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. How can circular connector housings improve the durability of connectors?
The shell can significantly extend the service life of the connector in harsh environments by providing protective measures such as mechanical strength, dust prevention, and waterproofing.
-
4. What is the temperature range of the circular connector housing?
The operating temperature range of the casing depends on the material used. Metal casings typically operate within the range of -55 ° C to+125 ° C, while plastic casings may be suitable for lower temperature ranges.
