1. What are the common materials for circular connector housings?
Common shell materials include metal (such as aluminum, stainless steel) and plastic. Metal casings typically have better shielding and corrosion resistance, while plastic casings are lightweight and suitable for applications that do not require shielding.
-
2. 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.
-
3. Does the circular connector housing support waterproof function?
Yes, many circular connector housings have waterproof features, especially IP67 or IP68 rated housings, suitable for use in humid or outdoor environments.
-
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.
