Description
GX16 5-Pin Male & Female Metal Aviator Panel Connector Set
Product Overview
The GX16 5-Pin Aviator Connector Set is a rugged, industrial-grade metal plug and socket pair engineered to establish secure, high-integrity power, grounding, and multi-channel communication links in demanding hardware environments. Widely known as an “aviation connector,” this heavy-duty pair utilizes a standard 16mm panel mounting diameter and features a threaded coupling collar that creates an absolute mechanical lock, preventing accidental disconnects from severe cable tugs, equipment vibration, or physical shock.
This matched set includes a male chassis-mount socket and a female inline cable plug, optimized for multi-wire configurations such as stepper motors with separate grounds, synchronous data communication lines, and multi-rail DC networks. Built with high-conductivity silver-plated brass pins enclosed in a solid, nickel-plated zinc alloy shell, it delivers outstanding grounding, excellent EMI shielding, and long-lasting mechanical durability.
Key Features
-
Threaded Twist-Lock Coupling: Outfitted with a threaded metal locking ring on the female plug that screws securely onto the male panel socket, guaranteeing a vibration-proof connection.
-
Solid 16mm Panel Mount Chassis: The male socket features a flanged, hex-nut surface mount design that locks firmly into standard 16mm ($0.63\text{ inch}$) chassis cutouts without rotating.
-
Premium Zinc Alloy Shell: Constructed from heavy-duty machined zinc alloy with anti-corrosive nickel plating, providing rugged physical protection and excellent electrical shielding against external EMI.
-
Integrated Cable Strain Relief: The female inline plug is equipped with a clamp tail and dual-screw collar at the cable exit point, compressing the wire jacket uniformly to protect internal solder joints from pulling stress.
-
Indexed Internal Alignment: Engineered with a distinct internal keyway slot to ensure the male and female pins align perfectly every time, entirely preventing incorrect orientation or cross-pin shorts.

Application Layouts
The preferred, secure locking interface for multi-channel communication networks, motor systems, and industrial sensory nodes:
-
Industrial Communication Buses: Perfect for routing high-reliability 5-wire serial data protocols including RS-485 interfaces requiring dual differential signals ($A$ and $B$), auxiliary power rails ($VCC$, $GND$), and a dedicated outer shield line.
-
5-Wire Stepper & Servo Configurations: Ideal for managing connections for specialized unipolar or bipolar stepper motor layouts that feature an additional common ground wire or temperature line running back through the panel wall.
-
Multi-Rail DC Power & Signal Hubs: Easily configured to route multiple independent DC references (e.g., $+3.3\text{V}$, $+5\text{V}$, $+12\text{V}$, and dual isolated $GND$ buses) simultaneously into control enclosures.
-
DIY Hardware Prototyping Benches: Providing an easily swappable, wear-resistant umbilical connection node for modular electronic test jigs, complex logic-level distribution units, and external automation rigs.
