The 4.3-10 connectors are gaining popularity in telecommunications due to their excellent performance in high-frequency applications. The Ingress Protection (IP) rating describes the degree of protection a connector offers against dust and water. It is one of the most important factors to consider when choosing connectors for outdoor use. When choosing connectors for outdoor applications, it’s crucial to comprehend the IP rating of a 4.3-10 connector. Read this article completely to understand the IP ratings for Coaxial connectors.

Overview of 4.3-10 Connectors

In response to the need for a more compact, effective replacement for conventional connectors like the 7/16 DIN and N connectors, 4.3-10 connectors were created. The International Electrotechnical Commission (IEC) standardized the 4.3-10 connector system in 2014. Its name is derived from its 4.3mm inner diameter and 10mm coupling nut.

Understanding Ingress Protection (IP) Ratings

A connector’s IP rating describes how well it can protect against the entry of water and dust. It is expressed as two digits, the first digit representing the degree of defense against solids like dust and the second digit representing the degree of defense against liquids like water. The better the level of protection, the higher the number.

IP Ratings of 4.3-10 Connectors

A 4.3-10 connector’s IP rating can change depending on the manufacturer and particular model of the connector. However, most 4.3-10 connectors have an IP67 minimum rating. This indicates that the connector has complete dust protection and can withstand immersion in water for up to 30 minutes at a depth of 1 meter.

Advantages of IP67 Rated 4.3-10 Connectors

For outdoor applications, choosing IP67-rated 4.3-10 connectors over conventional connector types has several advantages:

Protection from Dust

Connectors with an IP67 rating offer complete dust protection, which is crucial in outdoor applications where dust and other particles can harm connectors.

Protection from Water

IP67-rated connectors are perfect for outdoor applications where connectors may be exposed to rain, snow, and other types of water because they can withstand immersion in water for up to 30 minutes at a depth of 1 meter.


Connectors with an IP67 rating are made to withstand challenging environmental conditions, such as exposure to UV radiation and a wide range of temperatures.

Performance Reliability

Connectors with an IP67 rating offer dependable operation in outdoor applications, ensuring that equipment functions properly in all weather conditions.

Applications of IP67 Rated 4.3-10 Connectors

4.3-10 connectors with an IP67 rating are frequently used in outdoor applications, such as:


4.3-10 connectors, including base stations and antennas, are widely used in mobile communication systems.


4.3-10 connectors are frequently used in broadcast systems to transmit top-notch audio and video signals.

Radio Systems

Radio systems like public safety and military radios use 4.3-10 connectors.

Aerospace and Defense

Radar and satellite communication systems are examples of aerospace and defense applications that use 4.3-10 connectors.

Test and Measurement

4.3-10 connectors, including network and spectrum analyzers, are used in test and measurement equipment.


In conclusion, a 4.3-10 connector’s IP rating is important for outdoor applications. Most 4.3-10 connectors have an IP67 rating, which offers total protection from dust and immersion in water for up to 30 minutes at a depth of 1 meter. IP67-rated 4.3-10 connectors have durability and consistent performance benefits compared to conventional connectors. Numerous outdoor applications, such as telecommunication, broadcast, aerospace, and defense, use them extensively. Choosing the appropriate IP rating for 4.3-10 connectors guarantees proper operation, minimizes downtime, and prevents expensive repairs.
