Design & Finish: Precision Chrome-Plated Zinc Alloy
Our zinc die-cast housings are treated with chrome plating to enhance surface hardness, oxidation resistance and visual uniformity. The chrome-plated zinc alloy finish reduces wear on mating faces, resists environmental contamination and maintains electrical contact integrity where metallic housings are required. Available in multiple form factors—circular, rectangular and heavy-duty shells—these components offer modularity for bespoke OEM designs.
Performance & Environmental Protection
Zinc alloy with chrome plating is well-suited for enclosures where a durable metal surface is necessary without adding excessive weight. When combined with WEIPU’s sealing systems, these connectors achieve high ingress protection ratings for wash-down and outdoor applications. Our finishes are selected to perform under thermal cycling and common industrial stressors, ensuring dependable service life in tough conditions.

What are the applicable scenarios for the three termination methods of WP20 series?
Solder termination (Φ1mm、Φ2mm、Φ3mm): Suitable for precision components that require stable and fixed connection (e.g., LED display modules, CNC lathe servo components); 2. Screw termination (only Φ3mm): Suitable for scenarios that require frequent disassembly and maintenance (e.g., food packaging machinery control panels); 3. Crimp termination: Suitable for large-scale assembly line production (e.g., batch production of food packaging machinery), with high installation efficiency.
Can WS Series Connectors be used in outdoor low-temperature environments?
Yes. With a temperature adaptation range of -40°C~+85°C, they can operate stably in extreme low-temperature outdoor environments, making them suitable for outdoor industrial facilities in cold regions.
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.
What are the contact options of the TYPR-231 series? How to choose?
The TYPR-231 series is equipped with tin-plated contacts. Tin-plated contacts have good conductivity and high cost-effectiveness, which are fully suitable for general industrial environments with no special corrosion requirements. It is recommenxingded to select according to the actual working environment and budget.
What customization options do you offer for OEM connectors?
A1: We provide design (structure, pinout), branding & marking, electrical/physical parameters, functional (waterproof/locking), and standard compliance (IEC/GB/UL) customization to fit your industry needs.
A2: Lead time ranges from 6 to 12 weeks, depending on customization complexity, order volume, and technical requirements.
A3: Our strict QC system covers raw material inspection, production monitoring, comprehensive performance testing, and final batch inspection to meet industrial standards.
A4: Yes, we develop functional prototypes for your testing and approval to ensure alignment with your requirements before mass production.
A6: Yes, all OEM products comply with international (IEC, UL) and national (GB/T) standards, ensuring safety and reliability in global markets.
A7: Yes, we maintain a large inventory of spare parts for quick delivery, minimizing operational downtime.
