Premium Circular Aviation Connectors – Reliable Connectivity for Harsh Industrial & Aerospace Scenarios

Material quality determines the long-term service life of connectors, and we select two mainstream high-performance materials for core structure production to match industrial long-term use demands.

The conductive pins and inner terminals are made of high-purity brass material. Brass features outstanding electrical conductivity, low contact resistance and strong oxidation resistance, ensuring stable power supply and uninterrupted signal transmission during long-term plugging and frequent vibration. Compared with ordinary iron or alloy terminals, brass pins will not easily rust or deform, supporting more than 500 times of stable plugging cycles without attenuation of electrical performance.

Meanwhile, the connector insulation shell and inner isolation parts adopt industrial-grade PVC material. This PVC material has excellent flame retardancy, insulation performance and wear resistance. It can effectively avoid short circuit, electric leakage and signal crosstalk between lines, and resist daily friction, moisture and low-temperature erosion. It works stably in the temperature range of -40℃ to +85℃, adapting to most indoor and outdoor working conditions.

Equipped with classic threaded locking structure, our circular aviation connectors can be tightly locked after simple rotation. It effectively prevents accidental disconnection caused by equipment vibration, shaking and impact, which is perfectly suitable for vibrating equipment such as automated production lines, vehicle equipment and mechanical arms.

With integral sealing design, this connector reaches IP67 protection level. It can block dust, rainwater and humid air from entering the internal conductive structure, and maintain stable working performance in rainy days, workshops with heavy dust and other harsh environments. No extra protective cover is needed for daily outdoor use.

Standard circular aviation size design realizes universal compatibility with most mainstream aviation wiring harnesses on the market. The plug-and-play structure simplifies manual wiring and assembly steps, greatly saving installation and after-sales maintenance time. We provide multiple pin specifications to meet power transmission and signal transmission demands of different equipment.

• Aerospace & Military Supporting Equipment: Signal connection and power supply for aviation portable equipment and detection instruments
• Industrial Automation: Robots, CNC machine tools, automated assembly equipment
• Transportation Industry: Vehicle monitoring equipment, railway on-board electrical devices
• Outdoor Electronic Equipment: Monitoring equipment, new energy equipment, outdoor communication wiring

All our circular aviation connectors comply with RoHS environmental protection standards, meeting export requirements for European, American and other global markets. Every finished product will pass strict electrical testing and plugging durability inspection before delivery, to eliminate defective products fundamentally.

Besides standard models, we also support non-standard customization including pin number adjustment, wire length matching and surface treatment. Whether you need bulk wholesale or customized connector solutions for special equipment, our professional engineering and sales team can provide you with one-stop support quickly.
