Engineered for Uncompromising Reliability
Ingress and environmental protection
The connector is engineered to prevent moisture and particulate intrusion with an IP69K-rated sealing system. Practically, this means sustained performance after high-pressure washdowns, steam cleaning, and prolonged outdoor exposure—minimizing failure risk and maintenance downtime.
Mechanical endurance and materials
Durable housing materials and precision-molded insulators resist abrasion, vibration, and thermal cycling. Contact metallurgy and plating options are selected to preserve low contact resistance across repeated mating cycles, delivering consistent electrical integrity over the connector’s service life.
Professional-Grade Performance
Certifications and traceability
Manufactured by WEIPU—founded in 1996 and a principal drafter of GB/T 11918-2014—this connector is produced within a vertically integrated facility expanded to 80,000 m² with annual capacity of 55 million units. Production follows IRIS (Rail Transit) and IATF 16949 (Automotive) quality controls, providing customers with traceable, certified components suitable for regulated industries.
Design for mission-critical systems
WEIPU’s independent R&D and extensive specification library (over 70,000 SKUs) enable precise matching of electrical, mechanical, and sealing requirements.

Frequently Asked Questions
Are there hidden fees in the quotation?
No, our quotation includes product cost, customization fee, packaging fee, and basic logistics cost. Additional fees (e.g., customs duties, remote area surcharges) are clearly listed separately.
What precautions should be taken for solder termination of the WD28 series?
When performing solder termination, the following points should be noted: 1. Strip the cable insulation layer according to the specified length to avoid excessive or insufficient stripping affecting the connection effect; 2. Control the soldering temperature and time to prevent high temperature from damaging the PPS insert; 3. After soldering, check whether the connection is firm and whether there is solder residue to avoid short circuits; 4. Use professional soldering tools and solder to ensure the reliability of the soldered joint.
What are the advantages of the push-pull coupling of the SF Series compared to threaded coupling?
The push-pull coupling of the SF Series enables one-handed quick mating and unmating without tools, which is more efficient for scenarios requiring frequent disassembly and maintenance. In contrast, threaded coupling requires multiple rotations to lock, which is time-consuming. Additionally, the push-pull design has a more compact structure, making it suitable for narrow installation spaces.
What is the significance of CQC and CE certifications for TYPE171 series?
CQC certification means the product meets China's national safety standards, and CE certification means it complies with the safety, health, and environmental protection standards of the European Union. The dual certifications ensure that the product can be safely used in both domestic and European markets, enhancing product reliability and market adaptability.
