E3S-C
Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use the product in atmospheres or environments that exceed
product ratings.
● Wiring
Cable
• The E3S-C uses an oil-resistive cable to ensure oil resistivity.
• Do not allow the cable to be bent to a radius of less than 25 mm.
● Mounting
Mounting
• When mounting the E3S-C, do not hit the E3S-C with a hammer, or
the E3S-C will loose watertightness.
• Use M4 screws to mount the E3S-C. The tightening torque of each
screw must be 1.18 N·m maximum.
Mounting Bracket
• When mounting the E3S-C with the mounting bracket so that
sensing objects will be in the direction of the mechanical axis, use
the optical axis lock holes.
• If it is not possible to mount the E3S-C so that the sensing objects
will be in the direction the mechanical axis, move the E3S-C
upwards, downwards, to the left, or to the right and secure the E3S-
C in the center of the range where the light indicator will be lit, at
which time make sure that the stability indicator is lit.
Direct Mounting
Mount the E3S-C as shown in the following illustration.
Mounting with M4 Screws
Mounting with M3 Screws
Optical Axis Adjustment
Optical Lock Holes
By inserting screws into the
optical axis lock holes, the
Mounting Bracket will be in the
direction of the optical axis of the
E3S-C.
● Adjusting
Optical Axis of Through-beam Sensor
The E3S-C Through-beam Models incorporates two lenses, one of
which will be used as shown in the following illustration. When using
a Slit, the Slit must be on the side where the lens to be used is located.

Water Resistance
To ensure the water resistance of the E3S-C, tighten the screws of the
operation panel cover to a torque of 0.34 N·m to 0.54 N·m.
● Others
Oil and Chemical Resistance
• Although the E3S-C is oil-resistance, refer to the following table
before using the E3S-C in places where oil may be sprayed on the
E3S-C.
• Tests were carried out with the following oils and it was certified that
the E3S-C resists these oils.
Note: 1. The E3S-C maintained a minimum insulation resistance of 100 MΩ
after the E3S-C was dipped in all the above oils at a temperature of
50°C for 240 hours.
2. When using the E3S-C in a place where an oil other than the ones
listed above is sprayed on the E3S-C, refer to the above kinematic
viscosity and ph values. The location may be suitable for the E3S-C if
the kinematic viscosity and pH values of the oil are close to the above
kinematic viscosity and pH values, but make sure that the oil does not
contain any additive that may have a negative influence on the E3S-C.
