2 ZX-E Series Smart Sensors (Inductive Displacement Type)

*1:Resolution: The resolution is the deviation (±3σ) in the linear output when connected to the ZX-EDA Amplifier Unit. The above values indicate

the deviations observed 30 minutes after the power is turned ON.
(The resolution is measured with OMRON's standard reference object at 1/2 of the measurement range with the ZX-EDA set for the maxi­mum average count of 4,096 per period.)
The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution
may be adversely affected under strong electromagnetic fields.

*2: Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The

linearity and measurement values vary with the object being measured.

*3: Temperature characteristic: The temperature characteristic is measured with OMRON's standard reference object at 1/2 of the measure-

ment range.

*4: The ambient temperature given is only for the sensor head. It is -10 to 60°C for the preamp.

*5: The value given is for an ambient temperature of 25°C.

*6: Do not use in moist environments because the case is not waterproof.

Note 1. Use a separate stabilized power supply for the Amplifier Unit,

particularly when high resolution is required.

2. Wire the Unit correctly. Incorrect wiring may result in damage
to the Unit. (Do not allow wiring, particularly the linear output,
to come into contact with other lines.)

3. Use the blue (0-V) line for the power supply and use the
shield wire (linear output ground) together with the black (lin­ear output) line for linear output. Each of these grounds must
be used for the designed purpose. When not using the linear
output, connect the linear output ground to the 0-V ground.

Precautions

■ Design Precautions

Conform to the specified ratings and performance. Refer to Specifi­cations on page 2 for details.

Objects of certain materials or shapes may not be detectable, or the
detection accuracy may not be sufficiently high.

Environment

Do not operate the product in locations subject to flammable or explo­sive gases.

In order to ensure safe operation and maintenance, do not install the
product in the vicinity of high-voltage devices or power equipment.

■ Wiring

Do not use the product at voltages exceeding the rated values. Doing
so may result in damage.

Do not connect the product to an AC power supply or connect the
power supply in reverse.

Do not short-circuit the load for open-collector output.

■ Correct Use

Design Precautions

Power Supplies

Allow a warm-up period of approximately 30 minutes after turning ON
the power supply.

Mutual Interference

Up to 5 Sensor Heads can be used together by connecting the ZX­CAL2 Calculating Unit between Amplifier Units.

When installing Sensor Heads facing each other or in parallel, sepa­rate them by the minimum distances given in the table below.

Note: The figures in parentheses apply when the mutual interfer-

ence prevention function is used.

Compatibility

Sensors and Amplifier Units are mutually compatible. Sensors can be
added or replaced individually.

Influence of High-frequency
Electromagnetic Fields

Using the product in the vicinity of devices that generate high-fre­quency electromagnetic fields, such as ultrasonic cleaning equip­ment, high-frequency generators, transceivers, mobile phones, and
inverters, may result in malfunction.

Calculating Unit

B

Do not lay the power cable for the product together with or in the same
duct as high-voltage lines or power lines. Doing so may result in in­correct operation or damage due to induction.

Do not connect or disconnect connectors while the power is ON. Do­ing so may result in damage.

■ Adjustment

Setting

When setting threshold values, ensure that the Amplifier Unit’s judge­ment output hold input line is ON so that there is no judgement output
to external devices.

■ Other Precautions

Do not attempt to disassemble, repair, or modify the product.

Dispose of the product using standard procedures for industrial
waste.

These Sensors are not compatible with the ZX-L@@ Smart Sensors
(laser type). Do not connect combinations of ZX-E@@ Smart Sensors
and ZX-T@@ Smart Sensors.

Influence of Metallic Objects

When installing the product, separate it from metallic objects by the
distances shown below.

Wiring

Wiring Check

After wiring is completed, before turning ON the power, confirm that
the power supply is connected correctly, that there are no faulty con­nections, such as load short-circuits, and that the load current is cor­rect. Incorrect wiring may result in failure.

Cable Extension

Do not extend the cable for the Sensor and the Amplifier Unit to a
length exceeding 10 m. Use a ZX-XC@A Extension Cable (sold sep­arately) to extend the Sensor’s cable. Extend the Amplifier Unit’s ca­ble using a shielded cable of the same type.

Power Supply

When using a commercially available switching regulator, ground the
FG (frame ground) terminal.

If the power supply line is subject to surges, connect a surge absorber
that meets the conditions of the operating environment.

When using a Calculating Unit, connect the linear output ground of
the corresponding Amplifier Unit.

ZX-E Series Smart Sensors (Inductive Displacement Type) 9

Connectors

Do not connect or disconnect connectors while the power is ON.

Be sure hold to connectors by the cover when connecting or discon­necting.

Mounting

Handling

When mounting the Sensor Head, do not apply excessive shock by,
for example, using a hammer. Doing so may result in damage or a re­duction in the level of water-proofing. Also, there are screw-shaped
models that require a toothed washer to allow for a tolerance in the
tightening torque for the nut.

When using a heat-resistant model like the ZX-EM02HT, develop de­signs that account for thermal expansion due to rising sensing object
temperature so the sensing object will never touch the sensing sur­face. Also note that any sudden rise in temperature will shorten the
service life of the product.

Tightening Torque

Do not apply excessive torque when tightening the nut. Use a toothed
washer if necessary.

Model Tightening torque

ZX-EM02T 15 N·m

ZX-EM07MT

ZX-EM02HT 59 N·m

Note: The above figure applies for use with a toothed washer.

Mounting Cylindrical Models:
Tighten set screws with a tightening torque of 0.2 N·m max.

Installation Location

Do not install the product in the following locations.

• Locations subject to temperatures outside the specified range

• Locations subject to condensation due to sudden temperature
changes

• Locations subject to humidity levels outside range 35% to 85%

• Locations subject to corrosive or flammable gases

• Locations subject to dust, salts, or metallic powder.

• Locations directly subject to vibrations and shocks

• Locations subject to direct sunlight

• Locations subject to splashes of water, oil, or chemicals

• Locations subject to strong electromagnetic or electrical fields

Maintenance and Inspection

• Be sure to turn OFF the power supply before adjusting or removing
the Sensor Head.

• Cleaning:
Do not use thinners, benzine, acetone, or kerosene for cleaning.
