GX Series Aviation Connectors — Robust Circular Connectors for Panel & Cable Applications

Precise. Practical. Ready for industrial, lighting, audio and control systems.

---

Product Overview

The GX Series aviation connectors (often marketed as GX12, GX16, GX20, GX25, GX30, etc.) are compact, metal circular connectors widely used for panel-mount and cable-to-cable connections. Designed for reliable mechanical contact and simple installation, GX connectors are a cost-effective choice where sturdy metal housings, screw-lock coupling and straightforward wiring are required.

Note: “GX” is a common market name used by multiple manufacturers for this family of circular aviation plugs/sockets. Exact electrical ratings, contact plating, and sealing levels vary by supplier and model — always confirm the vendor datasheet for part-level specifications.

Key Selling Points (at a glance)

• Modular shell sizes — multiple diameters and contact counts to match space and wiring needs.

• Durable metal body — rugged mechanical protection for connectors mounted on panels or equipment.

• Screw-type coupling — secure, vibration-resistant locking suitable for stationary and semi-portable installations.

• Easy installation — cable-to-cable inline, panel-mount receptacles, and simple solder/crimp terminations.

• Cost-effective — ideal where budget, robustness and repeatable performance are priorities.

Typical Models & Form Factors

Common GX family sizes you’ll encounter (model numbering conventions vary by vendor):

• GX12 / GX16 — compact sizes for small sensors, instrumentation or control panels.

• GX20 / GX25 — medium sizes for signal + low-power wiring (audio, control lines).

• GX30 and above — larger shells for multi-pin or higher mechanical-stability requirements.

Each size typically supports multiple pin counts — from 2-pin up to >12 pins depending on shell and insert option.

---

Typical Materials & Construction (industry norms)

• Shell: zinc alloy or die-cast metal with nickel (or similar) plating for corrosion resistance.

• Contacts: brass or phosphor bronze contacts, often plated (tin or gold) depending on supplier options.

• Insulator: molded thermoplastic.

• Coupling: threaded screw collar with nut or clamp for panel mounting.

These are typical materials used across many suppliers. Exact plating, plating thickness and materials depend on the manufacturer and ordered variant — please request datasheets for critical applications.

Sealing & Environmental Notes

• Standard GX aviation connectors are primarily mechanical, not intrinsically hermetic.

• Variants with rubber gaskets or O-rings are available from some suppliers to improve splash resistance and dust protection; check the part’s IP rating before assuming outdoor suitability.

• For outdoor, marine, or fully wet environments, consider sealed connector families (IP67/IP68) or specify gasketed GX variants and cable sealing measures.

---

Electrical & Mechanical Use Cases

• Signal transmission: sensors, control lines, serial interfaces, audio.

• Low-to-medium power: small motors, lighting drivers (verify current rating per pin).

• Panel installations: instrument panels, controllers, power supplies.

• Industrial machines & appliances: reliable fixed connections where frequent hot-plugging is not required.

For any power application, validate the current and voltage rating on the vendor datasheet for the exact GX size and pin configuration.

---

Mounting & Termination Options

• Panel-mount receptacle with mounting nut — common for equipment front/back panels.

• Inline plug/socket for cable-to-cable connections.

• Termination styles: solder-cup, crimp contacts, or PCB-tail variants depending on supplier offerings.

• Accessories: mounting nuts, sealing rings, backshells and strain reliefs.

---

Customization Services (we can provide)

• Custom pinouts & wiring — adapt pin mapping to your schematic or legacy systems.

• Cable selection — jacket materials (PVC/PUR/LSZH), conductor sizes (AWG), shielding options.

• Overmolding & strain relief — add mechanical protection and longer service life.

• Plating upgrades — switch to gold plating for critical low-level signals.

• Panel cutout and harness assembly — deliver ready-to-install cable assemblies and mating panel receptacles.

---

Quality & Testing

Standard QA steps we perform on GX assemblies:

• 100% continuity & pin-to-pin verification

• Insulation resistance and visual inspection

• Mechanical pull-force and strain relief testing on cable terminations

• Batch traceability and optional production test reports

For missions with higher safety or regulatory needs, we can arrange extended tests or third-party verification on request.

How to Specify Your GX Connector Assembly

To get an accurate quote, please provide:

1. GX shell size (e.g., GX16) and male/female preference

2. Pin count and required pinout (a simple wiring table or diagram)

3. Termination type (solder cup / crimp / PCB tail / overmold)

4. Cable spec (length, conductor AWG, shield yes/no, jacket material)

5. Quantity (sample qty and bulk qty) and required delivery lead time

6. Any environmental or certification needs (IP rating, RoHS, flame test, etc.)

We will respond with a technical review, recommended part-level selection, sample plan and a competitive quote.

Final Notes & Recommendation

GX aviation connectors are a pragmatic choice when you need sturdy metal circular connectors that are simple to source, easy to install and economical for large runs. They work best for indoor or protected installations and for applications where reliable threaded locking and metal housings are prioritized.

If you require outdoor-rated or true waterproof performance, please tell us your environmental conditions — we will advise gasketed GX variants or a more suitable sealed connector family.
