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. 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.
-
3. What are the advantages of circular connector housings in outdoor applications?
The shell provides protection level, weather resistance, and corrosion resistance, ensuring that the connector operates stably for a long time in humid, extreme temperature, and outdoor environments.
-
4. 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.
