Laser Safety
The ZX-LD@@, ZX-LD@@L, ZX-LD@@V, and ZX-LD@@VL Sensor 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 ZX­LT @@@ Sensor Heads are Class 1 and Class II Laser Products, respec- tively. The ZX Series is meant to be built into final system equipment. Pay special attention 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 operation manual. Otherwise, you may
be exposed to hazardous laser radiation.
(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 terminated 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 terminating 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 displace nor remove
the protective housing during operation, maintenance, and any other servic-
ing. (4) The user should return the product to OMRON for all repair and servicing. (5) As for countries other than those of Europe and the U.S.A., observe the regu-
lations and standards specified by each country.

Precautions
Ratings and Performance
(1) Conform to the specified ratings and performance.
Refer to "6-1 Ratings/Specifications"
• Do not impose voltage exceeding the rated voltage, otherwise the Sen­sor may be damaged.
• 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.
• Do not short-circuit the load for the open collector output, otherwise the Sensor may be damaged.
(2) Do not disconnect the connector connecting the Sensor Head and the con-
troller while power is being supplied, otherwise the Sensor may be damaged.
(3) Allow a warm-up period of approximately 10 minutes after turning ON the
power supply.
(4) Objects of certain materials or shapes may not be detectable, or the detec-
tion accuracy may not be sufficiently high. These include materials that are transparent or have extremely low reflectivity, and objects that are smaller than the Sensor’s spot diameter or have extreme curvature or inclination.
Power Supply and Wiring
(1) 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.
(2) The total length of the Sensor cable or Amplifier cable must be 10 m or less.
Use an ZX-XC@A Extension Cable (order separately) 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.
(3) Do not lay a power supply cable for the ZX together with high-voltage lines or
power lines to prevent interference, damage, and malfunction.
(4) When using a commercially available switching regulator, ground the FG
(frame ground) terminal.
(5) If the power supply line is subject to surges, connect a surge absorber that
meets the conditions of the usage environment.
(6) When using a Calculating Unit, connect the corresponding linear ground of
the Amplifier Unit.
Environment
(1) Do not use the Sensor in strong electromagnetic fields or in an environment
where the operation of the Sensor is subject 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.
xi
Precautions
• Locations subject to direct sunlight or near heating equipment.
• 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.
Maintenance
(1) Always turn OFF the power supply before adjusting or removing the Sensor
Head.
(2) 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.
• 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.
• 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.
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.
Controlling Mutual Interference
Mutual interference can be prevented when using two Sensor Heads together, by connecting the ZX-CAL Calculating Unit between the two Amplifier Units. However, this effect cannot be attained if the laser beam of one Sensor Head is received when the other Sensor Head is approaching saturation. When considering the use of the ZX-CAL Calculating Unit to control mutual interference, confirm the operation with actual Units in advance.
Applicable standards
• EN61326-1
• Electromagnetic environment: Industrial electromagnetic environment
(EN/IEC 61326-1 Table 2)
• There may be cases that current output or voltage output fluctuate within ±3 times of resolution when a sensor is experienced electromagnetic interference.

Refer to 3-2 Hardware Functions for I/O functions.
Note 1. Use a separate stabilized power supply for the Amplifier Unit, particu-
larly when high resolution is required.
2. Wire the Unit correctly. Incorrect wiring may result in damage to the Unit. (Do not allow the I/O lines, particularly the linear output, to come into contact with other lines.)
3. Use the 0-V ground line (blue line) for the power supply and use the shield wire (linear output ground) together with the linear output (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 output ground to the 0-V ground line.

1-4 Connections
1-4-1 Sensor Head and Amplifier Unit
1. Insert the output cable connector of the Sensor Head into the in­put cable connector of the Amplifier Unit until the connector ring locks into place.
2. When disconnecting the Sensor Head, hold the connector ring and Amplifier Unit connector and pull them straight out.
• Do not pull only on the connector ring, because the input cable of the Amplifier Unit may be damaged.
• Do not touch the pins or contacts inside the connectors.
1-4-2 Connecting Cable and Sensor Head
This procedure is necessary for Through-beam Sensor Heads only.
1. Insert the emitter-side and receiver-side connectors from the Sensor Head into both the emitter-side and receiver-side con­nectors on the Connecting Cable until they lock in place. Connect the gray cables for the Emitter and the black cables for the Receiver.
2. When disconnecting the Sensor Head, detach the emitter-side and receiver-side connectors on the Connecting Cable from the emitter-side and receiver-side connectors on the Sensor Head cables and then pull them straight out.
• Do not touch the pins or contacts inside the connector.
• Never allow the connectors to be subjected to electrostatic charges.

1-4-3 Extension Cables
When extending Sensor Head and Amplifier Unit cables, use the following special cables (order separately).
• 1-m Cable: ZX-XC1A
• 4-m Cable: ZX-XC4A
• 8-m Cable: ZX-XC8A
• 9-m Cable: ZX-XC9A (for use with Reflective Sensors only) Connect the Extension Cable between the Connecting Cable and the
Amplifier Unit.
Note: Never use two or more Extension Cables to extend the cable length.
1-4-4 Amplifier Units and Calculating Unit
1. Open the connector covers on the Amplifier Units by lifting and
slide them open.
2. Mount the front section of the Calculating Unit to the DIN Track.
3. Slide the Calculating Unit on the DIN Track until the Calculating
Unit connector connects securely to the connector on the first Amplifier Unit. The connectors should click into place.

Connections Section 1-4
4. Slide the other Amplifier Unit on the DIN Track until the Calculat­ing Unit connector connects securely to the Amplifier Unit con­nector. The connectors should click into place.
Note 1. Connect the connectors only after mounting the Units to the DIN
Tr ac k .
2. Use an PFP-M End Plate when necessary to prevent the Amplifier Units from moving (e.g., as a result of vibration).
