You may have already seen the expressions IP67 and IP68 in cell phone specifications. They are codes for water and dust protection levels, and tell you how protected your gadget is from the weather. Find out what the difference is between the highest degrees of IP certification.

Connectors with an IP67 or IP68 certificate are a reality, but many consumers still have questions and uncertainties about water resistance. The IP01, IP11, IP21, IP31 and IP41 protection (i.e. with the digit 1 at the end), for example, have minimal water resistance, while those with IP67 and IP68 withstand up to 30 minutes inside the liquid. Check out how manufacturers avoid entry below


What is IP (Ingress Protection)?

The IP Code serves as a guide for users to know if an electronic device has minimum protections against exposure to dirty or wet environments, in order to allow the device to have a longer lifespan.

The Ingress Protection rating determines how much a given device/component resists external stimuli such as water and dust. In general, the reference code is composed with the letters “IP” followed by two numerals, in which the first determines protection for solids and the second for liquids. For example, one connector with IP68 has level 6 resistance against dust and level 8 resistance against liquid.

The IP scale for solids ranges from 0 – i.e. no type of protection – to 6, where there is a guarantee of complete sealing against dust. In the case of liquids, these values ​​range from 0 to 8. Connectors certified with the maximum level support staying submerged up to 1.5 meters deep for 30 minutes.

Below are all the IP protection degrees against water.

0 - No protection
1 - Protection against vertically falling water drops (humidity)
2 - Protection against falling water drops at an angle of 15 degrees
3 - Protection against falling water drops at an angle of 60 degrees
4 - Protection against water sprayed in any direction
5 - Protection against lighter water jets
6 - Protection against intense sea air, against large accumulation of liquids or against jets
of water with pressure
7 - Protection against temporary immersion of up to 1 meter and for a period of up to 30
8 - Protection against complete submersion, against prolonged immersion in situations under

Is water resistance the same as waterproof?

No. Water resistance means that the device can be exposed to fresh water for a certain period of time without being damaged, but it is not recommended to force it. While waterproof appliances are built to be used in direct contact with water. However, even with waterproof or “waterproof” devices, it is important to read the technical data sheet to be aware of the supported conditions.

Therefore, regardless of the certification awarded, it is necessary to check the restrictions determined by the manufacturer to be sure the product is covered against the action of liquids.

The solderstick waterproof connectors have IP67 protection. With its high protection connected or not connected, this connector is perfect for supplying power to devices in aggressive environments, such as industry, navy, laboratories, cars or any type of apparatus around open air.
The connector provides a strong and reliable connection, but at the same time guarantees a disconnection in case required.

This ensures maximum applied power, IP protection and cable retention. The connector can be temporarily submerged in water.

Unlike a common connector, which will not offer the protection and reliability of a IP protection connector.
