Omron E3X-NH11 Fine tuning fiber photoelectric sensor Datasheet

E3X-NH
Fine Tuning Fiber Photoelectric Sensor
High-precision Sensing with Auto- and
Manual-tuning
Solves All the Problems of Conventional Models
Suitable for high-precision positioning using the
fine sensitivity adjustment function.
Manual-tuning allows threshold adjustments while
sensing objects are moving.
Operation conditions can be seen at a glance
through the incident level indicators and threshold
indicators.
Auto-tuning feature incorporates an automatic
sensitivity compensation function ensuring an
optimum margin for changes in sensing objects or
ambient environments.
Offers the longest sensing distance.
Newly added mark-sensing models (blue LED).

Note:
The sensitivity of the E3X-NH/NHB is factory-set to maximum. When resetting the sensitivity of the E3X-NH to maximum after with/
without-object teaching or positioning/no-object teaching, follow the steps described below.
1. Maximum Sensitivity Setting
1. Set the mode selector to TEACH.
Press the SET button for three seconds minimum. Be sure
that all the threshold indicators (red) are ON. The built-in
buzzer beeps once when the threshold indicators are ON.
2. With/Without-object Teaching
1. Set the mode selector to TEACH.
Locate the sensing object in the sensing area and press the
SET button once. Be sure that all the threshold indicators
(red) are ON. The built-in buzzer beeps once when the
threshold indicators are ON.
Press for 3 s min.
2. The sensitivity will be set when the built-in buzzer beeps
continuously and all the incident level indicators (green) are
ON.

executed.
1. After setting the sensitivity of the E3X-NH, select the
adjustment direction with the UP/DOWN selector in the ADJ
mode.
B. Auto-tuning (Automatic Sensitivity Compensation)
1. Set the mode selector to TEACH.
Press the SET button once without a sensing object in the
sensing area. Be sure that all the threshold indicators (red)
are ON. The built-in buzzer beeps once when the threshold
indicators are ON.

2. Press the SET button in ADJ mode. Be sure that the threshold
changes whenever the SET button is pressed. If two
threshold indicators are ON, the threshold will be set to the
middle value between the values corresponding to these
indicators.
Press for 0.5 to 2.5 s
2. Set the mode selector to ADJ and press the SET button for
three seconds minimum. Be sure that the threshold indicator
(red) flashes. The built-in buzzer beeps continuously.

Press for 3 s min.
Press for 0.5 to 2.5 s

Remove the protective cover, insert the fiber into the Amplifier, and
lower the lock button until a click is heard.
After cutting the fiber using the E39-F4 Fiber Cutter, put an insertion
mark on the fiber as a guide for correct insertion into the Amplifier,
and then insert the fiber up to this mark.
2. Disconnection
Remove the protective cover and raise the lock lever to pull off the
fiber. (Before removing the fiber, be sure to confirm that the lock is
released so as to maintain the fiber properties.)

Cutting Fiber
Insert a fiber into the Fiber Cutter and determine the length of the
fiber to be cut.
Press down the Fiber Cutter in a single stroke to cut the fiber.
An insertion mark can be placed on the fiber to serve as a reference
when inserting the fiber into the Amplifier. Use the following procedure.
Confirm through the Cutter hole that the fiber is inserted beyond the
insertion mark hole so that the insertion mark is properly indicated,
and then press firmly down on the Cutter.
Note:
Insert the fiber in the direction indicated by the arrow.
Connection
Do not pull or press the Fiber Units. The Fiber Units have a withstand force of 9.8 N (1 kgf) or 29.4 N (3 kgf) (pay utmost attention
because the fibers are thin).
Do not bend the Fiber Units beyond the permissible bending radius.
Do not bend the edge of the Fiber Units (excluding the E32-TjR
and E32-DjR).

Note: Do not mount the back part onto the mounting bracket or

mounting bracket or the DIN track, or the mounting strength
of the Amplifier Unit may decrease.

Turning the Power ON
After the E3X-NH/NHB is turned ON, the E3X-NH/NHB will be ready
to operate in 100 ms maximum. If power is supplied to the E3X-NH
and the load is connected to the E3X-NH/NHB independently, be
sure to turn ON the power supply connected to the E3X-NH/NHB
first.
When the power is turned ON, the operation indicator will be ON
momentarily. Note that this will not have an effect on performance
since no control output will be generated.
Mutual Interference Protection Function
Perform two-point teaching if two to three Fiber Units are closely
mounted together, at which time supply power only to the Unit in
teaching operation in turn or block the emitters of the Fiber Units not
in teaching operation.
EEPROM Writing Error
Write errors may result at the time of teaching due to power failure or
static noise, in which case the Unit beeps and the operation indicators flash. If any of these occur, re-input teaching using the teaching
button on the Amplifier.
Minute Sensing Object
This datasheet shows typical examples for detecting minute objects. These typical examples are for reference use only, because
these example operations were tested on Units sampled at random
from a lot and the values described are average values. Do not
assume that all Units ensure such operations.
Others
When the power is OFF:
The moment power is turned OFF, the E3X-NH/NHB may output a
pulse signal which could affect the operation of the devices connected to it. This will occur more often if power is supplied to the
E3X-NH from an external power supply, thus affecting the connected timer and counter. Use a built-in power supply as much as
possible to avoid this.
In a case where the cord is extended, use a wire with 0.3 mm2 min.
The total length of the cord should be 100 m max.
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 E3X-NH can malfunction influenced by
the switching noise of the power supply.
The supplied voltage must be within the rated voltage range. Unregulated full- or half-wave rectifiers must not be used as power supplies.
Do not lay wiring to the Optical Sensor together with power lines in
the same piping or ducts. Doing so will cause induction between the
lines, possibly resulting in faulty operation or destruction. Always
lay wiring to the Optical Sensor in separate or dedicated piping.

Applications
E39-F10 Fiber Connector
Use the following procedure (refer to the figure) to connect fibers via
the Fiber Connector.
Protective Spiral Tube
Insert a fiber to the Protective Spiral Tube from the head connector
side (screwed) of the tube.
Splice
Retention unit
Protective spiral
tube
Fiber Unit
Retention unit
Push the fiber into the Protective Spiral Tube. The tube should be
straight so that the fiber is not twisted when inserted. Then turn the
end cap of the spiral tube.
Fiber Unit
Each Fiber Unit should be as close as possible before they are connected.
Sensing distance will be reduced by approximately 25% when fibers
are connected.
Only fibers with a 2.2-mm dia. can be connected. (Refer to page 9
for applicable Fiber Units.)

Use the attached saddle to secure the end cap of the Protective Spiral Tube. To secure the Protective Spiral Tube at a position other
than the end cap, apply tape to the tube so that the portion becomes
thicker in diameter.

Reflector
Observe the Following Precautions when Using the Reflector (E39-R3)
Use detergent, etc., to remove any dust or oil from the surfaces
where tape is applied. Adhesive tape will not be attached properly if
oil or dust remains on the surface.
The E39-R3 cannot be used in places where it is exposed to oil or
chemicals.
