• Pressure status can be checked at a glance from the
digital display and bar display.
• Measurement pressure prevents incorrect outputs due
to momentary pressure changes. (*)
• Perform automatic teaching simply by teaching pressure
values for good and bad products.
• Industry’s smallest models at just 28 × 28 × 29 mm.
* Only in hysteresis mode.

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use this product in atmospheres or environments that exceed
product ratings.
● Installation
Do not use the Sensor in an environment subject to corrosive or
combustible gas.
● Wiring
If no linear output is used, cut the gray lead wire short and apply
insulating tape to the lead wire so that it will not come into contact with
any other terminal.
● Adjustments
• Filter the gas with an appropriate air filter so that the applied gas will
be free of moisture or oil.
• Be sure to use the Sensor under the rated pressure.
• When setting the set pressure of the ON or OFF point of the output
transistor by pressing the mode selection key, use a manometer if
precise pressure settings are required. The Sensor has a display
error of ±3% FS±1 digit at room temperature. Refer to Display
accuracy in Ratings and Specifications.
• Turning ON the power
The Sensor is ready to operate 0.5 s after it is turned ON. When the
load and Sensor are connected to separate power supplies, be
sure to turn ON the Sensor first.
● Others
Make sure the Sensor does not get wet.
● Mounting
• Do not apply a tensile strength in excess of 50 N to the cables or
connectors.
• The pressure port (made of aluminum die-cast) is fixed with tapered
R(PT) 1/8 male screws and M5 female screws. When using tapered
screws, use tapered Rc(PT) 1/8 female screws.
• Wrap the tapered R(PT) 1/8 male screws with sealing tape to
prevent any leakage. Tighten the male screws to a torque of 10 N·m
max.
• Tighten M5 female screws to a torque of 2 N·m max.
• Tighten each male screw by using a 12-mm wrench to hold its
hexagonal head, not its body.
E8F2
Hexagonal head
• When attaching the Mounting Bracket to the Sensor, make sure
that each M3 screw is tightened to a torque of 0.5 N·m max.
