Alert Statements

Explanation of signs

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.

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.

PRECAUTIONS FOR SAFE USE

Please observe the following precautions for safe use of the products.
(1)Installation Environment

Do not use the product in environments where it can be exposed to inflammable/explosive gas.

To secure the safety of operation and maintenance, do not install the product close to 

high-voltage devices and power devices.

(2)Power Supply and Wiring

Be sure to use a dedicated amplifier unit (E3NC-SA

□□

/E3NC-SA0). Connecting the sensor 

to other amplifier unit may cause damage or fire.

When short circuiting the cable, be sure to connect wires correctly according to the 

specification. Improper connection may cause damage or fire.

High-Voltage lines and power lines must be wired separately from this product. Wiring them 

together or placing them in the same duct may cause induction, resulting in malfunction or 
damage.

Unit: mm

Please observe the following precautions to prevent failure to operate, malfunctions, or undesirable 
effects on product performance.
(1)Do not install the product in locations subjected to the following conditions:

Surrounding air 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

Reflection 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 field

(2)Warming Up

The circuitry is not stable immediately after turning the power ON, and the values gradually 

change until the Sensor Head is completely warmed up.

(3)Maintenance and inspection

Always turn off the power of the unit before connecting or disconnecting cables.

Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the sensor.

If considerable foreign matter or dust collects on 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. If the surface 
is damaged, false detection may result.

(4)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.

 Shortening the connection cable for use

SAFETY PRECAUTIONS FOR USING LASER EQUIPMENT

The E3NC-LH use a laser as the light source. Lasers are classified based on EN standard (EN 
60825-1)

・ 

E3NC-SH

@@

 Sensor Head: Class 1

Using in Europe
The E3NC-SH is categorized as a Class 1 device as stipulated in EN60825-1.

The E3NC-SH has the WARNING label 
regarding laser on the side of the Sensor Head as 
shown on the right figure.

When using devices in which E3NC-SH is installed 
in the U.S., the devices are subjected to the U.S. 
FDA (Food and Drug Administration) laser 
regulations. E3NC-SH series is classified into Class1 
by the standard of IEC/EN60825-1 according to 
deviations of Laser Notice NO.50 of this standard, 
and is scheduled to report to CDRH (Center for 
Devices and Radiological Health).

Push the operation lever at the operation slot with the slotted 
screwdriver and pull out the wire to adjust the cable length.
The tip of the screwdriver must be 2 mm or less. The type of 
screwdriver whose tip width becomes broaden toward its root 
cannot be used.

(3) Push the slotted screwdriver all the way to the releasing slot 

and pry the slotted screwdriver up and down lightly. When you 
feel a click on the slotted screwdriver, pry it to the reverse 
direction of the wire insertion direction. The operation lever will 
recover with a click sound.

(4) Check that the operation lever recovers and the wire coating 

enters into the wire insertion slot. The shield wire cover must 
not be shorted circuited. (The wires are connected when you 
pull the wire and feel a resistance.)

(1) According to "STRIP GAUGE" shown on the side of the 

product, strip the coating of the shield for 20 mm or less, strip 
the coating of the core wire for 7 to 8 mm, and twist the wire 
for several times.

(2) Inser t the wire all the way to the wire 

inser tion slot. Make sure that the wire 
coating is located inside the wire insertiong 
slot and the tip of the conductor passes 
through the connection part. Connect wires 
as follows. Terminal No.1: Shield (Red, 
White sides), No.2: White, No.3: Red, No.4: 
Brown, No.5: Blue, No.6: Shield (Brown,

1. The E3NC-SH is classified into Class 1 by the standard of EN60825-1 according to deviations of Laser Notice No.50 

of FDA standard, and will be reported to CDRH (Center for Devices and Radiological Health).

2. Measured using Omron’s reference sensing object (white paper).

3. Defined at the 1/e

2

 (13.5%) of the central intensity at the measurement  distance. Measurement may be influenced if 

there is light leakage outside the defined region and the surroundings of the target object have a high reflectance in 

comparison to the target object. Also, when detecting a workpiece that is smaller than the spot size, a correct value 

may not be obtained.

Connector cover: White

The connector cover of E3NC-SH is white.
Connect the cable correctly.

<Detection Near the Wall Surface>

<Detection of Workpiece with Level Difference>

<Cavity Detection>

Stable detection is possible 
regardless of level difference.

Level difference may cause 
an abnormal detection value.

The Sensor is less 
influenced by ambient 
lighting.

The Sensor is easily influenced by 
ambient lighting, which may cause 
detection value variations. *

Detection is not possible if 
the emitter or receiver section 
is blocked. 

 Caution on Mounting Direction

*

Before performing tuning, apply mat paint on the wall surface or turn ON the background suppression 

   function to avoid laser light reflection.
