1. What are the common materials for circular connector housings?
Common shell materials include metal (such as aluminum, stainless steel) and plastic. Metal casings typically have better shielding and corrosion resistance, while plastic casings are lightweight and suitable for applications that do not require shielding.
-
2. What is the protection level of the circular connector housing?
The protection level is usually represented by an IP code, such as IP67. This level indicates the protective ability of the shell against solids (such as dust) and liquids (such as water). High IP rating is suitable for outdoor and harsh environments.
-
3. Does the circular connector housing support waterproof function?
Yes, many circular connector housings have waterproof features, especially IP67 or IP68 rated housings, suitable for use in humid or outdoor environments.
-
4. How does the circular connector housing ensure the mechanical stress release of the cable?
The casing is usually equipped with cable clamps or stress relief devices, which firmly fix the cable to prevent mechanical stress caused by pulling or bending from being transmitted to the electrical connection part of the connector, thereby extending the life of the connector.
