• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Reflective sensor of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
Component Installation and Handling
„ Power Supply and Wiring
• To extend the output cables of Amplifier Units, shielded cables of the same
specifications as the output cables must be used.
• When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit
the operating environment.
• When using two ore more amplifier units, make sure that the linear GND line of the
amplifier units are connected to each other.
• Before turning ON the power after the product is connected, make sure that the
power supply voltage is correct, there are no incorrect connections (e.g. load shortcircuit) and the load current is appropriate. Incorrect wiring may result in breakdown
of the product.
• The cables must be 10m or shorter in total length, for both sensor head and amplifier
units. To extend the cable from the sensor head, an optional extension cable
(ZX-XC…A) must be used. For extension of the cable of amplifier units, shielded
cables of the same type must be used.
• When using calculation units, make sure that the linear GND lines of the amplifier
units are connected to each other.

Introduction
Introduction Precautions for Correct Use
„ Warming Up
After turning ON the power supply, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measured values may fluctuate gradually.
„ Maintenance and Inspection
• Always turn OFF the power supply before adjusting or connecting/disconnecting the
sensor head.
• Do not use thinner, benzene, acetone or kerosene to clean the sensor head and
amplifier units. If large dust particles adhere to the front filter of the sensor head, use
a blower brush (used to clean camera lenses) to blow them off. Do not blow the dust
away with your mouth. To remove smaller dust particles, use a soft cloth (for lenses)
with a small amount of alcohol. Take care not to wipe them off with excessive force.
Scratches on the filter may cause errors.
„ Sensing Object For Reflective Type Sensor Head
The product cannot accurately measure the following types of objects: Transparent
objects, objects with an extremely low reflective sensor ratio, objects smaller than the
spot diameter, objects with a large curvature, excessively inclined objects, etc.
„ Mutual Interference
Inserting a calculation unit between amplifier units can prevent mutual interference
between two sensor heads. However, this may not work efficiently if one sensor head is
saturated and a laser beam of the other sensor head is input. If you are interested in
installing a calculation unit in order to prevent mutual interference, carry out a test using
the actual system beforehand.

„ Adjusting the Optical Axis
Affix the optical axis adjustment seal (supplied with the sensor) on the front side of the
receiver, and adjust the receiver position so that the laser beam is irradiated at the
center of the cross on the seal.
For more accurate adjustment, adjust the receiver position so that the Amplifier Unit
shows the largest reading.
Section 2 Installing Sensor Heads
Optical axis adjustment seal
• When adjusting the receiver position, take care not to touch the emitter and receiver of the sensor
head. Adhesion of finger marks may hinder correct measurements. If you have touched them,
wipe them with a clean, soft cloth.
• The standard received light amount and scaling must be set after completion of optical axis
adjustment.
• After optical axis adjustment is complete, remove the optical axis adjustment seal.

Wiring Input/Output Cables
The input/output cable has the following wires.
Wire the cable correctly. Incorrect wiring may damage the Smart Sensor.
(1) A 12- to 24-VDC (±10%) 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.
Use a stabilized power supply separate from other devices and power systems for the
Amplifier Unit, particularly when high resolution is required.

(2) 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.
(3) The HIGH judgement output outputs judgement results (HIGH).
(4) The PASS judgement output outputs judgement results (PASS).
(5) The LOW judgement output outputs judgement results (LOW).
(6) The linear output outputs a current or voltage in accordance with the measured
value.
(7) The linear output GND terminal is the 0-V terminal for the linear output.
• This ground wire must be grounded separately from the other ground wires.
• Always ground the linear output terminal even when linear output is not used.
(8) If this LD-OFF signal is ON, the laser will stop emission, causing a light amount
error. In this case, the linear output, digital display, judgement output and
judgement output display signals will be output according to the non-measurement
settings.
The sub-display will show [LDOFF].
(9) The zero reset input is used to execute and clear zero reset.
p.118
(10) The timing input is for signal input from external devices. Use it for hold function
timing. The sub-display will show [TIMIG] while the hold function timing is input.
(11) The reset input resets all measurement processing and outputs. The sub-display
will show [RESET] while the hold function reset is input. The linear and judgement
output signals will be output according to the non-measurement settings. If this
reset input switches ON while the hold function is used, the state in effect before
the hold function was set will be restored.

