Product Features
- Integrated buckle locking mechanism: clear “click‑in” tactile feedback, strong anti‑pull‑out performance against vibration and mechanical shock
- Polarized housing design, prevents reverse mis‑mating during manual or automatic assembly
- LCP high‑temperature resistant insulator, withstands SMT reflow thermal profile without housing melting or deformation
- Phosphor‑bronze dual‑beam contact structure, stable contact resistance over multiple mating cycles
- Horizontal right‑angle SMT footprint, 1:1 compatible with 502386 series footprint, zero change for existing PCB
- Tape‑on‑reel packing for pick‑and‑place; multiple pin‑length & plating selections for diverse project requirements
- RoHS & REACH compliant, UL 94V‑0 flame retardant rating
Product Advantages
- Drop‑in interchangeable: 100% footprint compatible for 502386 series, no PCB redesign, fast BOM substitution for shortage‑relief projects
- Enhanced buckle retention: Optimized latch geometry, better anti‑vibration performance than generic friction‑lock versions; suitable for moving‑part devices
- Production‑friendly: LCP material handles reflow heat well; tape‑reel packing fits standard SMT pick‑and‑place, low assembly defect rate
- Cost‑effective local alternative: Shorter lead‑time vs imported original parts, flexible MOQ for prototype & mass‑volume orders
- Customizable options: Adjustable pin count, plating (tin/gold flash), custom tape‑reel specification available for special projects
Application
- Consumer electronics: smart home modules, small household appliances, wearable devices
- Display & LCD modules: internal signal interconnection for small‑size panels
- Industrial control: compact sensor modules, small PLC peripheral boards
- Robotics & UAV: internal signal wiring for flight‑control & auxiliary modules
- Medical devices: portable diagnostic equipment internal low‑voltage signal links
- Automotive interior auxiliary modules: non‑safety‑related signal connections
FAQ
1. Q: Do you have a catalogue? Can you send me the catalogue to check all your products?
A: Yes, you can contact us online or send an Email to get the catalogue.
2. Q: I can't find the product in your catalogue, can you make this product for me?
A: Our catalogue shows most of our products, but not all. Just let us know what product you need, and how many you want. If we do not have it, we can also design and make a new mould to produce it. For your reference, making an ordinary mould will take about35-45 days.
3. Q: Can you provide a sample? Are these samples free?
A: Yes, we provide 5-10 pcs of connector free samples for testing. But you have to pay for the shipping cost
4. Q: What about your delivery time?
A: Stock goods are delivered within 1 day; customized goods are delivered within 5-7days
5. Q: How to ship my order?
A: For small packages, send them by Express, such as DHL, FedEx, UPS, TNT, EMS. That's Door-to-Door service. For big packages, we can send them by Air or by sea. We use standard export cartons. We are responsible for any product damage caused during delivery.
6. Q: What kind of payment do you accept? Can I pay RMB?
A: Weaccept T/T(Wire transfer), Western Union, and PayPal. Please make sure that we can receive the same amount as the Invoice. And you can pay in RMB. No problem.
7. Q: How about your company's quality control
A: Strictly obey ISO9001, IQC, OQC, IPQC, QA occupy 10% of our Quality department. All of our products will be tested by CCD.
8. Q: I need your price list of all your products. Do you have a price list?
A: We do not have a price list of all of our products. Because we have so many items, it's impossible to make all of their prices on a list, and the prices are always changing because of the material cost and quantity. And you can give us a list of all of the items you need; we will confirm carefully one by one and give you a specification and price list
9. Q: Can you make customized products and customized packing?
A: Yes. We have made a lot of customized
products for our customers formerly (mainly wire harnesses). About customized packing, there is no problem for we put your logo or other information on the package. Just have to point out that it incurs additional cost.
10. Q: What certificates do you have?
A: CE, CQC, UL, ISO9001, ISO14001, IATF16949, ISO45001, QC080000, etc.
