1. Does the circular connector housing have shielding function?
Some metal casings provide electromagnetic shielding (EMI/RFI) for high-frequency signal transmission applications to prevent electromagnetic interference.
-
2. 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.
-
3. 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.
-
4. How does the circular connector housing ensure the mechanical stress release of the cable?
The casing is usually equipped with cable clamps or stress relief devices, which firmly fix the cable to prevent mechanical stress caused by pulling or bending from being transmitted to the electrical connection part of the connector, thereby extending the life of the connector.
