Tips: Work environment of circular connector
Environmental temperature and work temperature: The metal materials and insulating materials of circular connector determine its environmental temperature or work temperature. High temperature can damage insulating materials and lead to decreased insulation resistance and withstand voltage resistance. High temperature can deprive elasticity of metal elastic contact pairs, and accelerate their oxidization and coating deterioration.
Corrosion environment: In the salt-spray environment, circular connector lack of corrosion resistant metal surface can lead to the rapid deterioration of performance. The connector with silver plating contact pairs is not suitable for the environment with a certain concentration of SO2. In the wet and hot environment, mildew is important problem. In such environments, the circular connector with salt fog and mould resistant performance must be chose. The circular connector with highest level of salt fog resistant performance should be chose in maritime environment.
Circular connector has female plug & male socket, simple and firm locking mechanism, easy to seal, insert and dismantle. Aviation connector has 15/17/19 pin to select.
