Waterproof connectors are connectors that can be applied to environments with water and can ensure the normal use of internal mechanical and electrical properties under certain water pressure. The application range is very wide, such as in lighting fixtures, cruise ships, aviation, industrial equipment, cables, sprinkler trucks, etcWaterproof connector. Before understanding waterproof connectors, it is also necessary to know a concept called protection level.

Waterproof connector

What is the level of protection? NamelyIP protection level. The IP protection rating system is drafted by the IEC International Electrotechnical Commission, which classifies electrical appliances according to their dust and moisture resistance characteristics. The IP protection level is composed of two numbers. The first number represents the level of dust separation and prevention of foreign objects from entering the electrical appliance (the foreign objects mentioned here include tools, and people's palms, fingers, etc. should not touch the live parts inside the electrical appliance to avoid electric shock). The second number represents the degree of airtightness of the electrical appliance against moisture and water intrusion. The larger the number, the higher the protection level.

So how should we choose the correct waterproof connector?

Firstly, confirm the usage environment. It is necessary to consider the location and environment where waterproof connectors need to be used, the humidity and temperature of the air, the indoor and outdoor dust environment, and what devices need to be used for connection. Secondly, it is necessary to confirm the electrical requirements. What voltage and current should the waterproof connector meet, what kind of volume and specifications, and its service life. We need to consider each one thoroughly. Then there are the factors of price and manufacturer. It is appropriate for everyone to be price sensitive when shopping, but it is also important to balance performance and quality. Choose something like DongshengdaSuch manufacturers have a large number of user inspections and have also passed the testing certificates issued by authoritative institutions, truly achieving the goal of providing professional solutions and convenient one-stop procurement services for the vast number of users.
