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. How to choose a suitable circular connector housing?
When choosing a casing, the following factors need to be considered:
Application environment (indoor, outdoor or industrial environment)
Protection level
Connector type and specifications
Required shielding performance
Materials and corrosion resistance performance -
4. 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.
