A panel mounting bracket MS-DP-1 is
enclosed to enable simple mounting of
the sensor onto the panel surface, thus
contributing to the total cost reduction.
Light-weight, compact design Can be mounted closely Bright, easy to view two-color digital display
A compact form specifically designed
for mounting on an equipment panel.
It only uses half the space of our
conventional product and provides the
lightest weight in the industry of just
30 g (cables excluded).
Even when you use more than one
sensor at the same time, you can
mount them close together in one hole
to save both space and man-hours.
The digital display is a large, easy-to-
view, and two-color digital display. It is
also functions as an output indicator as
it changes from green to red color
when the output turns ON, enabling
you confirm the output status at a
glance.

Snap-fit connector is used for cable connection
The cable has a snap-fit connector for
easy mounting and removal. The
connector can be easily assembled by
yourself.
Further, the connection by connector
eliminates waste and is eco-friendly.
Usable with a panel thickness of 1 to 6 mm 0.039 to 0.236 in Supplied with a simple-to-mount panel mounting bracket
Since the panel thickness can be from 1 to
6 mm 0.039 to 0.236 in, the sensor can even
be mounted on thick, resin-made panels.
Two types of sensor mounting brackets available
The MS-DP-3 bracket, enabling vertical
mounting, and the MS-DP-4, enabling
horizontal mounting, are available as
options. One-touch mounting of the
sensor mounting brackets is possible
with the panel mounting bracket included
with the sensor.

APPLICATIONS
Checking IC absorption Checking degree of vacuum for vacuum molding Checking reference pressure of device
DP4-50
DP4-50
DP4-52
Can be mounted on a DIN rail
Change-over to analog bar display possible
The sensor can be mounted even on a 35 mm 1.378 in width DIN rail by using the
optional DIN rail mounting bracket (MS-DP-2).
It can be mounted in a narrow space inside of your device.
The pressure changes can be
indicated as a bar display. The analog
bar color reflects the changes in the
output. (The detected pressure value
is displayed in steps of 14 % F.S.
approx.)
Flexible control with four output modes
 100 kPa compound pressure type available
To serve a broad range of pressure
needs, we offer 100.0 kPa, compound
pressure type, in addition to the 0 to
101.3 kPa and 0 to 1.000 MPa types.
Incorporated with the memory bank function
You can store two patterns of set
values. Hence, the setup can be
changed by a single touch.
Selection from six pressure units
The pressure unit can be selected from six
different systems to suit your requirement.
The selectable pressure units differ
with the sensor type. When the
pressure unit is changed, the
measured pressure value and the set
values are automatically converted.
MS-DP-2
High speed response of 2 ms or less
The sensor has a high speed response of 2 ms
or less.
In addition, the sensor has a chattering
prevention function. This allows change-over
of the response time so that fluctuation of the
reference pressure generated during operation
of the large-diameter cylinder and the ejector is
not detected as an abnormal pressure.

Conditions in use for CE conformity
• The DP4 series is a CE conformity product complying with
EMC Directive. The harmonized standard with regard to
immunity that applies to this product is EN 61000-6-2
(Note) and the following condition must be met to conform
to that standard.
Condition
Wiring
•
Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power
supply is connected to an actual ground.
• In case noise generating equipment (switching regulator,
inverter motor, etc.) is used in the vicinity of this sensor,
connect the frame ground (F.G.) terminal of the equipment to
an actual ground.
• If the used power supply generates a surge, connect a surge
absorber to the power supply to absorb the surge.
• Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause
malfunction due to induction.
• In order to reduce noise, make the wiring as short as possible.
Others
•
Use within the rated pressure range.
• Do not apply pressure exceeding the pressure withstandability
value. The diaphragm will get damaged and correct operation
shall not be maintained.
• Do not use during the initial transient time (3 sec. approx.)
after the power supply is switched on.
• Avoid dust, dirt, and steam.
• Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
• Do not insert wires, etc., into the pressure port. The
diaphragm will get damaged and correct operation shall not
be maintained.
• Do not operate the keys with pointed or sharp objects.

from the power supply.
Note: The EN 50082-2 that previously applied to the products for conforming
to EMC Directive was replaced by EN 61000-6-2 starting April 1st,
2002.
Error messages
•When an error occurs, take the following corrective action.
Switch off the power
supply and check the load.
Applied pressure at the

adjustment should be
done again.

PRECAUTIONS FOR PROPER USE
Peak hold & bottom hold functions
• Peak hold and bottom hold functions enable the display of
the peak value (maximum pressure value) and the bottom
value (minimum pressure value) of the varying measured
pressure.
These functions are convenient for finding the pressure
variation range or for determining the reference for
pressure settings.
•Please note that the peak value and the bottom value data is
erased when it is no longer displayed.
• Since the key-protect information is stored in an EEPROM, it
is not erased even if the power supply is switched off.
• Please take care to remember if the key-protect function has
been set.
• In the sensing mode, press key contin-
uously for 4 sec, or more, and release it
immediately when is displayed.
Key-protect is released and the sensor returns to
the sensing mode.
Release of key-protect
• When the keys are to be operated, make sure that key-protect
is released.
Forced output mode
•In the initial setting mode, if the output mode is set to the
forced output mode ( ), the output is forcibly maintained
at OFF level in the sensing mode, irrespective of Set Value
1 to 3 (P-1 to P-3).
Further, if the keys are operated as per the procedure
given below, the output can be forcibly switched either ON
or OFF without applying pressure at the pressure port. This
is convenient for an operation check of the comparative
output or for an inspection before commencing work.
The diagram below appears when the DP4-50(P) has been used to
set the display to ‘Digital display’( ).
• In the sensing mode, press key to change
to the forced output mode.
• Whenever UP key is pressed, the output state
switches to either ON and OFF alternately.
• Press key to return to the sensing mode.

Memory bank function
• The memory bank function is a function which allows two
types of output to be stored: Set Values 1 to 3 (P-1 to P-3)
and Set Values 4 to 6 (P-4 to P-6).
This make it possible to change set values quickly.
• If the key is pressed in a sensing mode
other than forced output mode, the mode will
change to pressure value setting mode.
• After releasing the mode select key, press the
key again continuously until is
displayed (4 sec. or more).
• Make the setting for Set Values 4 to 6 (P-4 to
P-6). Set Values 4 to 6 (P-4 to P-6) correspond
to Set Values 1 to 3 (P-1 to P-3) respectively.
Refer to 4Pressure value setting on p.786
for details on making each setting.
• Output is kept off at the point where the mode is changed from
another output mode to forced output control mode ( ).
• Even if output has been set to stay on during forced output
control mode, it will be forcibly changed to off at the point
where the mode changes back to sensing mode.

Key-protect function
• Key-protect is a function which prevents any unintentional
change in the conditions which have been entered in each
setting mode by making the sensor not to respond to the
key operations.
• In the sensing mode, press key contin-
uously for 4 sec, or more, and release it
immediately when is displayed.
Key-protect is set and the sensor returns to the
sensing mode.

Piping
• When connecting a commercial M5 coupling to the
pressure port, hold the flat sides of the pressure port with
a 13 mm 0.512 in spanner and make sure that the
tightening torque is 1Nm or less.
If excessive tightening torque is applied, the commercial
fitting may break.
Mounting
• Install the enclosed panel mounting bracket (MS-DP-1) as
shown in the figure below.
The tightening torque should be 0.15 Nm or less. Further,
tighten both the right and the left screw gradually and
equally, so that the panel mounting bracket does not tilt.
