Built-in Amplifier Photoelectric Sensor E3S-C
Water- and Oil-resistive Photoelectric
Sensor with Metal Housing Ensuring
Long Sensing Distance
Satisfies the requirements of IP67, NEMA 6P, and
IP67G (oil-tight).
Sensing distance six times as long as OMRON’s
conventional
Photoelectric Sensors ensures
stable
detection of objects.
Ensures a vibration resistance of 10 Hz to 2 kHz
and a shock resistance of 1,000 m/s2 (approxi-
mately 100G).
Incorporating an NPN and PNP output selector,
thus reducing the stock of photoelectric sensors.
Incorporating a fuzzy mutual interference preven-
tion function.
The E3S-C’s optical axis coincides with its
mechanical axis, thus ensuring axis adjustment
with ease.

Fuzzy Mutual Interference Prevention Function
If reflective Photoelectric Sensors are installed side by side, each
reflective Photoelectric Sensor may be influenced by the light
emitted
from the other Photoelectric Sensors.
The
fuzzy mutual interference prevention function of the E3S-C en
-
ables
the E3S-C to monitor any light interference for a certain period
before
the E3S-C starts emitting light so that the E3S-C can retrieve
the
intensity and frequency of the light interference as data. Using
this data, the E3S-C estimates with fuzzy inference the risk of the
malfunctioning
of the E3S-C and controls the timing of the E3S-C’
s
light
emission.
When the risk is low:
The
E3S-C waits until there is no light interference and emits light.
Light interference
Emission pattern
When
the risk is high:
The E3S-C emits light between each light interference moment.

Procedure Locate
a sensing object at the
sensing distance, set the sensitivity
adjustor to the minimum scale
position, and gradually increase
sensitivity by turning the sensitivity
adjustor clockwise until the incident
light indicator (red LED) is ON.
Position A is where the indicator has
turned ON. Regard the maximum
scale position as Position A if the
indicator does not turned ON at full
sensitivity.
Remove the sensing object and turn
the sensitivity adjustor clockwise until
the E3S-C detects the background
object and the incident light indicator
(red LED) is lit. The moment the red
light indicator is lit, stop turning the
sensitivity adjustor
, the position of
which is point B. T
urn the sensitivity
adjustor counterclockwise to decrease
the sensitivity until the red light
indicator is OFF
. The moment the red
light indicator is OFF
, stop turning the
sensitivity adjustor
, the position of
which is point C.
If there is no background object, point
C is where the sensitivity adjustor is
set to maximum.
Set the sensitivity indicator to the
position between Positions A and C
(in some cases, Positions A and C are
opposite of the above example). The
photoelectric sensor will then work
normally if the stability indicator
(green) is lit with and without the
sensing object. If it is not lit, stable
operation cannot be expected, in
which case a dif
ferent sensing
method must be applied.
Unlike
conventional photoelectric sensors, the variation in the sensitivity of E3S photoelectric sensors is minimal. This means the sensitivity
can
be adjusted on only a single photoelectric sensor
, and
then the adjustors on the other photoelectric sensors can be set to the same scale
position.
There is no need to adjust the sensitivity of each photoelectric sensor individually
.

Precautions
Connection
If the input/output lines of the photoelectric sensor are placed in the
same
conduit or duct as power lines or high-voltage lines, the photo
-
electric sensor could be induced to malfunction, or even be dam-
aged,
by electrical noise.
Either separate the wiring, or use shielded
lines
as input/output lines to the photoelectric sensor
.
The
cord connected to the E3S-C can be extended up to
100 m pro
-
vided
that the diameter of each wire of the
cord is 0.3 mm
2
minimum.
Startup Operation
A
maximum of 100 ms
is required from the time power is turned on
until
the E3S-C is able to detect objects. If power is supplied to the
loads and the E3S-C from different sources, turn on power to the
E3S-C
first.
Power Supply
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or otherwise the E3S-C may malfunction, due to the
switching
noise of the power supply
.
Water Resistivity
Do
not use the E3S-C in water
, in the rain, or outdoors.
To ensure the water resistivity of the E3S-C, tighten the screws of
the
operation panel cover to a torque of 3.5 to 5.5 kgf
S
cm (0.34 N
S
m
to 0.54 N

Oil and Chemical Resistivity
Do
not use the E3S-C in oils or liquid chemicals.
Although the E3S-C is oil-resistive, refer to the following table be-
fore 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 M
Ω
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 influ
-
ence
on the E3S-C.

JIS: Japan Industrial Standards
Cable
The E3S-C uses an oil-resistive cord to ensure oil resistivity
.
Do not allow the cable to be repeatedly bent during application.
Do not allow the cable to be bent to a radius of less than 25 mm.
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 12 kgf
S
m (1.18 N
S

maximum.
Mounting
Bracket
When
mounting the E3S-C with the mounting bracket so that sens
-
ing
objects will
be in the direction of the mechanical axis, use the op
-
tical 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 up-
wards,
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.

Malfunctioning
If
an inverter motor or servomotor is used with the E3S-C, the frame
ground (FG) terminal and the ground (G) terminal must be
grounded,
or otherwise the E3S-C may malfunction.

Optical Axis Adjustment
Direct the mounting axis of the mounting bracket in the direction
where
sensing objects will be
located. The optical axis of the E3S-C
coincides with the mounting axis of the mounting bracket, which en
-
ables
the user to adjust the optical axis of the E3S-C with ease.
Optical Lock Holes
By
tightening the optical axis lock holes with screws, the mounting
bracket
will be in the direction of the optical axis of the E3S-C.

a slit, the slit must be on the side where the lens to be used is lo-
cated.

Note: 1.
Especially take these items into consideration when replacing E3S models with E3S-C models.
2. When
connecting the E3S-C to a timer or counter with voltage input, be sure
to connect a 4.7-k
Ω
resistor between the output and
power
supply lines. When the E3S-C is turned ON, a pulse signal may be output from the sensor
.
