1. What is the protection level of the circular connector housing?
The protection level is usually represented by an IP code, such as IP67. This level indicates the protective ability of the shell against solids (such as dust) and liquids (such as water). High IP rating is suitable for outdoor and harsh environments.
-
2. 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.
-
3. 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.
-
4. Which applications require high shielding performance enclosures?
High shielding performance enclosures are mainly used for applications that prevent electromagnetic interference, such as communication equipment, radar systems, industrial control systems, and medical equipment.
