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. 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 -
3. What are the standard dimensions for circular connector housings?
The size of the casing usually depends on the type of connector and the application environment, with multiple diameters, lengths, and shapes to choose from. Typical sizes include M12, M16, M23, and so on.
