Precautions for prorer use

Wring

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.
Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.

Other precautions

Our products have been developed / produced for industrial use only.
Although the protection degree is specified for the sensor including the cable, the cable end is not waterproof, and is not covered by the protection specified. Hence, make sure that water does not seep in from the cable end.
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.
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.
The usage environment should be within the ranges described in the specifications.
Use sensors within the range shown in the white part of the ambient temperature / humidity graph below and also within the certified ambient temperature and humidity range of each product. When using sensors within the range shown in the diagonal line shaded part of the graph, there is a possibility that condensation may occur depending on changes in the ambient temperature.
Please be careful not to let this happen.
Furthermore, pay attention that freezing does not occur when using below 0 ℃ +32 ℉. Please avoid condensation and freezing when storing the product as well.
