E3X-DA
Digital Fiber Amplifier Provides High
Performance and Ease of Use
First amplifier to offer three
user-selectable displays: digital level,
percentage and analog display
Flashing LED and digital display of light
intensity simplifies optical axis alignment
Reverse mode sets the digital display to
read right-side-up regardless of
amplifier orientation
Adjustable off-delay timer (0 to 200 ms)
Three setting modes let users choose
the ratio of response speed to sensing
distance: standard sensing distance
(400 mm), long sensing distance
(500 mm) and high speed (250 s)
12-bit A/D converter ensures high
resolution for precise detection and
differentiation

DISPLAY AND SPECIAL FUNCTION SETTINGS
Display Setting
The E3X-DA offers three display modes, which are Digital Incident Level display, Digital Percent display and Analog display.
•
•
•
Digital Incident Level Display: the incident level is digitally displayed.
Digital Percent Display: the threshold-based excess gain is displayed in percentage.
Analog Display: threshold and excess gain is displayed by two-color (red and green) bar graph.
Special Function Setting
The E3X-DA series has various functions that give users more flexibility in meeting a variety of application requirements.
•
•
•
•
•
Sensing Function: Enables users to choose either standard sensing distance mode (400 mm), long sensing distance mode
(500 mm) or high speed mode (response time = 250 s)
Timer Function: Enables users to select various OFF-delay timer settings from (0 to 200 ms). OFF-delay timer lengthens the duration of a short, high-speed signal so that it can be recognized as input to Programmable Controllers during a scan cycle.
Flashing Function: Flashing red LED allows easier optical axis adjustment.
Display Hold Setting: This function provides easy data reading during optical axis adjustment and high-speed detection by holding
the displayed value for a period of time. Displayed data gets updated every 2 seconds. Within the 2-second timeframe, the maximum
or minimum value is displayed (data will be flashing).
Display Orientation Setting: Reversible digital display provides easy data reading from any mounting orientation.

By pulling back the lock (yellow) on the bottom with a flat blade
screwdriver, the amplifier can be removed easily.
In the case of side mounting, attach the mounting bracket on the
amplifier first, and secure the amplifier with M3 screws and
washers. The diameter of the washers should be no more than

Bending Radius
Do not pull or press the fiber units. The fiber units have a
withstand force of 9.8 N or 29.4 N (pay utmost attention because
the fibers are thin).
E39-F11 Sleeve Bender
Do not bend the fiber unit beyond the permissible bending radius.
Do not bend the edge of the fiber units (excluding the E32-TR
and E32-DR).
The bending radius of the stainless steel tube should be as large
as possible. The smaller the bending radius becomes, the shorter
the sensing distance will be.
Insert the tip of the stainless steel tube to the Sleeve Bender and
bend the stainless steel tube slowly along the curve of the Sleeve
Bender (refer to the figure).

Precautions
AVOID DAMAGE TO THE E3X-DA
WIRING
•
•
Cable
•
•
•
•
•
•
Voltage must not exceed the rated voltage of the E3X-DA.
When supplying power to the E3X-DA, make sure that the
polarity of the power is correct.
Do not short-circuit the load connected to the E3X-DA.
Do not impose 100 VAC or more on models that operate
with DC.
Do not use the E3X-DA in environments where flammable or
explosive gas exists.
Do not disassemble, repair or modify the E3X-DA.
The E3X-DA has an enclosure rating of IP50; do not immerse
in water.
Load must be connected to the E3X-DA.
•
•
The cable can be extended up to 100 m provided the wire
thickness is at least 0.3 mm2.
Do not pull cables with pulling force exceeding 50N.
Avoid Damage or Malfunction Due to Induction Noise
•
Never run the E3X-DA cables in the same conduit with power
lines or high tension cables.
Mutual Interference Protection Function
•
Perform two-point teaching if two or three fiber units are
closely mounted. Only apply power to the unit that is in
teaching operation or block the emitters of the fiber units that
are not in teaching mode.

The E3X-DA is ready to sense objects 100 ms after the unit
is turned on.
If power is supplied to the E3X-DA and the load
independently, make sure to turn ON the E3X-DA first.
When the E3X-DA is turned ON or OFF, the operation indicator will be illuminated for an instant, but no control output will
be turned ON.

An EEPROM error may result if power failure or static noise
occurs. In this case, repeat the whole teaching procedure.

Do not connect the E3X-DA to a full-wave or half-wave
rectified power supply.
When a standard switching power supply is used, the frame
ground (FG) and the ground (G) terminal must be grounded.
