exposed to sunlight.
• Places where the ambient temperature drops below 0
°
C or exceeds 50°C.
• Places where the relative humidity drops below 35% or exceeds 85%.
• Places where temperature fluctuations may cause condensation.
• Places where the EX-V may be exposed to corrosive or flammable gas.
• Places exposed to airborne dust or corrosive substances such as salt or
metal particles.
• Places where the EX-V may be subjected to vibration or impact.
• Places where water, oil or chemicals may splash the EX-V .
• Places where the EX-V may be affected by noise interference.
Connecting the EX-V to analog input equipment
Take the following countermeasures to prevent the EX-V from malfunctioning due
to noise interference.
Note 1: Use a 1-core shielded cable for the output line. When using an analog
voltage signal, do not use a cable longer than 10 m. If the cable needs to be
longer than 10 m, convert the voltage signal into a current signal.
Note 2: Keep the wiring and connection cables separate.
Note 3: Isolate the wiring and connection cables from high-voltage or power lines;
otherwise noise may cause the EX-V to malfunction.

Mounting
• Tighten the EX-305V set screw and EX-110V nut away from the tip of the
sensor head as shown in the figure.
• Referring to the measuring distance in the table below, determine the distance
between the tip of the sensor head and target.

Flush-mounting
Note: After making the adjustment, do not change the position of the nut or screw.
If the position is changed, the output characteristics may change even when the
nut or screw is positioned in the range shown in the figure.
To flush-mount the sensor head in a metal base, follow the guidelines given in the
table below.
* The table above shows the dimensions to use when the metal base is iron.
* The table above shows the dimensions to satisfy the specifications when the
sensor head is flush-mounted after the output characteristics have been
adjusted with no metal present around the head.

CAUTION
When mounting two or more sensor heads of the same model in parallel
• The sensor may not output the correct voltage due to mutual interference. Make
sure that the distance between sensor heads adjacent to each other is larger
than the values shown in the table below. (This allows the display resolution
specification to be satisfied when the number of measurements to average is
"64".)

• When two sensor heads are mounted in parallel, mutual interference can be
prevented by alternately oscillating the sensor heads using the synchronous
input terminal (
➮
page 4
).
Tightening torque
To tighten the EX-305V set screw, apply a torque of 0.2 N•m or less.
To tighten the nut of the other sensor heads, apply a torque shown in the table

• If the applied tightening torque exceeds the specified one, the sensor
head may be deformed or malfunction.
• If the sensor cable is installed in the same conduit as high voltage lines or
power lines, the sensor may malfunction. Be sure to keep the wiring
separate.
Note: Do not change the sensor cable length (3 m). If the cable is extended or cut,
the characteristics will change.

2.1 Measurement Modes
The EX-V series provides the following four measurement modes: "Bottom-deadcenter mode", "Eccentricity/vibration mode", "Thickness/gap mode" (which are
basic modes for quick operation), and "Manual mode" (which allows users to
perform setting as desired). This section explains the major functions of each
mode.
2.1.1 Bottom-dead-center mode
2
This mode is used to measure the displacement of the origin position of a machine
with stroke movements such as a press. When the displacement of the bottom
dead center or origin position is out of the preset tolerance range, the sensor
outputs an Alarm signal.
Major applications
• Detecting the bottom dead center position of a press
• Detecting the bottom dead center position of a press-fit machine
• Detecting the bottom dead center position of a welding machine
• Pressure control for a injection molding machine
• Measuring the depth of the recess on a piston head
2.1.2 Eccentricity/vibration mode
This mode is used to measure the roller eccentricity or abnormal machine vibration.
When the amplitude of the runout or vibration is larger than the preset tolerance
limit value, the sensor outputs an Alarm signal.

This mode is used to measure target thickness or gap with a direct reading value.
When the thickness or gap is larger or smaller than the preset upper or lower value
for the tolerance limit, the sensor outputs an Alarm signal.
Major applications
• Measuring hoop material thickness
• Checking grindstone abrasion
• Thickness control during polishing ceramic components
