1. What is a circular connector housing?
A circular connector housing is a structural component used to protect internal connectors and cables, typically providing mechanical support and environmental sealing to prevent dust, water, chemicals, or physical damage.
-
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. What are the advantages of plastic shells compared to metal shells?
The plastic casing is lightweight, cost-effective, corrosion-resistant, and suitable for low-power applications and indoor environments. The metal casing provides better strength, impact resistance, and shielding performance.
