Engineered for Uncompromising Reliability
Sealing and Environmental Resistance
Precision-molded housings and multi-stage sealing deliver IP69K protection against high-pressure, high-temperature washdowns and dust ingress. This validated ingress protection prevents corrosion, short circuits and performance drift, reducing field failures and maintenance interventions in harsh outdoor, washdown or marine applications.
Electrical and Mechanical Robustness
Robust contact alloys and interference-resistant terminations provide steady conductivity under vibration, shock and thermal cycling. Designed to meet demanding current and mating-cycle expectations, the connector minimizes contact degradation and maintains low-resistance connections across lifecycle stresses.
Professional-Grade Performance & Compliance
Manufacturing Traceability and Certifications
Founded in 1996, WEIPU is a principal drafter of the GB/T 11918-2014 national standard and a global leader in industrial connectors. Our facility expansion to 80,000 m² and annual capacity of 55 million units ensure supply continuity for large projects. Production follows elite IRIS (Rail Transit) and IATF 16949 (Automotive) processes to reduce vendor risk and support regulated industries.
Vertical Integration and Rapid Response
Independent R&D and vertically integrated manufacturing allow consistent quality control and faster lead times. WEIPU provides OEM/ODM services, prototypes in 7–15 days, and a 24-hour rapid response for technical support—reducing project delays and ensuring timely system commissioning.
Built for Peace of Mind
Application Confidence

FAQ
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.
Why is the M23X Series suitable for high-temperature equipment?
The M23X Series has a wide temperature range of -40°C~+125°C, which can adapt to the high-temperature environment of high-temperature equipment. The selected PA66 insert material also has good high-temperature resistance, which can maintain stable performance without deformation or failure in high-temperature working conditions, ensuring the normal operation of the connection system.
What is the advantage of silver-plated contacts for audio transmission?
Silver plating has lower contact resistance than other platings (e.g., gold plating), which can minimize audio signal loss and distortion, ensuring the high-fidelity transmission of sound quality, which is more suitable for audio signal transmission needs.
What does V-0 flame resistance mean for the WT29 series?
V-0 means the shell self-extinguishes within 10 seconds when ignited (no burning droplets), meeting strict fire safety standards for industrial environments.
