IP Ratings Explained for Waterproof Connectors
What Does “IP” Mean for ip67 or ip68 connectors?
When you see an ip code like ip67 or ip68 on a waterproof connector, you are looking at a globally recognized system for measuring how well a product resists dust and water. The International Electrotechnical Commission (IEC) created this standard, known as ingress protection ratings, to help you compare products easily. The ip code uses two digits to show the level of protection against solids and liquids. This system gives you a clear way to judge if a connector will survive in your environment.
Note: The ip rating system is not just for waterproof connectors. You will find it on many types of electrical equipment, from outdoor lighting to industrial machinery.
How IP Ratings Define Waterproof and Dustproof Standards
The ip rating tells you exactly how much dust and water a connector can handle. The first digit shows the level of protection against solid objects, such as dust or small particles. The second digit measures protection against liquids, including water. The higher the number, the better the protection. For example, ip67 and ip68 both offer complete dust protection, but they differ in their waterproof capabilities.
Here is a quick reference table to help you understand the meaning of each digit:
| Digit | Protection Against Solids | Protection Against Liquids |
|---|---|---|
| 0 | No protection | No protection |
| 1-5 | Partial protection | Dripping, spraying, splashing water |
| 6 | Dust-tight | – |
| 7 | – | Immersion up to 1 meter for 30 minutes |
| 8 | – | Continuous immersion beyond 1 meter (manufacturer specifies depth and duration) |
| 9K | – | High-pressure, high-temperature water jets |
You should always check the ip rating before choosing a connector. This ensures you get the right level of ingress protection for your application. The ip standard helps you avoid costly mistakes and ensures your equipment stays safe and reliable.
Understanding the First and Second Digits in ip67 and ip68
The two digits in an ip rating each have a specific meaning. The first digit, which is ‘6’ for both ip67 and ip68, means the connector is dust-tight. No dust can enter, so you get complete protection against solids. The second digit is where the difference lies. For ip67, the ‘7’ means the connector can handle immersion in water up to 1 meter for 30 minutes. For ip68, the ‘8’ means the connector can withstand continuous immersion in water beyond 1 meter. The manufacturer will specify the exact depth and duration for ip68 connectors.
Here is a summary table for ip67 and ip68:

FAQ
What does “IP” stand for in waterproof connectors?
“IP” stands for Ingress Protection. You use this rating to measure how well a connector resists dust and water. The two digits after “IP” show the level of protection against solids and liquids.
Can you use IP67 connectors underwater?
You can use IP67 connectors underwater for short periods. They protect against immersion up to 1 meter for 30 minutes. For longer or deeper submersion, you should choose IP68 connectors.
How do IP67 and IP68 differ in dust protection?
Both IP67 and IP68 connectors provide complete dust-tight protection. You get the same level of defense against solid particles with either rating.
When should you choose IP68 over IP67?
You should choose IP68 connectors for applications with continuous or deep water exposure. Marine, underground, and submerged installations require the higher waterproof standard that IP68 offers.
Do IP ratings guarantee protection when connectors are unplugged?
No, IP ratings only apply when connectors are fully mated and sealed. You lose protection if you disconnect or leave ports open. Always use sealing caps for unused ports.
Are IP68 connectors more expensive than IP67?
IP68 connectors usually cost more because they use advanced sealing and materials. You pay for higher waterproof performance and longer lifespan in harsh environments.
How do you maintain waterproof connectors?
You should inspect connectors regularly for cracks, corrosion, or dirt. Clean them gently and follow manufacturer instructions for installation. Proper maintenance extends connector life and ensures reliable protection.
Can you upgrade existing systems to IP67 or IP68 connectors?
You can upgrade by replacing old connectors with IP67 or IP68 models. Choose connectors with proper sealing and corrosion resistance. Follow best practices for installation and testing to ensure waterproof performance.
