Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
• Also, mount the Sensor so that it is not aligned with extreme
changes in color or materials, as shown below.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the product in atmospheres or environments that exceed
product ratings.
● Designing
Cable
The E3S-CL2 uses an oil-resistive cord to ensure oil resistivity.
● Mounting
Mounting
Direction of
movement
• Mount the Sensor so that sunlight, fluorescent light, incandescent
light, or other strong sources of light do not enter the directional
angle of the Sensor.
Mounting Direction
• Mount the Sensor so that the sensing
face runs parallel to the surface of the
object being detected as shown
below, and not at an angle.
Sensing side
Precautions
• When mounting the Sensor, do not hit the Sensor with a hammer,
or the Sensor will lose its watertightness.
• Use M4 screws to mount the Sensor.
• The tightening torque of each screw must be 1.2 N·m maximum.
Surface of
sensing object
● Others
Oil and Chemical Resistivity (E3S-CL2)
The E3S-CL2 was tested for resistance to the oils given in the
following table. Refer to the information in the table when deciding
which type of oil to use. However, performance may be affected by
certain types of oil.
If detecting a shiny object, however,
mount the Sensor so that the sensing
face is at an angle of between 5° and
10° of the surface of the object being
detected as shown below, and check
to be sure that there is no
interference from the background.

an angle as shown below, and separate the Sensor as far as
possible from the mirror surface.

Note: 1. The E3S-CL2 maintained a minimum insulation resistance of 100 MΩ
after it was dipped in all the above oils at a temperature of 50°C for 240
hours.
2. When using the E3S-CL2 in environments subject to oils other than
those listed above, use the figures for kinematic viscosity and ph
values from the table as general guidelines. Additives and other
substances contained in oils may affect the E3S-CL2. Be sure to
consider this before use.
