Technical Support & Purchasing FAQs
ask us anything
Can you manufacture custom connectors based on our specific engineering drawings?
*Yes. As a direct manufacturer, Yolong Connectors specializes in OEM and ODM services. Our engineering team can work directly from your CAD drawings or technical specs to produce custom interconnect solutions tailored for your exact application and harsh environment requirements.
Can you provide direct cross-references for brands like Harwin, Harting, Amphenol, or Glenair?
*Yes. We specialize in manufacturing high-reliability, pin-to-pin drop-in replacements for major international series. Simply paste your current BOM or competitor part numbers into the contact form, and our engineers will provide the exact Yolong equivalent within 24 hours. Zero PCB redesign required.
How do you ensure the reliability of your connectors in extreme or harsh environments?
*We prioritize performance over aesthetics. Our industrial and mil-spec equivalent connectors undergo rigorous in-house testing, including salt spray, extreme temperature cycling, vibration, and ingress protection (IP) testing, ensuring zero failures in mission-critical applications.
Can I get physical samples for our testing?
*Absolutely. We understand that in mission-critical applications (like UAVs or robotics), data sheets are not enough. We are happy to provide physical samples so your team can validate performance in your own test labs. Request samples via the form.
What is your Minimum Order Quantity (MOQ) for factory-direct purchases?
*We offer flexible MOQs to support both R&D prototyping and large-scale manufacturing. While standard off-the-shelf items have very low MOQs, custom tooling projects will have specific MOQ requirements based on the raw materials and machining involved. Please contact our sales team with your project details.
What quality management certifications does your factory hold?
*Our manufacturing processes strictly adhere to international quality standards. We are ISO 9001 certified, ensuring comprehensive quality control from raw material inspection to final assembly and testing.
What is your standard lead time for bulk orders and custom prototypes?
*Lead times depend on the complexity and volume of the order. Generally, standard industrial connectors have a lead time of 2-4 weeks. For custom prototypes, we leverage our agile manufacturing capabilities in Shenzhen to deliver samples within 7-14 days.
How do you handle international shipping and logistics?
*We manage full-cycle cross-border logistics. Depending on your urgency and budget, we offer air freight (DHL, FedEx, UPS) for fast delivery, and sea or rail freight for cost-effective bulk shipments. We provide all necessary export documentation to ensure smooth customs clearance.
