Precautions
■ Design Precautions
Ratings and Performance
• Conform to the specified ratings and performance. Refer to
Specifications for details.
1. Do not impose voltage exceeding the rated voltage, other-
wise the Sensor may be damaged.
2. When supplying power to the Sensor, make sure that the
polarity of the power is correct, otherwise, the Sensor may
be damaged. Do not connect to an AC power supply.
3. Do not short-circuit the load for the open collector output,
otherwise the Sensor may be damaged.
• Do not disconnect the connector connecting the Sensor Head
and the controller while power is being supplied, otherwise the
Sensor may be damaged.
• Allow a warm-up period of approximately 10 minutes after turn-
ing ON the power supply.
• Objects of certain materials or shapes may not be detectable, or
the detection accuracy may not be sufficiently high. These in-
clude materials that are transparent or have extremely low reflec-
tivity, and objects that are smaller than the Sensor’s spot
diameter or have extreme curvature or inclination.
Power Supply and Wiring
• Prior to turning ON the power supply after wiring is completed,
check to make sure that the power supply is correct, that there
are no mistaken connections, e.g., connections that would short-
circuit the load, and that the load current is appropriate. Incorrect
wiring may result in damage to the Sensor or Unit.
• The total length of the Sensor cable or Amplifier cable must be
10 m or less. Use an ZX-XC@A Extension Cable (order sepa-
rately) if required to extend the cable from the Sensor. Use a
shielded cable to extend the Amplifier cable. The shielded cable
must be the same as that of the Amplifier cable.
• Do not lay a power supply cable for the ZX together with high-
voltage lines or power lines to prevent interference, damage, and
malfunction.
• 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 ab-
sorber that meets the conditions of the usage environment.
• When using a Calculating Unit, connect the corresponding linear
ground of the Amplifier Unit.
Compatibility
• All Sensor Heads and Amplifier Units are compatible. Different
Sensor Heads may be purchased at a later date and used with
existing Amplifier Units.
Mutual Interference
• Two Sensor Heads can be used together, without danger of mu-
tual interference, by connecting the ZX-CAL Calculating Unit be-
tween two Amplifier Units.
Maintenance
• Always turn OFF the power supply before adjusting or removing
the Sensor Head.
• Cleaning
Do not use thinners, benzine, acetone, or kerosene for cleaning.
If dust or oil adheres to the filter on the front of the Sensor Head,
use the following procedure to clean.
1. Use a blower brush (used to clean camera lenses) to blow
large dust particles from the surface. Do not blow the dust
away with your mouth.
2. Use a soft cloth (for lenses) with a small amount of alcohol
to remove the remaining dust. Do not use a scrubbing
action when cleaning because scratches on the filter could
result in Sensor inaccuracy.
■
Other Precautions
Environment
1. Do not use the Sensor in strong electromagnetic fields or in
an environment where the operation of the Sensor is sub-
ject to the reflection of intense light (such as other laser
beams or electric arc-welding machines.)
2. Do not operate the Sensor in the following locations:
• Locations subject to strong vibration.
• Locations subject to direct sunlight or near heating equip-
ment.
• Locations subject to high humidity.
• Locations where the Sensor would accumulate dust, dirt,
metallic powder, etc.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to organic solvents, water,
oil, etc.
• Locations subject to strong electromagnetic or electrical
fields.
• Locations subject to rapid changes in temperature.
• Locations subject to freezing.

Laser Safety
The ZX-LD@@, ZX-LD@@L, ZX-LD@@V, and ZX-LD@@VL Sen-
sor Heads are Class 2 Laser Products according to EN60825-1
(IEC825-1) and Class II Laser Products according to FDA (21
CFR1040.10) (See Note). The ZX-LT@@@ Sensor Heads are
Class 1 and Class I Laser Products, respectively. The ZX Series
is meant to be built into final system equipment. Pay special atten-
tion to the following precautions for the safe use of the product:
Note: Europe: Class 1 and Class 2 of EN60825-1: 1994 =
IEC825-1: 1993
U.S.A.: Class I and Class II of FDA (21 CFR1040.10)
1. Use this product as specified in this instruction manual.
Otherwise, you may be exposed to hazardous laser radia-
tion.
2. The ZX-series Smart Sensors radiate laser beams in the
visible light range. Do not expose your eyes directly to the
laser radiation. Ensure that the laser beam path is termi-
nated during use. If a mirror or shiny surface is positioned in
the laser beam path, ensure that the reflected beam path is
also terminated. If the Unit must be used without terminat-
ing the laser beam path, position the laser beam path so
that it is not at eye level.
3. To avoid exposure to hazardous laser radiation, do not dis-
place nor remove the protective housing during operation,
maintenance, and any other servicing.
4. The user should return the product to OMRON for all repair
and servicing.
5. As for other countries, observe the regulations and stan-
dards specified by each country.
