We live in an era of rapid technological and industrial development, characterized by improvement in productivity level and growth, as well as demand for higher requirements in terms of stable transmission of cable lines. This is because despite the emphasis on environmental protection, some mechanical forces such as heat, dust, moisture, corrosive fluids, gases and vibrations are present during industrial production. These factors are damaging to cable lines and affect stability. Therefore, it is imperative to use a highly stable cable for transmission, along with connectors. In order to address these problems, we are introducing an RJ45 connector that is resistant to water and dust, and can reach an IP68 rating. This waterproof connector is partially suitable for use as Cat 5e connector. It also has a higher data transmission rate, reaching 100MHZ.
