PRECAUTIONS FOR SAFE USE
Please observe the following precautions for safe use of the products.
(1)Installation Environment
･Do not use the product in environments where it can be exposed to inflammable/explosive gas.
･To secure the safety of operation and maintenance, do not install the product close to
high-voltage devices and power devices.
(2)Power Supply and Wiring
･Be sure to use a dedicated amplifier unit (E9NC-TA□□). Connecting to other amplifier unit
may cause damage or fire.
･When shortening cables, be sure to connect wires according to the specifications.
Misconnection may cause damage or fire.
･High-Voltage lines and power lines must be wired separately from this product. Wiring them
together or placing them in the same duct may cause induction, resulting in malfunction or damage.
･Always turn off the power of the unit before connecting or disconnecting cables.
･To prevent cables to cut, fix it in a place where too much tension should not be applied to it.
Avoid pulling cables too strongly or bending them too much.
Repeated flexing: R50 or more
Permanent bend: R20 or more
･Head and output cables must be placed separately from the power line.
(3)Installation
･Use screws or tightening nut for mounting and be sure to tighten screws with a specified torque.
Specified torque: M3 screw:0.6N･m Tightening nut:1.0N･m
(4)Applicable standards
・EN61326-1
・Electromagnetic environment : Industrial electromagnetic environment
(EN/IEC 61326-1 Table 2)
(5)Other Rules
･Do not attempt to disassemble, deform by pressure, incinerate, repair, or modify this product.
･When disposing of the product, treat as industrial waste.
･If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or
smoke, immediately stop using the product, turn off the power, and consult your dealer.
PRECAUTIONS FOR CORRECT USE
Please observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
(1)Do not install the product in locations subjected to the following conditions:
･Surrounding air temperature outside the rating
･Rapid temperature fluctuations (causing condensation)
･Relative humidity outside the range of 35 to 85%
･Presence of corrosive or flammable gases
･Presence of dust, salt, or iron particles
･Direct vibration or shock
･Water, oil, or chemical fumes or spray, or mist atmospheres
･Presence of intense magnetic, electric field or high frequency electric field (use the product in
a place distant from a noise source such as high power relay and high-voltage high-current
switch by 0.5 m or more)
(2)Warming up
・ The circuitry is not stable immediately after turning the power ON, and the values gradually
change until the Sensor Head is completely warmed up.
・ Before using the product, check that its functionality and capability are normal.
(3)Maintenance and inspection
･Always turn off the power of the unit before connecting or disconnecting cables.
･Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the sensor.
･If oil that becomes extremely viscous when it's dry, such as cutting oil, attaches to the rubber
boot, the operation may not work properly.
Wipe off with a waste cloth dampened with absolute alcohol.
･The rubber boot may be significantly degraded by organic solvent or ozone in the air or
ultraviolet rays in the environment. In such cases, replace the rubber boot regularly (6 months to
a year).
･Rubber boots are coated with grease. Please do not remove the grease when the rubber boot is
used, since sliding movement may be degraded if it is removed.
･When it used after wiping off the oil, perform regular maintenance not to rust. Be sure to check
that there is no influence on the measurement due to the oil when it is used with the oil.
■ Do not use this product under water, rain or outdoors.

■ Shortening the connection cable for use
■ Shortening the connection cable for use
Push the operation lever at the operation slot with the slotted
screwdriver and pull out the wire to adjust the cable length.
The tip of the screwdriver must be 2 mm or less. The type of
screwdriver whose tip width becomes broaden toward its root
cannot be used.
■ Procedure to connect the connector
(1) According to "STRIP GAUGE" shown on the side of the
product, strip the coating of the shield for 20 mm or less, strip
the coating of the core wire for 7 to 8 mm, and twist the wire
for several times.
Connecting part
Wire coating
(2) Insert the wire all the way to the wire
insertion slot. Make sure that the wire coating
is located inside the wire insertion slot and
the tip of the conductor passes through the
connection part. Connect wires as follows.
Terminal No.1: Brown, No.2: Shield, No.3:
White, No.4: Red.
Operation lever
(3) Push the slotted screwdriver all the way to the releasing slot
(White)
and pry the slotted screwdriver up and down lightly. When you
feel a click on the slotted screwdriver, pry it to the reverse
direction of the wire insertion direction. The operation lever will
recover with a click sound.
(4) Check that the operation lever recovers and the wire coating
enters into the wire insertion slot. The shield wire cover must
not be shorted circuited. (The wires are connected when you
pull the wire and feel a resistance.)
■Using air supply
(E9NC-TH5L/E9NC-TH5LF/E9NC-TH12L/E9NC-TH12LF)
・ The suction air must be dry air with a negative pressure of 0.04 to 0.067 MPa.
・ The outside diameter of the tube for air suction inlet must be 4 mm.
・ Air suction draws the spindle in.
・ If the spindle extrusion rate is high, the amplifier indication may display an error when
a workpiece is contacted.
・ Too much impact may shift the ball retainer inside the bearing, resulting in less
operating range. If so, adjust the spindle rate.
■Installation
1. Remove the cap.

2. Attach the hose elbow.
Manually tighten the M5 screw until the gasket contacts the wall. Then use the
dedicated wrench to tighten by 90°.

3. Installing Heads
<Straight Model>
（E9NC-TH5S/E9NC-TH5Ｌ/E9NC-TH12S/E9NC-TH12L）
・ Mounting head, be sure to grab the stem.
・ To attach the head to other equipment, avoid securing it on a
position where a screw directly contacts this product.
・ As this product uses a ball bearing, tightening the stem too much
could damage the measurement axis, resulting in crippled
movement.
・ To attach it to equipment using a holder, use the <recommended
mounting jig> with specified tightening torque of 0.6 N ・ m to
secure.
・ Attach the stem so that the slotted block should be tightened by
the screw. Never attach the stem by cutting screw thread in the
Ø8 mm hole and by screwing the stem with a setscrew. Or sliding
movement or precision may be degraded.
<Flanged Model>
(E9NC-TH5SF/E9NC-TH5LF/E9NC-TH12SF/E9NC-TH12LF)
・ Recommended diameter of the hole to attach the head is
Ø9.7±0.15 mm.
・ The mounting plate thicknesses are shown below:
E9NC-TH5SF/E9NC-TH5LF: 9 to 11 mm
E9NC-TH12SF/E9NC-TH12LF: 7 to 11 mm
・ To attach the head, always use the accessory tightening nut,
wave washer, clamp spanner, and pin that come with the product.
The tightening torque shall be applied so that the wave washer
should be completely flat.
Recommended tightening torque: 1.0 N ・ m
Maximum tightening torque: 2.0 N ・ m
ATTENTION
・ To prevent cables to cut, fix it in a proper place. Avoid pulling
cables too strongly or bending them too much.
・ The degree of parallelization affects the precision of detection.
Use the mounting bracket (or sleeve) so that it should be kept
within 0.3 mm for 100 mm of movement.
・ Do not apply force to rotation direction after securing the stem.
Or it may be damaged.
4． Attaching the probe
Unit: mm
・ Use the dedicated wrench that comes with the product for attaching
(82.7)
and detaching the probe. Do not apply torque of 0.1 N ・ m or more to
the spindle during the task. Otherwise damage may result.

・ Unless you use a flat probe, it is recommended to use the accessory
spring washer of nominal 2.5 or screw lock to prevent the probe to
loosen. (Reference tightening torque value: 0.05 to 0.06 N ・ m)
