FAQ:

What is the difference between version I and II of SA series in cable outer diameter?

Version I and II correspond to different cable outer diameter ranges, which are designed to match cables of various thicknesses for more flexible installation.

How to match WEIPU connectors with the required IP rating?

First, clarify the water exposure conditions of your application (e.g., rain, submersion, high-pressure cleaning) to determine the required IP grade, then select the corresponding WEIPU series (e.g., IP67 for outdoor use, IP69K for heavy industry).

What are the advantages of black nickel-plated zinc alloy shell compared with ordinary zinc alloy shell?

Compared with ordinary zinc alloy shells, black nickel-plated shells have two core advantages: first, the black nickel plating layer has stronger corrosion resistance, which can better adapt to humid, salty, and other corrosive environments; second, the black nickel appearance is more elegant and textured, which is more suitable for the matching needs of high-end industrial equipment. At the same time, the mechanical strength of the zinc alloy base material is retained, ensuring structural stability.

Is the TYPR-231 connector compatible with other models of Weipu waterproof connectors?

The TYPR-231 series has a standard interface size and locking mechanism. Under the premise of consistent rated parameters and pin configuration, it can be compatible with some universal industrial connectors of the same specification. For the best use effect, it is recommended to use Weipu original matching connectors.

Can the WT29 series be used with cables larger than 2.5mm²?

No. The max wire size is 2.5mm²/16AWG. Using larger cables may cause poor connection or terminal damage.
