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.

6.  Cable extend

  This product can't be connected to long extension cables for sensor head (Model 

ZS-XC

□□

CR, Model ZS-XC02D and Model ZS-XEQ).

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.

PRECAUTIONS FOR SAFE USE

PRECAUTIONS FOR CORRECT USE

Handling Precautions

  The ZS-HLDS2V/HLDS2VT 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.

Export and Trade Control Laws

The ZS-HLDS2V is classed as a commodity (or technology) requiring acquisition 

of export permission in accordance with foreign exchange and overseas trade 

control laws. When the ZS-HLDS2V is to be taken outside of Japan, adopt the 

required procedures such as application for export permission by the Japanese 

government.

* Contact your OMRON representative.

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

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-HLDS2V/HLDS2VT

*1 Defined as 1/e

(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 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 glass. The minimum resolution of ZS-HLDS2VT is 0.25

μ

m regardless of average count setting. 

*4 This is the typical value obtained in the measuring at 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-HLDS2V/HLDS2VT is categorized as a Class 2 device as 

stipulated in EN60825-1 (IEC60825-1).
