PRECAUTIONS ON SAFETY
SAFETY PRECAUTIONS FOR USING LASER EQUIPMENT
PRECAUTIONS FOR CORRECT USE
Checking the Package Content
Do not disassemble the product. Doing so may cause the
laser beam to leak, resulting in the danger of visual
impairment.
Indicates a potentially hazardous situation which, if
not avoided, will result in minor or moderate injury,
or may result in serious injury or death. Additionally
there may be significant property damage.
INSTRUCTION SHEET
Power Supply and Wiring
• Do not impose voltage exceeding the rated voltage: 10 to 30 VDC, including 10% ripple (p-p).
When supplying power to the Sensor, make sure that the polarity of the power is correct, and do
not connect to an AC power supply.
Do not short-circuit the load for the open collector output. Short-circuiting the load may cause
re or damage on the Sensor.
• Connect the load correctly. Short-circuiting the load may cause re or damage on the Sensor.
• Keep the load within the rated range. Overloading may result in re or damage on the Sensor.
Wire the product cable separately from high-voltage or power lines. Placing them in the same
wiring or the same duct may cause induction, resulting in the product malfunction or damage.
Always turn off the power of the Sensor before connecting or disconnecting the cable or
connector.
• Do not use the Sensor for the safety circuits in nuclear power or life-critical applications.
• Implement safety measures e.g. fail-safe circuits.
Installation
• Make sure that all installation screws must be tighten securely.
Tightening torque: M3, 0.5N·m (ZX1-LD50/ZX1-LD100)
M4, 1.2N·m (ZX1-LD300/ZX1-LD600)
Others
• 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.
Laser safety measures for laser devices are stipulated both in Japan and overseas. Here, four
cases are described.
(1) Usage in Japan
The JIS C6802:2014 standard stipulates the safety precautions that users must take according
to the class of the laser product.
The ZX1-LD is classied into class 2 dened by this standard.
The ZX1-LDL is classied into class 1 dened by this standard.
Installation Location
Do not install the product in locations subjected to the following conditions:
• Surrounding air temperature outside the rating
• Rapid temperature uctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Presence of corrosive or ammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
Reection of intense light (such as other laser beams, electric arc-welding machines, or
ultra-violet light)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray, or mist atmospheres
• Strong magnetic or electric eld
• In the water, rain, or outdoors
Power Supply and Wiring
• Do not supply the power to the Sensor before checking the I/O wiring.
• Ground the FG terminal when using a commercially-available switching regulator.
If the power supply line is subject to surges, connect a surge absorber that meets the conditions
of the operating environment.
Do not turn ON the power after wiring before making sure that the power supply is connected
correctly; there are no faulty connections, e.g. load short-circuits; the load current is correct.
Incorrect wiring may result in failure.
• Use a ZX0-XCR Extension Cable (sold separately) to extend the Sensor’s cable. Use only one
cable. Do not extend the cable for the Sensor to a length exceeding 20 m.
• The display and indicators turn ON after approx. 2.5 seconds after the power is turned ON.
The sensor is certicated by the UL standard on the assumption of the following installation
conditions.
It is based on the assumption of usage in "Class 2 circuit". Please use it with "Class 2 power supply"
in the United States or Canada. The current rating of overcorrect protection is 0.8A max.
It is certicated as open type. The sensor shall be installed within an enclosure.
Rating of the cable is 30V. Please use it as internal cable wiring only in the end products equipment.
Warming Up
After turning ON the power, allow the Sensor to warm up for approx. 30 minutes prior to use.
The circuitry is not stable immediately after turning the power ON, and the values gradually
change until the Sensor is completely warmed up. When using LD-OFF input for a long period
of time, perform warmng up for more than 30 minutes after cancelling LD-OFF.
Maintenance and Inspection
Always turn OFF the power of the Sensor before connecting or disconnecting the cable or for
making adjustment.
• Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the Sensor.
If considerable foreign matter or dust collects on the glass surface of the front of Sensor, use a
blower brush (for camera lenses) to blow off the foreign matter. Avoid blowing it off with your
breath. For a small amount of foreign matter or dust, gently wipe with a soft cloth. Do not wipe
hard. The damaged glass surface may result in detection errors.
Sensing Object
The product cannot accurately measure the following types of objects: Transparent objects,
objects with an extremely low reective sensor ratio, objects smaller than the spot diameter,
objects with a large curvature, excessively inclined objects, etc.
• Sensor: 1
• Instruction sheet (this sheet): 1 each (Japanese and English)

Fine Adjustment of Hysteresis Width
2-5
Hysteresis Width Setting
A minute step can be judged by adjusting the hysteresis width according to the
workpiece. However, note that the judgment output varies if lowering the hysteresis
width while the displacement value is varying due to moving workpiece or low
reection light intensity.
What is Hysteresis Width?
A point in which a judgment output turns from OFF to ON is called an operating
point, and a point in which a judgment output turns from ON to OFF is called a return
point. On this sensor, threshold means operating point, and a distance to the return
point can be set based on the hysteresis width.
Note that the direction where the hysteresis width is set for the threshold differs
depending on ON/OFF of the area output.

• ON and OFF are reversed after area
tuning mode without workpiece is performed.
• For area output setting, CH1 and CH2
are automatically switched.
If the zero reset memory is kept "ON",
values are written to EEPROM
(nonvolatile memory) inside the sensor
unit every time the zero reset is
performed. The EEPROM can be written
up to 100,000 times. Writing for each
measurement may result in malfunction.
Be careful of the writting life when using
the sensor with eco function ON.
When the eco function is enabled, the
display changes to the eco display,
turning OFF the digital display, if any
operation is not performed for 30 seconds
in RUN mode. The normal display returns

*1. Spot size: Defined at the 1/e2 (13.5%) of the central intensity at the measurement center distance. Measurement may be influenced if there
is light leakage outside the defined region and the surroundings of the target object have a high reflectance in comparison to the target
object. Correct measured values may not be obtained if a workpiece with smaller diameter than the spot size is detected.
*2. It shows the error in relation to the ideal curve of the displacement output when measuring OMRON's standard physical object (white
ceramic) under the environment at 25°C.
*3.
Temperature characteristics at the center of sensing distance when the space between the sensor and workpiece is locked with aluminum jig.
*4. Static definition with the background suppression function ON for tuning with STND mode and standard white ceramic.
*5. Connector-joint model cable: Use it together with a 10 m or 20 m extension cable.
*6. The connector joint model connector section can achieve IP67 if it is connected via an extension cable.
