Built-in Amplifier Photoelectric Sensor
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
detection of objects.
Ensures a vibration resistance of 10 Hz to 2 kHz
and a shock resistance of 1,000 m/s
mately 100G).
Incorporating an NPN and PNP output selector,
thus reducing the stock of photoelectric sensors.
Incorporating a fuzzy mutual interference prevention 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
emission.

Set the sensitivity indicator to the

(in some cases, Positions A and C are
opposite of the above example). The
photoelectric sensor will then work
normally if the stability indicator

sensing object. If it is not lit, stable
operation cannot be expected, in
which case a dif

method must be applied.
which is point C.
If there is no background object, point
C is where the sensitivity adjustor is
set to maximum.
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
position.
There is no need to adjust the sensitivity of each photoelectric sensor individually
, and
then the adjustors on the other photoelectric sensors can be set to the same scale
.
