Connectors are classified and compared according to their performance when used in different environments. What can connectors be classified by performance? Connector performance of electrical performance, mechanical performance, environmental performance. Mainly these three, there may be waterproof and not waterproof difference in use, waterproof, outdoor use and chassis internal use classification.
However, different connector categories have different performance. Take the classification of waterproof and non-waterproof groups, the corresponding electrical performance and mechanical performance is the industry standard, but the environmental performance is not the same, waterproof level requirements are higher, high enough to soak the water up to 20 years. So choose a good waterproof connector manufacturer is the reason.
