Precautions for Safe Use
Precautions for Safe Use
Please observe the following precautions for safe use of the products.
Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/
explosive gas.
• Do not install the product close to high-voltage devices and power devices in order
to secure the safety of operation and maintenance.
Power Supply and Wiring
• The supply voltage must be within the rated range (DC12 to 24V±10%).
• Reverse connection of power supply is not allowed. Connection to AC power supply
is also not allowed.
• Open-collector outputs should not be short-circuited.
• High-voltage lines and power lines must be wired separately from this product.
Wiring them together or placing in the same duct may cause induction, resulting in
malfunction or damage.
• Always turn off the power supply before connecting or disconnecting cables and
connectors.
Others
• ZX-E series (linear proximity type), and ZX-W series (microwave type) and ZX-T
series (high-precision contact type) must not be connected. Combined use of ZX-L
with these series is not allowed.
• Do not attempt to dismantle, repair, or modify the product.
• Dispose of this product as industrial waste.

Precautions for Correct Use
Introduction
Introduction
Please observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
Installation of the Product
Installation Site
Do not install the product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Presence of corrosive or flammable gases
• 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
Precautions for Correct Use
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-XCA) 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
Precautions for Correct Use
Introduction
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
