BNC connectors are commonly used in applications such as radio frequency connections, instrumentation, and antenna connections, where shielding from electromagnetic interference is important.  While BNC connectors provide a secure connection, they are not inherently waterproof or waterproof.  However, with additional sealing and insulation, BNC connectors can achieve a certain level of waterproofing to meet different needs.


Waterproof rating of BNC connectors
BNC connectors are not inherently waterproof, but some manufacturers offer waterproof versions of BNC connectors.  These connectors are designed to provide safe and reliable connections, even in harsh environments where contact with water is required.


Waterproof BNC connectors are typically rated IP67 or IP68, depending on the level of waterproofing.  These connectors have a sealing mechanism that prevents water from entering the connector and damaging the device.  The sealing mechanism may consist of a rubber or silicone O-ring that creates a tight seal between the connector and the device.


Make BNC Connectors Waterproof
To increase the water resistance of BNC connectors, additional insulation and sealing must be applied.  Some common methods include:


Rubber boots: Flexible rubber boots that cover part of the BNC connector and cable to protect against splashes and sprays.
Plastic Cover: Molded plastic end caps covering the entire BNC connector provide enhanced sealing and insulation for a higher IP rating.
Waterproof compound: Applying a waterproof silicone, epoxy, or polyurethane compound around the interface of BNC connectors and cables will enhance the seal against moisture.
Shrink tubing: Heat shrink tubing is put over BNC connectors and cables and shrinks to create a watertight seal.  A coat of sealant is usually applied underneath the pipe first.
Coaxial Sealant: The area where the BNC connector connects to the cable is coated with a waterproof coaxial sealant.  Once the sealant hardens, it forms a long-lasting waterproof barrier.

In summary, BNC connectors themselves are not waterproof, but waterproof versions of BNC connectors are available.  These connectors are designed to provide safe and reliable connections, even in harsh environments where contact with water is required. A BNC connector's waterproof rating is often expressed as an IP rating, which indicates its level of protection against water and other liquids.  Waterproof BNC connectors are essential in applications where exposure to water is a concern, such as surveillance systems, aviation and telecommunications.

Many users may not understand the difference between 3.5mm/2.92mm/2.4mm/SMA and may encounter this problem. 3.5mm / 2.92mm / 2.4mm connectors can seamlessly connect shape memory alloys. So how should we distinguish these connectors? The following article will introduce you to the knowledge of these four connectors. I hope this knowledge will be helpful to you.


SMA is designed for use with 0.141 semi-rigid coaxial cable and is typically filled with Teflon dielectric. In the military industry they are used as precision connectors for microwave applications. In that case. Since SMA is small in size and can operate at high frequencies. (The frequency range is DC to 18GHz for semi-rigid cables and DC to 12.4GHz for flexible cables.) They quickly became popular. Even later developed millimeter wave connectors (eg: 3.5mm, 2.92mm) took mechanical compatibility into consideration.

The outer diameter of the 3.5mm connector is 3.5mm. The impedance is 50Ω. The binding mechanism is a 1/4-36UNS-2 inch threaded connector. The biggest difference from SMA is that 3.5mm uses air medium. The outer conductor of the 3.5mm connector is thicker than the SMA connector. Mechanical strength 3.5mm connector is better than SMA connector. 3.5mm connectors not only have better electrical performance than SMA connectors, but also have higher mechanical durability and performance repeatability than SMA connectors. Therefore it is suitable for use in the testing industry.


2.92mm The outer diameter of the connector is 2.92mm. The impedance is 50Ω. The binding mechanism is a 1/4-36UNS-2 inch threaded coaxial connector. The structure of the 2.92 connector is similar to the 3.5 connector, but smaller than the 3.5 connector. The frequency of the 2.92 connector is DC~46GHz, has good electrical performance, and is compatible with SMA connectors and 3.5mm connectors, so the 2.92 connector was quickly accepted by manufacturers. And become one of the most widely used millimeter wave connectors in the world.


The outer diameter of the 2.4mm connector is 2.4mm. The impedance is 50Ω. The outer diameter of the 1.85mm connector is 1.85mm. The impedance is 50Ω. They are smaller internally. Working frequency is higher. Nominally rated up to 50GHz to 60GHz, the two connectors are mechanically compatible and can be connected to each other. But please note that they cannot connect 2.92mm, 3.5mm and SMA connectors. If you connect 2.92mm, 3.5mm and SMA connectors, they will be penetrated.

We will systematically answer your questions from two aspects of UL certification: whether the SMA connector must pass UL certification, and what kind of certification the SMA connector has passed. Details are as follows:
1. What is UL certification?


Generally speaking, the higher the certification level, the better the quality of the product and the greater the safety factor. UL, the full name of Underwriter Laboratories Inc., is the most authoritative in the United States and a large non-governmental organization engaged in safety testing and identification in the world. Due to its independence, its certification test results have high objectivity and accuracy.


2. Does the SMA connector have UL certification?


UL certification is non-mandatory, and the inspection standards are mainly in the United States. Due to different national conditions, UL certification is not the only standard for testing SMA connectors. However, MOCO connectors reminds you that if your connector market is mainly in the United States, it is best to learn about UL certification, because UL certification is mandatory in the United States.
