How to choose the right waterproof connector correctly?

I. How to choose the right waterproof connector? Waterproof connector is a connector that can be applied in the environment with water, and the internal electromechanical performance of the connector can be guaranteed under a certain water pressure for normal use. The scope of application is very wide, such as lighting, cruise ships, aviation, industrial equipment, cables, sprinkler fire extinguishers, etc., all need to use waterproof connectors. There is another concept about waterproof connectors is the level of protection. What is the protection class? It is the IP protection level. the IP protection level system was drafted by the IEC International Electrotechnical Commission to categorize electrical appliances according to their dust and moisture resistance characteristics. the IP protection level consists of two numbers. One number indicates the level of protection against dust and intrusion (foreign objects here include tools, and in order to avoid electric shocks, human hands and fingers are not allowed to touch the energized parts of the appliance). The second number indicates how well the appliance is sealed against moisture and water intrusion. The higher the number, the higher the level of protection. The step is to confirm the environment in which it will be used. Consider the location and environment where the waterproof connector needs to be used, the humidity of the air, the temperature, indoor and outdoor dust environments, etc., and what devices it needs to be used to connect. Second, to confirm the electrical requirements. Waterproof connector to meet how much voltage and current, what kind of volume and specifications, service life and so on. All should be considered one by one in place.
