Optical Fiber Glossy Object Sensor
E3X-NL
Utilization lightwave technology has inno-
vated glossiness detection. OMRON's
glossy object sensor can discriminate a
wide variety of glossiness differences. The
fiber-optic system has achieved the small,
non-contact models.
Features
Employs OMRON's unique FAO (Free Angle Optics)
Two different types of fiber heads meet a wide range
technology which enables delicate sensing of object

Two different fiber heads are available.

Transparent films on boxes and labels on transparent films
can be detected.
According to applications, you can choose the short-distance,
small spot type ideal for detection of small objects or the long-
distance type that can perform in-line standard detection.

Adopts the pulse-ON system that is insensi-
tive to disturbance light
The emitter (red LED) in the fiber head uses a pulse-ON
system to minimize the influence of disturbance light. The
Sensor provides stable sensing characteristics if disturbance
light occurs from fluorescent lamps in-line.

Principles for Glossiness Detection by FAO
First, the light from a red LED passes through a polarizing fil-
ter so only the S wave is emitted.
If the detectable object is glossy, the S wave is reflected reg-
ularly and is transmitted as is to the Fiber Receiver 1.
If the detectable object is not glossy, there is more diffuse re-
flection, thus the polarization direction is randomized and a P
wave is generated.
The S and P waves are divided by the FAO (special polarized
beam splitter), the waves travel to their respective fiber receiv-
ers, and the variation in the glossiness is determined by com-
paring the two received signals.

Measures against Double Refraction
Received fiber 2
There are transparent films and transparent plastic objects that
change the direction of polarized light when it passes through
the transparent films and transparent plastic objects. This is
called double refraction. Using the optional rotary mounting
bracket (E39-L109), the sensor unit can be inclined 45 degrees
to take measures against double refraction.

Glossiness
(Example) Metal cylindrical object coated with transparent film
When light is applied to the sensing object, the reflected light
is generally a mixture of regular reflection components and
diffuse reflection components. Glossiness is directly propor-
tional to the light intensity of the regular reflection compo-
nents. In JIS, the glossiness of a glass plate surface having
1.567 reflectivity is defined 100 as the basis of glossiness.

The object can be sensed smoothly when the
angle of the sensing head is either 0˚ or 45˚.
Fuzzy Teaching Function
E3X-NL in two-point teaching operation will perform fuzzy
computation using the difference in glossiness and the differ-
ence in light energy between the two teaching points to deter-
mine the thresholds setting with E3X-NL. As shown in the
following table, if there is only a small difference in glossiness
but there is a large difference in light energy between the two
teaching points, the thresholds set with E3X-NL will be deter-
mined by the light energy values.

There are transparent films and transparent plastic objects
that change the direction of polarized light when it passes
through the transparent films and transparent plastic objects.
When E3X-NL senses these transparent films and transpar-
ent plastic objects on glossy background objects, such as
glossy paper or metals, E3X-NL will not sense these objects
smoothly in case of an incorrect angle of the sensor head. The
most suitable angle of the sensor head varies with the trans-
parent object. The angle of the sensor head can be, however,
0° or 45° for the smooth sensing of such transparent objects
due to the characteristic of polarized light. There is no need
for the angle to be midway between 0° and 45°. E39-L109,
which is sold separately, is a mounting bracket that rotates to
angles of 0° or 45° and enables E3X-NL to sense such trans-
parent objects smoothly with its sensing head set at 0° or 45°
without changing the sensing positive.

teaching error will result if the dif-
ference in glossiness and that in
light energy are both less than the

Fiber Connection and Disconnection
E3X-NL amplifier has a push lock. Connect or disconnect the
fibers to or from E3X-NL amplifier using the following proce-
dures:
One-point teaching should
be performed for the sens-
ing of different objects on a
single background object or
a single type of objects on a
variety of glossy back-
ground objects.
The operating level will be
set 15% above or below the
teaching point, depending
on the glossiness of the first
sensing object.
In general, use 2-point teach-
ing. The fuzzy teaching func-
tion (refer to Technical Guide)
is activated to set the optimum
algorithms automatically,
drawing an operation level just
about between the two points
taught.

Selection of Teaching Point(s)
Two-point Teaching
If E3X-NL is used to sense sensing objects that are only a little
different in glossiness from the background object and the
sensing objects have color patterns, the difference in glossi-
ness among the inks on the sensing objects may influence the
sensing operation of E3X-NL. Therefore perform two-point
teaching with E3X-NL at a place where E3X-NL can sense the
sensing objects smoothly while considering the characteris-
tics of glossiness versus distance of E3X-NL if the sensing po-
sition of each of the sensing objects is different from each
other.

2. Disconnection
Ensure to press the push lock again to unlock before pulling

(To maintain the fiber characteristics, remove the fiber after
making sure that the lock has been released.)

One-point Teaching
If E3X-NL is used to sense sensing objects different from
each other in glossiness on a single background object, per-
form one-point teaching with E3X-NL using the background
object. If E3X-NL is used to sense identical sensing objects on
a variety of glossy background objects, perform one-point
teaching with E3X-NL using one of the sensing objects.
3. The fiber must be locked or released in a temperature
range of -10° to 40°.
Since face-to-face isntallation of the fiber units may cause
mutual interference, mount them so that the optical axes of
the sensors are not opposed.

EEPROM Write Error
If a write error occurs (buzzer beeps, red and green teaching
indicators flicker at the same time, operation and stability indi-
cators flicker) due to power-off, static electricity or other noise
in the teaching mode (until the initial operation level compen-
sation completion of teaching without object), perform teach-
ing again with the unit button.
Note: If a memory error occurs, the red and green teaching indicators flicker at
the same time and the stability indicator flickers, unlike the teaching error.
