In wet and cold natural environments or in liquids, d-sub dual port connectors wholesale aviation plug sockets often suffer from dripping, spraying or intrusion of liquids, so the introduction of waterproof grades can reasonably prevent these problems. Usually one can use iP coding to represent the waterproof rating of d-sub dual port connectors wholesale, that is, IPx(x is a large number from 0 to 8, the greater the waterproof rating), as follows.

Waterproof rating of d-sub dual port connectors wholesale: when x=0 - water does not require maintenance. When x=1 - prevent water droplets from entering. When x=2 - when the housing of the d-sub dual port connectors wholesale is tilted to a 16 degree Angle, water droplets falling into the housing will not be harmed. When x=3- precipitation from a 65 degree corner on the housing or water spray, the RF connector will not be harmed. When x=4 - liquid from all directions, from all angles on the RF connector housing, no harm. When x=5 - no damage to tap water cleaning.

When x=6 - can prevent the entry of strong water (such as the sea), can be used as a natural environment in the cabin. When x=7 - can be used to avoid short periods of flooding throughout the process. When x=8- is continuously soaked under the necessary working pressure, the whole process of water can be prevented from entering the aviation plug joint.

When purchasing d-sub dual port connectors wholesale aviation plugs and sockets, pay special attention to the following points:

The goods should have "CCEE" security certification, and the manufacturer's business name, full address and telephone number should be on the goods; National standards for rated voltage requirements are divided into 6A, 12A, 18A3 three grades. If there are no other levels, they are non-standard goods.

③ Pay special attention to "matching", select products with rated current and voltage consistent with common residential socket switches. The rated voltage should be in accordance with the order of power plugs, power plugs, portable power sockets, household appliances with large power consumption, and should not be confused. ④ Pay special attention to the power plug. In our country's national industry standards, the power plug is flat, there are two and two power plugs, there is a grounding device. Cylindrical power plugs are obsolete goods, do not buy.