Setting the Measurement Sensitivity (Gain Switching)
This section describes how to set the measurement gain according to the surface condition of
the sensing object.
Setting the measurement gain to AUTO will automatically adjust the sensitivity to the optimum
level for the object.
If the amount of reflective sensor light on the object does not change excessively, stable
measurements can be carried out by fixing the measurement gain to an appropriate one.
Five measurement gains are available: [AUTO] for automatic adjustment, and [BLACK],
[WHITE], [METAL] and [MIROR], which are fixed measurement gains. In the case of fixed
measurement gains, the measurement sensitivity increases in the order [MIROR], [METAL],
[WHITE], [BLACK], [MIROR] with the lowest measurement sensitivity and [BLACK] with the
highest measurement sensitivity.

Comparing Measured Values (Differentiation
Function)
Use the differentiation function to detect only sudden changes in the measured values that
occur during very short periods of time.
The differentiation function detects changes between the present value and the measured
value that is in effect just before the comparing pitch. The coefficient of this comparing pitch is
defined as the differentiation cycle.
The relationship between the differentiation cycle and comparing pitch can be calculated by
the following equation.
Comparing pitch = Differentiation cycle x 150µs

The following table outlines the three methods for setting the threshold values.
Method
Details
Direct input
The threshold values can be set by directly inputting the numeric values.
Direct input is useful when you know the dimensions for an OK judgement or when
you want to fine-tune threshold values after teaching.
Position teaching
Performs measurement and uses the measurement results to set threshold values.
Position teaching is useful when threshold samples, i.e., with the upper and lower
limits, can be obtained beforehand.
Two-point teaching
Sets the intermediate point between the first and second teaching points as the
threshold value.
Two-point teaching is useful to detect small surface steps on the sensing object.
Automatic teaching
Performs measurement continuously while the keys are held down and sets the
maximum and minimum measurements during that period as the threshold values.
Automatic teaching is useful when you want to set threshold values by starting the
device and obtaining real measurements.
Hysteresis (hysteresis width) can also be set for threshold values. Set hysteresis when judgements are
unstable to prevent chattering.

• When turning the power ON, if you want to keep the zero reset level data that was in effect when
the power was turned OFF last time, make sure that zero reset memory is enabled.
If zero reset memory is enabled, the zero reset level data will be written in the Amplifier Unit nonvolatile memory (EEPROM) at each zero reset. The EEPROM can be written a maximum of
100,000 times. Writing the zero reset level for each measurement can, therefore, use up the life of
the memory and lead to malfunctions.
• Unlike the old models ZX-LDA11 and LDA41, zero reset memory is disabled by default to protect
the EEPROM in the case of ZX-LDA11-N and LDA41-N. Thus, care must be taken when using
zero reset memory with the old models ZX-LDA11/LDA41.
• Even if zero reset memory is disabled, the zero reset level will be saved if threshold values or
other functions have been changed. Zero reset will continue after startup when these functions
have been changed.

Q&A
Question
Answer
Can calculations be performed with ZX-E
and ZX-T series Smart Sensors?
Contact your OMRON representative.
Can the ZX-SF11 Interface Unit used with
the ZX-LDA11/LDA41 or ZX-E-series
Smart Sensors be used with the ZXLDA11-N/LDA41-N Smart Sensors?
Yes, if the Interface Unit is version 2.0 or later.If the Interface Unit is an
earlier version, contact your OMRON representative.
(The Interface Unit version can be checked with the Smart Monitor.)j
Why does an error occur and settings
cannot be made when teaching or directly
inputting threshold values?
Threshold values cannot be set using teaching or by direct input if the
following condition is not met:
HIGH threshold value - LOW threshold value - hysteresis width
p.88
When scaling is executed, an error
appears on the sub-display and settings
cannot be made.
Scaling cannot be set for one of the following reasons:
• Scaling has been attempted when the measured value is outside the
measurement distance range.
• When two-point scaling has been executed, the distance between
the measured values for the two points is not 1% or more of the rated
measurement range.
p.72
When monitor focus is executed, why
does an error appear on the sub-display
and the settings cannot be made?
Monitor focus settings cannot be made when the distance between the
two specified points is not 1% or more of the rated measurement range.
p.95
Can calculations be performed with 3 or
more Amplifier Units?
In the case of ZX-LDA11-N/LDA41-N Amplifier Units, calculations can
be performed with up to eight units (CH1 with one of CH2 to CH8). (With
the ZX-LDA11/LDA41 Amplifier Units, calculations can be performed
with up to two units. Calculations cannot be performed if ZX-LDA and
ZX-LDA are used together.)
Can calculations be performed when
Sensor Heads with different measurement
ranges are connected to 2 Amplifier
Units?
Yes if the Sensor Heads are the same type (Reflective type or
Through-beam type). However, this is not true in the case of ZX-LDA11/
LDA41. Calculations cannot be performed if ZX-LDA and ZX-LDA are
used together.)
How many Amplifier Units can be
connected and communicated with ZXSF11?
In the case of ZX-LDA11-N/LDA41-N Amplifier Units, up to five units can
be connected. (In the case of the old models ZX-LDA11/LDA41, up to
two units can be connected. Communications cannot be performed if
ZX-LDA and ZX-LDA are used together.)
Is warm-up operation still required even if
LD-OFF input is cancelled?
Yes. As when the power is turned ON, warm-up operation must be
performed for about 10 minutes.

