1. 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.
-
2. Does the circular connector housing have shielding function?
Some metal casings provide electromagnetic shielding (EMI/RFI) for high-frequency signal transmission applications to prevent electromagnetic interference.
-
3. How to ensure compatibility between the casing and internal connectors?
When selecting a casing, it is necessary to confirm its size, thread specifications, installation method, and compatibility with internal connectors to ensure that the casing can be fully adapted.
-
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.
