Many manufacturers, including those producing industrial circular connectors, recognize the need for IP65 protection to ensure the safety and longevity of their products.

What Are IP65 Ratings?

Defining IP65 for Connectors

IP65 ratings represent a globally recognized standard for safety and protection in electrical connectors. The International Electrotechnical Commission (IEC) established the IP ratings system to classify the degree of protection an enclosure provides against solid objects and liquids. According to IEC standard EN 60529, an IP65 rating means the enclosure offers complete protection against dust ingress and resists water jets from any direction. The first digit, “6,” confirms dust-tight protection, ensuring no harmful deposits enter the connector. The second digit, “5,” indicates resistance to low-pressure water jets, which means the connector can withstand cleaning processes or exposure to rain without compromising safety.

Manufacturers design IP65 connector models to meet these strict requirements. They use specialized seals and robust materials to block dust and prevent water from reaching sensitive electrical contacts. The IP65 protection rating assures users that connectors will maintain reliable performance in harsh environments. This rating has become essential for industries that demand consistent safety, such as manufacturing, outdoor installations, and transportation.

Note: The IEC IP65 water protection test requires water to be projected by a 6.3 mm nozzle at a rate of 12.5 liters per minute and a pressure of 30 kPa from a distance of 3 meters for at least 15 minutes. The enclosure must show no harmful effects, confirming its resistance to water jets.

How IP65 Ratings Ensure Safety and Reliability

IP65 ratings play a critical role in maintaining safety and reliability for connectors used in challenging environments.

The Structure of IP Ratings

The structure of IP ratings follows a clear and logical format. Each rating consists of two digits. The first digit represents dust protection, while the second digit indicates water protection. This approach allows users to quickly assess the suitability of a connector for specific environmental challenges.

The First Digit: Dust Protection

The first digit in the IP code measures the degree of protection against solid particles, including dust. The scale ranges from 0 to 6. A rating of 0 means no protection, while a rating of 6 means complete dust-tightness. The table below summarizes the levels:

First DigitProtection Against Solids
0No protection
1Objects ≥ 50 mm (e.g., hands)
2Objects ≥ 12.5 mm (e.g., fingers)
3Objects ≥ 2.5 mm (e.g., tools)
4Objects ≥ 1 mm (e.g., wires)
5Limited dust ingress permitted
6Complete dust ingress protection

A connector with a first digit of 6 offers the highest level of dust protection. This ensures that no dust can enter the enclosure, which is essential for environments with airborne particles.

The Second Digit: Water Protection

The second digit in the IP code addresses water protection. This digit ranges from 0 to 9K, with each level representing increased resistance to water ingress. The table below outlines the scale:

Second DigitProtection Against Liquids
0No protection
1Vertically falling water drops
2Vertically falling water drops (tilted up to 15°)
3Spraying water up to 60° from vertical
4Splashing water from any direction
5Water jets from any direction
6Powerful water jets
7Temporary immersion up to 1 meter
8Continuous immersion beyond 1 meter
9KHigh-pressure, high-temperature water jets

A second digit of 5, as in IP65, means the connector can withstand water jets from any direction. This level of water protection is vital for outdoor and industrial applications.
