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 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. 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.
-
4. 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.
