Oil-resistive, compact photoelectric sensor in metal housing

E3S-C

E3S-C

Features

Meets IP67/IP67G (oil tight) and NEMA 6P
standards water/oil resistance

E3S-C meets the IP67 requirements of the IEC standards and
6P of the NEMA standards. E3S-C can be used worry-free in
automotive assembly lines and other production lines where
oil vapor exists. It can also be applied to food processing lines
because it resists hydrogen peroxide, detergent and potassi­um hydroxide.

High shock resistance of 1,000 m/s

The industry's top-class photoelectric sensor features shock re­sistance of 1,000 m/s
sor at rated values, and vibration resistance of as high as 10 to
2,000 Hz.

Lineup of M12 metal connector joint type models

Lineup of water/oil/shock-resistant M12 metal connector joint
type models are available. This series ensures ease of sensor
replacement during maintenance.

NPN/PNP output selector

The operation panel has the NPN/PNP out­put selector. You need not prepare two
NPN and PNP models for export. You need
not worry about malfunctions due to noise,
either.

Mutual interference prevention enhanced
(Retroreflective, diffuse reflective models)

Fuzzy inference is introduced into the mutual interference pre­vention for the first time in the industry. This prevents a mal­function due to mutual interference, enabling two sensors to
be mounted closely side by side.

Easy optical axis alignment

OMRON's original "automatic position compensation system"
minimizes misalignment of mechanical and optical axes to
merely ±2°. The optical axis is aligned perfectly by only install­ing the sensor.

Unlike the conventional models, the E3S-C scarcely has sensitivity variations between products. Therefore, you need to make the
above adjustment on only one diffuse reflective model of E3S-CD that will be used for detection under the same conditions, and
match the indicator points of the other diffuse reflective models of E3S-CD with the above adjusted one. (You need not match the
sensitivity of each sensor.)

Precautions

Correct Use

Design

Fuzzy mutual interference prevention

When reflective photoelectric sensors are installed side by
side, one sensor may receive the light from the other sensor,
which may disturb the incident signal, causing a malfunction.
The fuzzy mutual interference prevention monitors interfering
light for a predetermined period of time before light is emitted,
and imports the interfering light level and incident frequencies
as data. Using these values, fuzzy inference is made to find
the risk of malfunction to control the light emitting timing, re­ducing the risk.

(When risk is low)
Light is emitted after interfering light is gone.

(Direct installation)
Install the E3S-C as shown below.

Wiring Considerations

Cable

• An oil-resistance cable is used to ensure oil resistance.

• The bending radius should be 25 mm or more.

Installation

Sensor installation

• Note that during the E35-C installation, hammering it will
damage the water resistance function.

• Use an M4 screw, tightened to a torque of no more than

1.18 Nm.

(When using the mounting bracket)

• To set the sensor on the mechanical axis, use the optical
axis locking holes.

• When the sensor cannot be set on the mechanical axis,
move the E3S-C vertically and/or horizontally and set it in
the center of the area where the incident indicator is turned
ON. Make sure that the stability indicator is ON.

Water Resistance

To ensure water resistance, tighten the operation panel cover
screws to 0.34 Nm to 0.54 Nm torque.

Miscellaneous

Oil resistance/chemical resistance

• Though E3S-C has a high oil resistance, it may not be able
to exhibit its performance depending on the oil type. Use oil
in compliance with the following table.

• Regarding the oil resistance of E3S-C, it has passed tests
on the oils given in the following table. Refer to the table for
examining the oil to be used.

Note: 1 . The E3S-C was immersed in the oils in the above table at 50°C for 240

hours, and passed the test of 100-M or more insulation resistance.

2 . For use in the environment where the E3S-C is exposed to the oil other

than those in the above table, use the dynamic viscosity and PH in the
above table. Pre-examine the oils since the sensor may be affected by
additives and like in the oils.
