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 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.
-
3. How to maintain the circular connector housing?
Regularly inspect the surface of the casing for wear or corrosion, ensuring that the seals are intact and kept clean. If necessary, aging or damaged casings and seals should be replaced in a timely manner.
-
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.
