FAQ:

What are the key differences between the WY Series bayonet connectors and traditional threaded connectors?

The WY Series adopts a bayonet coupling design, which enables quick locking and disconnection without tools, greatly improving installation and maintenance efficiency. In contrast, threaded connectors require multiple rotations to lock, which is time-consuming in scenarios requiring frequent mating. In addition, the WY Series maintains the same anti-vibration and connection stability as threaded connectors.

What should I pay attention to when installing the ST Series connectors?

When installing, first ensure that the cable outer diameter matches 5-8mm; second, when soldering, control the soldering temperature and time to avoid damaging the PPS insert due to high temperature; finally, ensure that the threaded coupling is fully tightened to ensure the IP67 waterproof and dustproof performance. It is recommended to follow the official installation manual for operation.

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.

Why does the WAC Series use different shell materials for plug and socket?

The plug (PA66) needs higher wear resistance (frequent plugging), while the socket (PC) needs better insulation performance (fixed installation in equipment). This combination balances durability and electrical safety for audio equipment connections.
