Numatics DPS280 Series User Manual

Do not use corrosive or flammable gases or liquid with this product.
Please use within the rated pressure range. Do not apply pressure beyond recommended maximum pressure,
permanent damage to the pressure sensor may occur.
Do not drop, hit or allow excessive shock. Even if switch body appears undamaged, internal components may
be broken and can cause malfunction.
Turn power off before connecting wiring. Incorrect wiring or short circuit will damage and / or cause malfunction.
Do not use in environment where steam or oil vapor is present.
This product is not explosion-proof rated. Do not use in atmospheres containing flammable or explosive gases.
Avoid wiring the sensor cable adjacent to or in the same cable tray with power or high voltage lines. Doing so
could cause malfunction due to noise.
This product is not a safety sensor. Its use is not intended to protect life and prevent bodily injury or property
damage from dangerous parts or machinery. It is a normal object detection sensor.
