Ultrasonic Displacement Sensor
E4PA-N
Now, more advanced with a new
mutual interference prevention
function.

Application Examples
Detecting slackness in sheet
materials
Detecting liquid levels
Remotely detecting LCD
wafers
Detecting dies
Features
■ High-precision detection with a
wide range of measurements.
Four types of Sensors are available with max-
imum sensing distances of 0.5 m, 2 m, 4 m,
and 6 m. With the 0.5-m type, a repeat accu-
racy of 1 mm or better has been achieved.
■ The Sensor is ultrasonic, so it is not affected by the
color of objects.
A variety of materials can be measured, including transparent and
reflective objects. Measurements are performed with no contact, so
even highly-viscous liquids are no problem.

■ A setting plug with a temperature compensation
function makes it easy to set the sensing range.
The sensing range can be set by the Setting Plug,
which is included with the Sensor. No special con-
troller is required. The Setting Plug’s built-in tem-
perature sensor provides superior temperature
characteristics of ±1% FS.

■ The mutual interference prevention function allows
up to five Sensors to be used in close proximity.

Operation
www.DataSheet4U.com
Setup and Operating Procedure
The E4PA-N is factory-set for the decrease mode for analog output characteristics and for the maximum sensing range. These settings enable
scaling with the connected device (e.g., the K3NX). In this case, only step 4 is required.
To change the analog output range, follow steps 1 to 4 below.
1. Preparation for Setup
Step
Setting/Operation
3. Setting Analog Output Characteristics
Mode
1 Remove the Setting Plug.
Step
Setting/Operation
2 Turn ON the power.
(See note.)
1 Insert the Setting Plug at the E2/E3
position. (Align the notch on the Sen-
sor with the E2/E3 triangular mark on
the Setting Plug.)
E2/E3 position
3 Proceed to Step 2 Setting Sensing Range.
Note: Do not insert the Setting Plug yet. It must be inserted within
five minutes after the power is turned ON, however, or the set-
up will not be possible. If that happens, power up again and
start over.
2. Setting Sensing Range
Step
1
Setting/Operation
Place the sensing object at the nearest point within the sensing
range.
Sensing object
50 mm (for E4PA-LS50-M1-N)
2 Insert the Setting Plug at the A1
position. (Align the notch on the
Sensor with the A1 triangular mark
on the Setting Plug.)
A1 position
The power indicator (green) and
the A1 RUN indicator (yellow) with
flash, showing that the near dis-
tance has been correctly set.

A1 A2
3 Remove the Setting Plug. (In this
state, the setting is confirmed and
recorded.)
4 Place the sensing object at the farthest point within the sensing
range.
A2 RUN indicator (yellow) flashing:
● Analog output characteristics: Decrease mode
In this mode, the analog output decreases
(20 to 4 mA/10 to 0 V) as the
sensing object nears the E4PA
E2
E3
within the sensing range.
A1 A2
The mode changes when the Setting Plug
is reinserted at the E2/E3 position.
A1 RUN indicator (yellow) flashing:
● Analog output characteristics: Increase mode
In this mode, the analog output
increases (4 to 20 mA/0 to 10 V)
as the sensing object nears the
E2
E3
E4PA within the sensing range.
A1 A2
The mode changes when the Setting Plug
is reinserted at the E2/E3 position.
A1 and A2 RUN indicators (yellow) flashing at the same time:
● Analog output characteristics: Output from 0 mm
In this mode, the analog output
decreases (20 to 4 mA/10 to 0 V)
as the sensing object nears the
E4PA between the farthest
E2
E3
sensing point and 0 mm.
A1 A2
Sensing object
500 mm (for E4PA-LS50-M1-N)
5 Insert the Setting Plug at the A2
position. (Align the notch on the
Sensor with the A2 triangular mark
on the Setting Plug.)
A2 position
The power indicator (green) and
the A2 RUN indicator (yellow) will
E2
flash, showing that the far distance
has been correctly set.

A1 A2
6 Remove the Setting Plug. (In this
state, the setting is confirmed and
recorded.)
7 Proceed to Step 3 Setting Analog Output Characteristics Mode.
Note: Check the input impedance of connected devices
and the analog output in Ratings/Characteristics (see
page 2).
2 After the analog output characteristics have been set, remove the
Setting Plug.
3 Proceed to Step 4 Setting Temperature Compensation Mode.
4. Setting Temperature Compensation Mode
Step
1
2
Setting/Operation
Insert the Setting Plug at the T posi-
tion. (Align the notch on the Sensor
with the T triangular mark on the Set-
ting Plug.)
T position
Leave the Setting Plug inserted where it is. (This completes the set-
up.)
Note: To maintain the temperature compensation, leave
the Setting Plug inserted during operation. If it is re-
moved from the E4PA, the temperature compensa-
tion will be disabled.
Note: If the reflection from the Sensor is extremely weak, or if the sensing object is set outside of the sensing range, the error indicator (red) will
flash to show that the sensing range is not accurately set. If the Setting Plug is left removed for five minutes or longer, temperature com-
pensation will be disabled (status before setting).
If it becomes necessary to change the settings for step 2 (Sensing Range) or step 3 (Analog Output Characteristics Mode) after steps 1 through
4 have been completed, the contents of all the previous settings will be remembered, so only the items to be changed need to be reset. Go
through the steps in order, from 1 to 4, and reset only the items to be changed.
