WEIPU Chrome-Plated Zinc Alloy Industrial Connector — Professional Grade
WEIPU’s industrial connector combines robust mechanical design with precision finishes to deliver long-term, field-proven reliability for demanding industrial environments. Engineered and manufactured under WEIPU’s stringent quality system, this product ensures consistent contact integrity, corrosion protection and service life you can depend on.
Engineered for Uncompromising Reliability
Material integrity and protective finish
The connector body uses high-quality base alloys and a protective chrome finish for superior surface hardness and corrosion resistance. Finished with Zinc alloy with chrome plating, the surface minimizes fretting, resists environmental attack and preserves mechanical tolerances across repeated mating cycles—translating to predictable, low-maintenance operation in outdoor, marine and industrial settings.
Precision electromechanical performance
Contacts and housings are manufactured within tight tolerances to guarantee repeatable electrical performance and low contact resistance under load. WEIPU’s vertical integration and in-house testing ensure every batch meets agreed insertion/withdrawal forces and contact durability requirements before shipment.
Professional-Grade Performance
Designed to relevant standards and certifications
WEIPU has been a leading voice in connector standards since 1996 and is a principal drafter of the GB/T 11918-2014 national standard. Our factory operates under IRIS (Rail Transit) and IATF 16949 (Automotive) frameworks, providing you with traceability, process control and quality systems trusted across transportation, energy and industrial sectors.
Built for harsh environments and mission-critical systems
From IP69K-rated solutions to high-current products up to 800A and medical-grade components capable of 134°C autoclaving, WEIPU delivers connectors validated for the extremes.

FAQ
Are the SP Series compatible with other brands' industrial connectors?
The SP Series follows standard industrial interface specifications; please provide the specific model of the mating connector for compatibility verification.
What types of connectors are compatible with Weipu Precast Cable Assembly?
Our Precast Cable Assembly is pre-assembled with Weipu original connectors, covering SF series, SP series, SY series connectors and other mainstream models. We also provide customized precast solutions according to customer-specified connector models to meet personalized needs.
Is it necessary to choose the EMC shielding function?
It depends on the use scenario. If the connector is used in a complex electromagnetic environment (such as near high-power electrical equipment, frequency converters, etc.), it is recommended to choose the EMC shielding function, which can effectively reduce electromagnetic interference and ensure stable signal transmission; if it is used in a simple electromagnetic environment, the standard version without shielding can meet the requirements.
Which thread standard should I choose for my equipment?
It is recommended to confirm the equipment's origin and interface specification first. Metric thread is suitable for European equipment, PG thread for German standard motors/control cabinets, and NPT thread for American standard high-pressure equipment. Our technical team can also provide matching suggestions based on your equipment parameters.
