A waterproof connector is a connector with the ability to work underwater, which can provide normal, safe, and reliable power and signal transmission to electronic components, and can also play a very good waterproof and dustproof effect.
At present, the main evaluation standard for the waterproof performance of connectors is based on the IP waterproof level standard. The waterproof performance mainly depends on the last two digits of the IP, representing dust and waterproof, respectively. The first digit is from 0 to 6, with the highest level being 6. The second digit is from 0 to 8, with the highest level being 8. Therefore, the highest waterproof level of waterproof connectors is IP68.

Waterproof connectors are widely used in various fields, such as LED lighting, urban outdoor lighting engineering, lighthouses, cruise ships, aviation, industrial equipment, cables, sprinklers, and so on.
At present, waterproof connectors are transitioning from standard products to customized products, from traditional single signal transmission to mixed signal transmission (power and signal), and towards modularization, intelligence, and ultra miniaturization. With the miniaturization of electronic products, the requirements for high integration and waterproofing are becoming increasingly high, which has also driven the development of waterproof connector products towards small size, low height, narrow spacing, multifunctional, and long service life. With the increasing demand for waterproofing levels in electronic products, choosing a connector with high waterproofing and reliability is very important for product designers.
