PY04 Waterproof Circular Connector | Aviation Plug for Drone UAV Flight Control, Power & Signal Transmission

PY04 series are used widely in all kinds of electronic equipment.This connect is small in size and light in weight.The flange are round and square. They are manufactured under strict ISO 9001:2015 quality management system. We operate in a 5-story modern production facility with a total area of 4,810 square meters, equipped with a full set of high-precision automated production equipment to ensure stable mass production and consistent product performance.

Our production lines include more than 120 sets of advanced equipment: CNC lathes, CNC machining centers, forging machines, stamping machines, thread rolling machines, and other automated processing equipment. To guarantee superior quality and dimensional accuracy for every washer hose connector, we also maintain a complete quality inspection laboratory with professional testing devices, including 3D coordinate measuring machines, optical projectors, surface roughness testers, hardness testers, tension testers, and more.

Quality Control

Our professional engineering and QC teams strictly monitor and control every stage of product development, production, processing, and finished product inspection in full compliance with international quality standards. Each washing machine hose connector undergoes multi-point inspection and performance testing to ensure excellent sealing, pressure resistance, durability, and long service life.

We have rich experience in OEM & ODM customization for plumbing fittings and washing machine connectors. Custom orders are highly welcomed. If you have new projects or product development needs, please send us your 2D / 3D drawings (STP, IGS, DWG, DXF). We will provide professional, detailed quotations and solutions for you within 24 hours.

Widely used in industrial drones, agricultural drones, aerial photography drones, surveillance drones, mapping UAVs, RC aircraft, and other unmanned aerial systems. Perfect for flight control systems, power modules, sensors, gimbal cameras, communication equipment, and various airborne electrical connections.

Provide stable and secure electrical connection for drone flight control, power supply, sensors, cameras, and communication modules.

Transmit power and signals simultaneously with low contact resistance and high signal integrity.

PY04 waterproof & dustproof structure protects internal circuits from rain, dust, moisture, and corrosion.

Anti‑vibration & anti‑loosening locking mechanism ensures stable connection during high‑speed flight and violent maneuvers.

Lightweight & compact design reduces payload and maximizes flight time.

Support quick plug‑and‑play for easy maintenance, module replacement, and on‑site repair.

Wide operating temperature range adapts to various extreme outdoor working conditions.

1.Extreme Vibration Resistance

Adopts reinforced aviation locking structure and precision contacts. Effectively prevents loosening, signal interruption, or power failure caused by long‑term high‑frequency motor vibration and violent flight turbulence, ensuring 100% stable connection during the entire flight mission.

2.PY04 Waterproof & Dustproof

Equipped with dual silicone sealing rings, fully protecting internal components from water, dust, sand, and humidity. Suitable for outdoor, rainy, foggy, and high‑altitude environments, no short circuit, no corrosion, no failure.

3.Ultra‑Lightweight & Compact

Made of high‑strength aviation aluminum alloy or engineering plastic, lightweight yet durable. Minimizes takeoff weight to extend drone endurance and improve flight efficiency, ideal for small and medium drones.

4.Superior Electrical Performance

Gold‑plated contacts ensure ultra‑low resistance, high fidelity, and stable transmission. Effectively reduces signal attenuation and transmission delay, supporting long‑distance and high‑speed data transmission for flight control and image transmission.

5.Quick Connect & Easy Maintenance

Tool‑free quick‑lock design allows one‑hand operation for fast assembly and disassembly. Greatly reduces module replacement and maintenance time, improving mission response efficiency.

6.High Durability & Long Service Life

Withstand more than 1000 mating cycles without performance degradation. High resistance to aging, high and low temperatures, ensuring long‑term stable use in continuous operation scenarios.
