High Current Circular Connectors by WEIPU

Overview

Overview: WEIPU's high current circular connectors are engineered for demanding environments where power density, safety and long-term reliability matter. Founded in 1996, WEIPU combines nearly 30 years of expertise with a vertically integrated production system across an 80,000 m² facility, offering more than 70,000 specifications to serve global markets.

Technical Performance

Technical Performance: Our high current circular connectors support ratings up to 800A and are offered with IP69K protection for washdown and harsh environments. Designed for precision contact geometry, thermal management and secure locking mechanisms, these connectors minimize voltage drop and maximize service life even under repeated mating cycles and high-temperature conditions, including medical-grade solutions resistant to 134°C autoclaving.

Applications & Industries

Applications & Industries: WEIPU high current circular connectors are widely used in renewable energy (inverters, energy storage), industrial automation and smart manufacturing, rail transit, automotive and medical devices where mission-critical connectivity is essential. Their robust construction and high-current capability make them ideal for converters, battery systems and heavy-duty power distribution modules.

Manufacturing, Quality & Certification

Manufacturing, Quality & Certification: As a principal drafter of the GB/T 11918-2014 national standard, WEIPU adheres to stringent quality controls. Our benchmarks include elite IRIS (Rail Transit) and IATF 16949 (Automotive) certifications. Annual capacity exceeds 55 million units, supported by rapid prototyping (7–15 days) and OEM/ODM development to accelerate time to market.

FAQ:

Can the SF Series maintain IP67 protection performance after customization?

Yes. All customization services for the SF Series (such as structural adjustment and material replacement) will undergo strict waterproof and dustproof performance testing. We will ensure that the modified product still meets the IP67 protection standard, while maintaining its original insulation performance and coupling reliability. You can contact our sales team to put forward specific customization requirements.

How long does it take to receive a custom quote?

Standard products: 7 working days; customized products: 10-20 working days (depending on technical complexity).

Are the SY series connectors compatible with the SP series of Weipu?

The interface dimensions and locking mechanisms of the SY series and SP series are different, and they cannot be directly mated. If you need to replace or match, it is recommended to use the same series of products or consult the Weipu technical team for solution design.

What are the differences between engineering plastic and stainless steel housings? How to choose?

Engineering plastic housing has the advantages of light weight and cost-effectiveness, suitable for general industrial and municipal environments; stainless steel housing has better corrosion resistance and impact resistance, suitable for marine salt spray, chemical corrosion and other harsh environments. It is recommended to choose according to the environment and budget.
