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 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.
-
3. How to choose the cable entry for the circular connector housing?
The size of the cable entry for the casing should be selected based on the diameter of the cable used, ensuring that the cable can be tightly clamped after passing through the entry to prevent tension from affecting the internal connection points of the connector.

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.
