4针航空插头和插座套装

This 4-pin aviation plug & socket set is a rugged circular connector solution for industrial electrical and signal wiring scenarios. It consists of a panel-mount female receptacle and a cable-end male plug, providing a secure, vibration-resistant connection between equipment chassis and external wiring harnesses. It is widely used in industrial automation control cabinets, CNC machine tools, LED display screens, communication base stations, security monitoring systems, medical equipment and automotive electronics.

The connector adopts a classic GX16 (M16) threaded locking structure. After aligning and inserting the plug into the socket, users simply tighten the threaded coupling ring to form a firm mechanical lock. This design effectively prevents loosening and disconnection caused by equipment vibration, mechanical movement and cable pulling, maintaining stable contact performance in long-term industrial operation. The integrated anti-misalignment keyway ensures correct pin orientation during mating, avoiding pin damage caused by incorrect insertion.

Electrically, the 4-core configuration supports flexible wiring schemes such as dual-circuit DC power, single-phase AC power + ground, or power + dual signal lines, adapting to different equipment power supply and control signal requirements. The contact pins are made of high-quality copper alloy with gold or silver plating, offering low contact resistance, excellent conductivity and oxidation resistance. The insulator is made of high-temperature bakelite with good insulation performance and mechanical strength. Rated at 5A per contact and 250V AC, it meets the power and signal transmission needs of most medium and small industrial devices.

Mechanically, the socket features a hexagonal flange panel mount design, requiring a 16mm mounting hole on the equipment panel. It is fixed from the rear with a locking nut, making installation simple and secure without special tools. The plug end is equipped with a cable gland and strain relief structure, which clamps the cable to relieve pulling stress and improve sealing performance at the cable entry. The outer shell is made of zinc alloy with nickel plating, providing good corrosion resistance and durability for long-term use in industrial environments.

When properly mated and installed, the connector achieves IP55 protection level, offering dustproof and splash-proof performance suitable for indoor industrial environments and sheltered outdoor applications. It supports over 500 mating cycles, maintaining stable electrical and mechanical performance throughout its service life.

For bulk OEM orders, we support different size options including GX12, GX16 and GX20, various core counts, different contact plating options, custom cable assemblies and private-label packaging. We can also provide pre-wired connector sets according to customer specifications to reduce on-site assembly time.
