PRECAUTIONS ON SAFETY
● Meanings of Signal Words
Indicates a potentially hazardous situation which, if
not avoided, will result in minor or moderate injury,
WARNING
or may result in serious injury or death. Additionally
there may be significant property damage.
● Explanation of Signs
● Laser beam
Indicates caution on potential laser beam hazard.
● Do not disassemble
Indicates prohibition when there is a risk of minor injury from
electrical shock or other source if the product is disassembled.
● Alert Statements
WARNING
Do not expose your eyes to the laser radiation either directly
(i.e., after reflection from a mirror or shiny surface). Loss of
sight may possibly occur in case of the exposure to laser
high power density.
Do not disassemble the product. Doing so may cause the
laser beam to leak, resulting in the danger of visual
impairment.
SAFETY PRECAUTIONS FOR USING LASER EQUIPMENT
The ZX1-LD uses a laser as the light source. Lasers are classi ed based on EN standard (EN 60825-1)
■ Labeling on Laser Use
The ZX1-LD has the following WARNING label or explanatory label on the side of the sensors.

PRECAUTIONS FOR SAFE USE
The following precautions must be observed, since they are essential to ensure safety in operation.
■ Installation Environment
• Do not use the Sensor in locations subject to explosive or ammable gases.
• To ensure safety in operation and maintenance, do not install the Sensor near high-voltage
equipment or power devices.
■ 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.
PRECAUTIONS FOR CORRECT USE
■ 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-XC□R 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.
■ 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.
