FAQ:

Can WEIPU heavy-duty connectors add new modules later if needs change?

Yes, the modular design supports on-site addition, replacement, or removal of functional modules without replacing the entire connector, enabling flexible adaptation to dynamic project requirements.

What is the advantage of the lock hook connection of the WK16 Series compared to other coupling methods?

The lock hook connection of the WK16 Series has the advantages of tool-free operation, quick mating and disconnection, and simple operation. It can be completed with one hand, which is more efficient for scenarios requiring frequent disassembly and maintenance. At the same time, the lock hook has a self-locking function, which can ensure stable connection without loosening under vibration conditions.

Can the M23X Series be used in coastal salt spray environments?

The nickel-plated zinc alloy shell of the M23X Series has certain corrosion resistance, but it is not suitable for long-term use in coastal salt spray environments with strong corrosiveness. If it is necessary to use it in such environments, it is recommended to select the customized enhanced corrosion-resistant alloy shell to ensure the service life and performance of the product.

Does WEIPU participate in industry standards?

Yes. WEIPU is a member of the National Electrical Appliances Standardization Technical Committees and participated in drafting the national connector standard GB/T 11918-2014.

What does "omit" mean in the cable outer diameter range of the SF Series models?

"Omit" indicates that the corresponding cable outer diameter type of the model is not provided. Customers can select the available type (Type I or Type II) according to their actual cable diameter needs. For example, the SF6 model only provides Type I (2-3mm) and does not provide Type II (3-4mm).
