JIANCHA is a direct factory supplier of SF series aviation plugs. We accept bulk purchase and custom production according to your drawings, welcome to send inquiry and place orders! Zhejiang Gao Shi Wei Aviation Connector Co., Ltd. was founded in 1998. We have focused on manufacturing aviation connectors for more than 20 years and specialized in aviation plug products. We own independent production workshops, testing equipment and complete quality inspection systems. Our company has obtained GB/T19001-2016 / ISO9001:2015 certification for quality management system, and all products carry CE marking. Quality inspection reports are attached for every shipment. We reject inferior goods, so buyers can test samples with confidence. Small-batch sampling and tiered pricing for large orders are available, and the quality of samples is consistent with mass production goods.
This SF series circular aviation connector adopts zinc alloy shell, which is impact-resistant, lightweight and durable. It features quick push-pull self-locking connection. Multiple pin options are available: 2/3/4/5/6/7/8/9/12/15 pins, covering mainstream models including SF10, SF12, SF16 and SF20.
The pins are brass with gold plating, delivering high conductivity and extended service life. The insulator is made of PPS thermoplastic, which can withstand high temperature up to 260℃. The shell is treated with brass nickel plating, with an overall IP67 waterproof rating. It can resist extreme temperature, severe vibration, mechanical shock and pressure fluctuation. It is widely used in demanding industrial scenarios such as aerospace, power distribution, marine navigation, high-speed railway, production machinery, ship shipping and power grid systems.
The company currently has 50 employees, including 8 senior technical engineers. The registered capital is 5 million RMB. We focus tightly on this segmented category of aviation plugs. We will not blindly expand irrelevant product lines or overstock inventory. Instead, we keep improving processing technology and batch consistency.
We supply directly from our factory, and the whole production process is fully controllable, from incoming brass and zinc alloy raw materials, CNC machining, electroplating, assembly to final testing. All products go through multiple quality verifications before delivery. We mark all parameters truthfully without exaggerating waterproof performance or plating thickness. This principle brings stable reputation among long-term partners, and many regular buyers keep reordering because of our consistent quality.
For model selection and assembly, this aviation plug can be disassembled easily for convenient operation. It consists of shell, socket, insert core, contacts and other components with solid and reliable structure.
It supports flexible wiring methods: ✅ Soldering type: fits SF6 / SF8 / SF10 / SF12 / SF16 ✅ Crimp type: fits SF16 / SF20 ✅ SF20 also supports screw crimping for Φ2.5mm pins
Harness manufacturers can freely select wiring solutions according to their own production processes, without modifying production lines to match the product.
Core specifications for reference: Insulation resistance: 2000MΩ Mating cycles: up to 500 times Operating temperature: -40℃ ~ +85℃ It works stably in outdoor and workshop environments with drastic temperature difference and strong vibration.
Different series come with different dimensions and current carrying capacity.
SF10: suitable cable diameter 3-6.5mm
SF12: suitable cable diameter 4-8mm
SF16: suitable cable diameter 5-12mm, shell outer diameter approx. 22.5mm
SF20: suitable cable diameter 5-12mm, shell outer diameter approx. 25.5mm
Pin count ranges from 2 pins to 15 pins, and rated current covers 3A to 30A. SF16 series 2-4 pins: rated current up to 15A SF20 series 2-5 pins: rated current up to 30A Contact resistance: as low as 1mΩ for stable electric conduction, suitable for high-current applications.
All these figures are tested by our lab and listed in specification sheets, and customers can verify each item one by one.
Both crimp and soldering versions of our aviation connectors come with standard terminals and sealing rings. The package is moisture-proof and shockproof, so the connectors will not be easily damaged during long-distance transportation.
You can test samples before bulk order. We provide 1-3 pcs samples with fast lead time and quick shipment. Large quantity orders enjoy favorable prices.
We can confirm drawings and 3D specifications for free before order placement to avoid dimension mismatch. Various styles are in stock, including flange type, straight type and locking nut type. You can contact our sales team, and we will recommend the most suitable SF series aviation plug model according to your application.
For projects with higher quality requirements, we can upgrade plating and sealing structure as requested to achieve stable and reliable long-term connection. Batch test reports will be provided together with shipments for your warehouse filing and inspection.
