How do circular connectors work?

Circular connectors transmit signals, data, or power between devices through multiple conductive contact pins arranged in a circular pattern. They ensure reliable connection through locking structures (thread, bayonet, push-pull) and environmental sealing to resist dust, water, and vibration.

Do you support OEM/ODM customization?

Yes. We offer complete OEM/ODM customization, including:Pin configuration,Cable length & material (PVC/PUR/Shielded),Shell material (metal/plastic),Waterproof rating (IP67/IP68),Shielding & EMC requirements,Special structure design according to customer applications.

What certifications do your products have?

CE / RoHS,IP67 / IP68 Waterproof test,EMC shielding test,ISO 9001 factory system certified.

AI-Powered supplier vetting

SummaryThe supplier operates in electronic component development and sales, with import/export authorization and 16 years of export experience. It offers broad customization and OEM services for well-known brands, maintains inventory capability, and reports quality assurance, two production lines, and lead times within 15 workdays in both peak and off-peak seasons. However, no management-system certification, written complaint-handling or corrective-action procedures, overseas agents, overseas warehouses, overseas showrooms, or offline trade-show participation are reported. Financial credibility cannot be reliably established because the supplied financial records show zero values for revenue, costs, profit, margins, and current ratios. Innovation resources appear limited, with one R&D engineer and no available SDK.

CertificationsThe supplier reports no certification for management systems and no approved supplier list. Although quality assurance is stated to exist, the absence of reported management-system certification means certification holding is not demonstrated.

After-Sales capabilityThe supplier has inventory capability and lists training among its overseas service offerings, but reports no overseas warehouse, showroom, agent, or branch. It also has no written complaint-handling, corrective/preventive-action, or service-capability assessment procedures, limiting evidence of a structured after-sales system.

R&D capabilityThe supplier reports one R&D engineer and no available SDK. It does provide technical development services, but the limited stated R&D staffing and lack of SDK evidence do not demonstrate strong innovation capability.

Production capacityThe supplier operates two production lines, has inventory capability, reports quality assurance, and states peak- and off-season lead times within 15 workdays. However, it has no valid manufacturing-capacity contract with related subcontractors and no written service-capability assessment procedures, so production capacity is supported but incompletely documented.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports OEM service for well-known brands, providing direct evidence of broad customization capability.