APPENDIX
Glossary
Term
Explanation
Response time
Response time is the time from when the Sensor measures a distance to when the value is
output (either as linear output or judgement output).
The response time changes depending on the settings for the number of samples to average
and calculations.
Measured value
The measured value is the measurement result displayed on the main display of the
Amplifier Unit in RUN and T modes.
The measured value is the value after all set processing has been completed, e.g., number
of samples to average, scaling, calculations, hold, and zero reset.
p.39
Present value
The present value is the current measurement result for the target Amplifier Unit.
Some set processing, such as number of samples to average, and scaling, have been
completed for the current measured value, but calculation, hold, and zero reset settings are
not reflected.
Press the LEFT or RIGHT Key in RUN mode to display the present value on the sub-display.
p.39
Linearity
The linearity is given as the error in an ideal straight line displacement output when
measuring the standard sensing object.The linearity shows how closely the linear output
maintains a linear relationship to the displacement of the sensing (i.e., it shows the accuracy
of the linear output).
Linear output
The linear output is analog data output from the linear output line.Either a current or voltage
output can be selected.
The linear output is made based on the display value and monitor focus settings.
The actual value output (the output value) can be displayed on the sub-display by pressing
the LEFT or RIGHT Key in RUN mode.
Section 7 Glossary
p.39
Judgement outputs
“Judgement outputs” is a general term for the HIGH, PASS, and LOW outputs.The
judgement outputs are made in RUN and T mode based on the display values and the
threshold, hysteresis width, and timer settings.
Smart Monitor
The Smart Monitor is software (sold separately) developed for Windows 98, 2000 and
XP.This software allows communications with ZX-LDA11-N/LDA41-N via the interface unit to
make measurement settings, save settings data, display measurement results as graphs,
and perform data logging.
For the ZX-LDA11-N/LDA41-N Smart Sensors, Smart Monitor version 3.0 or later can be
used.
p.10
Measuring range
The measurement distance is the range (distance) that measurement is possible for the
connected Sensor Head.
p.135, p.137
Sampling period
Sampling period is the time over which the sensing object is measured when the hold
function is being used.
The sampling period is determined by the trigger mode and the delay time.

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.
Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: minimum viewing distance of 13
cm between screen and cornea and a maximum viewing time of 10 s. Other viewing conditions require a comparison of the diffuse reflection exposure with the MPE.

Class
Section 7 Requirements from Regulations and Standards
162
FDA definition
Class I/1
Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared
spectra, and limits below which biological
hazards have not been established.
Class IIa/2a
Limits applicable to products whose visible
emission does not exceed Class I limits for
emission durations of 1,000 seconds or less
and are not intended for viewing.
Class II/2
Limits applicable to products that have emissions in the visible spectrum (400 to 710
nm) for emission durations in excess of 0.25
second, 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.
ZX-L-N
User’s Manual
ANSI description
A Class 1 laser is considered to be incapable of producing damaging radiation levels
during operation and maintenance and is,
therefore, exempt from any control measures or other forms of surveillance.
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 including the blink
reflex.
Section 7
Class
Class IIIa/3a
Class IIIb/3b
Class IV/4
FDA definition
ANSI description
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.
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.
Exceeding the limits of Class IIIb and are a
hazard for scattered reflection as well as for
direct exposure.
Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be
hazardous under direct and specular reflection viewing conditions, but the diffuse
reflection is usually not a hazard.
A Class 4 laser is a hazard to the eye or skin
from the direct beam and sometimes from a
diffuse reflection and also can be a fire hazard. Class 4 lasers may also produce lasergenerated air contaminants and hazardous
plasma radiation.
