Thank you very much for using SUNX sensors. Please read this Instruction
Manual carefully and thoroughly for the correct and optimum use of this
sensor. Kindly keep this manual in a convenient place for quick reference.

CAUTIONS
DP4 series is designed for use with non-corrosive gas. It cannot be used
for liquid or corrosive gas.
䢇
Use within the rated pressure range.
䢇
Do not apply pressure exceeding the pressure withstandability value. The
diaphragm will get damaged and correct operation shall not be maintained.
䢇
Make sure to carry out the wiring in the power supply off condition.
䢇
Take care that wrong wiring will damage the sensor.
䢇
Verify that the supply voltage variation is within the rating.
䢇
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.
䢇
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.
䢇
Do not use during the initial transient time (3 sec. approx.) after the power
supply is switched on.
䢇
Make sure that stress is not applied directly to the connector cable joint.
䢇
If the used power supply generates a surge, connect a surge absorber to the
power supply to absorb the surge.
䢇
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.
䢇
In order to reduce noise, make the wiring as short as possible.
䢇
Avoid dust, dirt, and steam.
䢇
Take care that the sensor does not come in direct contact with water, oil,
grease, or organic solvents, such as, thinner, etc.
䢇
Do not insert wires, etc., into the pressure port. The diaphragm will get dam-
aged and correct operation shall not be maintained.
䢇
Do not operate the keys with pointed or sharp objects.
v
MOUNTING
䢇
Mount the enclosed panel mounting bracket (MS-DP-1) as shown in the fig-
ure below.
The tightening torque should be 0.15N·m or less. Further, tighten both the
right and the left screw gradually and equally, so that the panel mounting
bracket does not tilt.
Sensor mounting bracket (MS-DP-3) which can be mounted on a horizontal
plane and sensor mounting bracket (MS-DP-4) which can be mounted on a
vertical plane are also available.
c
PIPING
䢇
When connecting a commercial M5 coupling to
the pressure port, hold the flat sides of the pres-
sure port with a 13mm spanner and make sure
that the tightening torque is 1N·m or less.
If excessive tightening torque is applied, the
commercial fitting may break.

䢇
This product is not a safety sensor. Its use is not intended or designed
to protect life and prevent body injury or property damage from dan-
gerous parts of machinery. It is a normal pressure detection sensor.
䢇
In case this sensor is used within Japan, SI unit must be used since
use of pressure units in Japan is restricted to SI units.
䢇
DIN rail mounting bracket (MS-DP-2), which can fit on a 35mm width DIN rail,
is also available.
