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 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.
-
3. 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.
-
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.
