FAQ
What is the difference between 304 stainless steel and nickel-plated brass materials?
304 stainless steel has better corrosion resistance, especially suitable for marine salt spray and chemical environments; nickel-plated brass has excellent conductivity and cost-effectiveness, suitable for general industrial environments. Choose according to the corrosion level and budget of the working environment.
Can the WF Series connectors be used in marine salt spray environments?
No. It should be specifically noted that Weipu's WS, WF, and WY series connectors are not suitable for marine salt spray environments. The salt spray in marine environments is highly corrosive, and the material and protection design of this series of products cannot resist such strong corrosive effects. Using them in marine environments will lead to rapid degradation of product performance and even failure.
How to select different locking mechanisms for standard circular connectors?
Prioritize threaded connection for fixed installation scenarios with frequent vibration; choose snap-in connection for scenarios requiring frequent plugging and high assembly efficiency; push-pull connection is more advantageous for operation in narrow spaces or scenarios requiring quick plugging/unplugging.
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.
The WEIPU SA Series Push-Pull Industrial Connector offers robust IP67 waterproof protection with durable anodized aluminum housing. This circular connector ensures secure, reliable connections in harsh environments, making it ideal for demanding industrial applications. Trusted quality by WEIPU.
