Specifications
■Sensor Heads (Reflective)
Note: 1. Beam size: The beam size is defined by 1/e2 (13.5%) of the strength of the beam at the beam center (measured value). Incorrect
detection may occur if there is light leakage outside the defined spot and the material around the target is more reflective than
the target.
2. Resolution: The resolution is the deviation (±3σ) in the linear output when connected to the ZX-LDA Amplifier Unit.
(The resolution is measured with the standard reference object (white ceramic), at the measurement point with the ZX-LDA set
for an 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.
3. 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.
4. Temperature characteristic: The temperature characteristic is measured at the measurement point with the Sensor and reference
object (OMRON’s standard reference object) secured with an aluminum jig.
5. Highly reflective objects can result in incorrect detection by causing out-of-range measurements.

Operation
■Linear Output
The default linear output settings are listed in the following table. These settings are set at the factory and also after initializing
the settings.
Note: Use the monitor focus function when setting the output voltage to ±5 VDC, 0 to 5 VDC or 1 to 5 VDC instead of ±4 VDC.
■Outputs
Discrimination Outputs
There are three discrimination outputs: HIGH, PASS, and LOW.
The following table and illustration show the timing of each output.
Threshold Values
The threshold values form the boundaries between the HIGH,
PASS, and LOW outputs for the measured value.
There are two threshold values: The HIGH threshold and the
LOW threshold. The threshold values contain hysteresis.
Hysteresis
The hysteresis (hysteresis width) is the difference between the
operating and releasing values. If the hysteresis is too small, chat-
tering may occur. If it is too large, releasing may be difficult.

■Inputs
Power Supply (12 to 24 VDC)
A 12 to 24-VDC power supply is connected to the power supply
terminal. When using an Amplifier Unit with a PNP output, the
power supply terminal is also the common I/O terminal for all I/O
except for the linear output.
GND (0 V)
The GND terminal is the 0-V power supply terminal. When using
an Amplifier Unit with an NPN output, the GND terminal is also
the common I/O terminal for all I/O except for the linear output.
Laser OFF Input
When the Laser OFF input is turned ON, the laser emission will
turn OFF, will be displayed on the sub-display, and
an optical level error will occur. The linear output, main display,
judgement outputs, and judgement output indicators will be output
according to the setting for non-measurement.
Zero Reset Input
The zero reset input is used to reset zero or to release the zero
reset. The settings are as follows, according to the length of time
the input is ON:
Note: The above operations are performed when the input is
turned OFF.
Timing Input
The timing input is used to control the timing of the hold functions.
Sampling is performed while this input is ON. It is used, for
example, to hold a specified measured value from during the time
that the timing input is ON.
Reset Input
The reset input is used to reset the outputs. When the reset input
is turned ON, internal operation is interrupted and the specified
values are output from the judgement and linear outputs.

■Hold Functions
The hold functions extract, output, and display data for specific
points, such as the maximum value, the minimum value, etc.
There are six hold functions: Peak hold, bottom hold, sample
hold, peak-to-peak hold, self-peak hold, and self-bottom hold.
Normal Mode (Hold Not Enabled)
In Normal Mode, the measured value is always displayed and out-
put. The timing input is disabled and no hold function will operate.
Peak Hold
In Peak Hold Mode, measurements are performed while the tim-
ing input is ON, and the maximum value during the sampling
period will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is held at the maximum output (current: approximately
23 mA, voltage: approximately 5.5 V) until the first sampling
period is finished. The first measured result (A in the figure below)
is output from the end of the first sampling period to the end of the
second sampling period. After the second sampling period, the
second measured result (B in the figure below) is output and the
sequence is repeated.
Bottom Hold
In Bottom Hold Mode, measurements are performed while the
timing input is ON, and the minimum value during the sampling
period will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is held at the maximum output (current: approximately
23 mA, voltage: approximately 5.5 V) until the first sampling
period is finished. The first measured result (A in the figure below)
is output from the end of the first sampling period to the end of the
second sampling period. After the second sampling period, the
second measured result (B in the figure below) is output and the
sequence is repeated.
Sample hold
In Sample Hold Mode, the measured result when the timing input
is turned ON will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is held at the maximum output (current: approximately
23 mA, voltage: approximately 5.5 V) until the first time the timing
input turns ON. The first measured result (A in the figure below) is
output from the beginning of the first sampling period to the sec-
ond sampling period. After the beginning of the second sampling
period, the second measured result (B in the figure below) is out-
put and the sequence is repeated.

Peak-to-peak hold
In Peak-to-peak Hold Mode, measurements are performed while
the timing input is ON, and the difference between the maximum
value and the minimum value in the sampling period will be the
output value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is held at the maximum output (current: approximately
23 mA, voltage: approximately 5.5 V) until the first sampling
period is finished. The first measured result (P1 − B1 in the figure
below) is output from the end of the first sampling period to the
end of the second sampling period. After the second sampling
period, the second measured result (P2 − B2 in the figure below)
is output and the sequence is repeated.
Self-peak hold
In Self-peak Hold Mode, measurements are performed while the
measured value is larger than or equal to the self-trigger level,
and the maximum value in the period will be the output value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is head at the maximum output (current: approxi-
mately 23 mA, voltage: approximately 5.5 V) until the first sam-
pling period is finished. The first measured result (A in the figure
below) is output from the end of the first sampling period to the
end of the second sampling period. After the second sampling
period, the second measured result (B in the figure below) is out-
put and the sequence is repeated.
Self-bottom hold
In Self-bottom Hold Mode, measurements are performed while
the measured value is smaller than or equal to the self-trigger
level, and the minimum value in the period will be the output
value.
Hold Mode starts when the power is turned ON, immediately after
changing to RUN or T Mode, or immediately after the reset input
is turned OFF.
The output is held at the maximum output (current: approximately
23 mA, voltage: approximately 5.5 V) until the first sampling
period is finished. The first measured result (A in the figure below)
is output from the end of the first sampling period to the end of the
second sampling period. After the second sampling period, the
second measured result (B in the figure below) is output and the
sequence is repeated.
Note: Sampling is not affected by the timing input in Self-bottom

