1.  Do not install the product in locations subjected to the following conditions:

・  

Reflection of intense light (such as other laser beams or electric arc-welding machines)

・  

Presence of dust, oil droplets or spray on the filter on the front of the Sensor Head

・  

Presence of corrosive or flammable gases

・  

Direct vibration or shock

2.  Pre-installation Checks

・  

The product cannot accurately measure the following types of objects:

(transparent objects, objects having an extremely low reflection factor, objects 

smaller than the spot diameter, objects with a large curvature, excessively 

inclined objects, etc.)

3. Wiring

・  

Avoid wiring the cable between the Sensor Head and Sensor Controller 

including this product near high voltage lines and power lines.

    Wiring them together or placing them in the same duct may cause induction, 

resulting in malfunction or damage.

・  

Before connecting/disconnecting the Sensor Head, make sure that the Smart 

Sensor is turned OFF. The Smart Sensor may break down if the Sensor Head is 

connected or disconnected while the power is ON.

4. Cleaning

・  

Do not use paint thinner, benzene, acetone or kerosene to clean the Sensor Head. 

Doing so will melt the surface of the Sensor Head.

・  

To remove dust particles, use a blower brush.

・  

To remove stubborn dirt, wipe gently with a soft cloth moistened with a small 

amount of alcohol.

5. Compatibility

・  

The Sensor Head is compatible with the Sensor Controller, and can be used if 

purchased separately.

Please observe the following precautions for safe use of the product:

1.  Do not use the product in environments where it can be exposed to 

inflammable/explosive gas.

2.  Do not disassemble, repair or modify this product.

3.  Be sure to make sure that locking mechanisms are locked before use.

4.  Dispose of this product as industrial waste.

Handling Precautions

・  

The ZS-LD 

□□

 emits a visible laser beam. Do not stare directly into the laser. 

Make sure that the laser beam path is terminated. 

A non-reflective matte painted surface is ideal at the end of the laser beam path.

If specular objects are present in the laser beam path, make sure that they are 

prevented from reflecting the laser beam. When used without an enclosure, make 

sure the laser path from eye level is avoided.

(1)Using in U.S.

        When using devices in which this product is installed in U.S., the devices are 

subjected to the U.S. FDA (Food and Drug Administration) laser regulations. 

Please inquire about details like ezport to the foreign countrry.

Laser Label Indications

The Sensor Head is supplied with labels that conform to FDA regulations. When 

this device is used in the U.S., replace the warning label on the sensor body with 

the FDA labels (supplied) referring to the figure below. Make sure that the labels 

are affixed at the correct locations as indicated.

The ZS-LD is intended to be fitted into a system as a terminal device. Follow the 

following technical standards when fitting in the device.
* FDA:21CFR

 

1040.10 and 1040.11

 

Compliance Guide for Laser Products

Attaching the ferrite core

Attach the ferrite core (provided 

with the Sensor Head) to both ends 

of the Sensor Head cable.

If the ferrite core comes loose from 

the cable, fasten the ferrite core in 

place with the Insure Lock

(supplied).

Laser Safety

Thank you for selecting OMRON product. This sheet primarily 
describes precautions required in installing and operating the 
product.
Before operating the product, read the sheet thoroughly to 
acquire sufficient knowledge of the product. For your 
convenience, keep the sheet at your disposal.

Meanings of Signal Words

Alert Statements in this Sheet

Meaning of Alert Symbols

WARNING

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.

WARNING

Never look into the laser beam. 

Doing so continuously will result in visual 

impairment. 

Do not disassemble the product. 

Doing so may cause the laser beam to leak, resulting 

in the danger of visual impairment.

Indicates the possibility of laser radiation.

Indicates prohibition when there is a risk of minor injury 

from electrical shock or other source if the product is 

disassembled.

ZS-LD50/LD80/LD200/LD130

*1  Defined as 1/e

2

 (13.5%) of the center optical intensity in the measurement center distance (effective value). The beam diameter is sometimes influenced by the ambient conditions of the workpiece such 

as leaked light from the main beam.

*2  This is the error on the measured value with respect to an ideal straight line. The standard workpiece is white aluminum ceramics. (In the regular reflection mode on ZS-LD50, the standard workpiece is 

glass.) Linearity may change according to the workpiece.

*3  This is the "peak-to-peak" displacement conversion value of the displacement output in the measuring center distance when the number of samples to average is set to 128, and the measuring mode is 

set to the high-resolution mode. The standard workpiece is white aluminum ceramics. (In the regular reflection mode on ZS-LD50, the standard workpiece is glass.)

*4  This is the typical value obtained in the measuring center distance when the sensor and workpiece are fixed by an aluminum tool.

*5  This value is obtained when the measuring mode is set to the high speed mode.

(2)Using in a country other than U.S.

   ・  

For countries other than Japan and U.S., 

warning labels must be replaced by English ones 

(supplied with the product).

   ・  

EN60825 is provided for products used in 

Europe, and the content of this standard differs.

   The ZS-LD is categorized as a Class 2 device as 

stipulated in EN60825-1 (IEC60825-1).

Various safety standards regarding laser devices are stipulated depending on the 

country of use.

The following describes the method of use according to where the product is exported.
