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. What are the installation methods for circular connector housings?
Common installation methods include panel installation, PCB installation, or free hanging. Choosing the appropriate installation method for the casing should consider the overall design requirements of the system.
-
3. How to maintain the circular connector housing?
Regularly inspect the surface of the casing for wear or corrosion, ensuring that the seals are intact and kept clean. If necessary, aging or damaged casings and seals should be replaced in a timely manner.
-
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.