■Timing Functions
Setting Time delay
The time set for the timer is the delay time for the ON-delay timer,
the delay time for the OFF-delay timer, or the pulse width for the
one-shot timer. Set the time according to the requirements of the
control system (e.g., PLC). The timer time can be set to between
0 and 5,999 ms.
Timer Disable
If the timer is disabled, judgement outputs will be made immedi-
ately and the output response time will be determined by the
number of samples to average.
OFF-delay Timer
When the measured value changes from HIGH to PASS or from
LOW to PASS, turning OFF the PASS output is delayed for the
timer time.
ON-delay Timer
When the measured value changes from HIGH to PASS or from
LOW to PASS, turning ON the PASS output is delayed for the
timer time.
One-shot Timer
When the measured value changes from HIGH to PASS or from
LOW to PASS, the PASS output is turn ON with a pulse width
equivalent to the timer time.
When PASS output pulses overlap, the latter pulse has priority.
Therefore, overlapping pulses might sometimes become a single
pulse rather than separate pulses.
Note: Neither the HIGH nor the LOW output are output when the
one-shot timer
■Two-sensor operation
Two-sensor operation enables mutual operation using the mea-
sured values from the two Sensor Heads to generate final out-
puts. Two kinds of outputs, A−B or A+B, can then be selected.
Note: The ranges of display values and linear output values are
automatically doubled when two-sensor operation is used.
An example application of Sensor Heads is given in the
following table when the sensing distance is 100 ± 40 mm
.
Note: Correct distance operation cannot be performed if Sensor

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

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.

Note: Use of controls, adjustments, or procedures other than those specified herein may result in hazardous radiation exposure.
Class Description
Class 1 Lasers which are safe under reasonably foreseeable conditions of operation.
Class 2 Lasers emitting visible radiation in the wavelength range from 400 nm to 700 nm. Eye protection is normally afforded
by aversion responses including the blink reflex.
Class 3A Lasers which are safe for viewing with the unaided eye. For laser emitting in the wavelength range from 400 nm to
700 nm, protection is afforded by aversion responses including the blink reflex. For other wavelengths the hazard
to the unaided eye is no greater than for Class 1. Direct intrabeam viewing of Class 3A lasers with optical aides (e.g.,
binoculars, telescopes, microscopes) may be hazardous.
Class 3B Direct intrabeam viewing of these lasers is always hazardous. Viewing diffuse reflections is normally safe (See
Note).
Class 4 Lasers which are also capable of producing hazardous diffuse reflections. They may cause skin injuries and could
also constitute a fire hazard. Their use requires extreme caution.
Class FDA definition ANSI description
Class I/1 Limits applicable to devices that have emissions in the ultraviolet,
visible, and infrared spectra, and limits below which biological haz-
ards have not been established.
A Class 1 laser is considered to be incapable of pro-
ducing damaging radiation levels during operation
and maintenance and is, therefore, exempt from
any control measures or other forms of surveillance.
Class IIa/2a Limits applicable to products whose visible emission does not ex-
ceed Class I limits for emission durations of 1,000 seconds or less
and are not intended for viewing.
Class 2 lasers are divided into two subclasses, 2
and 2a. A Class 2 laser emits in the visible portion
of the spectrum (0.4 to 0.7 µm) and eye protection
is normally afforded by the aversion response in-
cluding the blink reflex.
Class II/2 Limits applicable to products that have emissions in the visible spec-
trum (400 to 710 nm) for emission durations in excess of 0.25 sec-
ond, providing that emissions for other durations and/or
wavelengths do not exceed the Class I limits. Class II products are
considered hazardous for direct long-term ocular exposure.
Class IIIa/3a Limits to products that have emissions in the visible spectrum and
that have beams where the total collectable radiant power does not
exceed 5 milliwatts.
Class 3 lasers are divided into two subclasses, 3a
and 3b. A Class 3 laser may be hazardous under di-
rect and specular reflection viewing conditions, but
the diffuse reflection is usually not a hazard.
Class IIIb/3b Limits applicable to devices that emit in the ultraviolet, visible, and
infrared spectra. Class IIIb products include laser systems ranging
from 5 to 500 milliwatts in the visible spectrum. Class IIIb emission
levels are ocular hazards for direct exposure throughout the range
of the Class, and skin hazards at the higher levels of the Class.
Class IV/4 Exceeding the limits of Class IIIb and are a hazard for scattered re-
flection as well as for direct exposure.
A Class 4 laser is a hazard to the eye or skin from
the direct beam and sometimes from a diffuse re-
flection and also can be a fire hazard. Class 4 lasers
may also produce laser-generated air contaminants
and hazardous plasma radiation.
