GX16 Aviation Connector 15A 250V Gold-Plated Contacts

SF Series Aviation Connectors Specifications and Performance Data

Why Electrical Performance Matters in Industrial Connectors

When selecting a circular connector for industrial control, automotive electronics, or other high-power systems, the electrical performance of the contact interface directly determines long-term signal integrity and operational reliability. A connector that performs well in initial testing but degrades quickly under load or in harsh environments can lead to costly downtime and system failures. This guide explains the key electrical parameters that separate high-reliability connectors from standard alternatives, helping you make an informed purchasing decision.

Contact Resistance: The Core of Signal Integrity

The contact resistance of a connector is a primary indicator of its ability to transmit power and signals without loss or heat generation. Our GX aviation connectors use gold-plated brass contacts, achieving a contact resistance of ≤3 mΩ. This is significantly lower than the ≥8 mΩ typical of tin-plated or ordinary copper-plated contacts, which are more prone to oxidation and signal degradation over time. Lower contact resistance means less heat generation at the junction, reduced voltage drop, and more stable performance over the connector's service life.

What This Means for Your Application

• Reduced energy loss: Lower resistance minimizes power dissipation, improving overall system efficiency.
• Stable signal transmission: Consistent contact quality prevents intermittent failures and data errors.
• Extended service life: Gold plating resists oxidation better than tin or standard copper, maintaining performance in humid or corrosive environments.

Rated Voltage and Current: Matching the Connector to the Load

Rated at 15A and 250V, our GX series connectors exceed the common 10A/200V specifications found in many competing products. This higher rating makes them suitable for high-power applications where standard connectors would be operating at their limits. When evaluating a connector for your system, always compare the rated values against your actual operating conditions, including inrush currents and continuous load profiles, to ensure an adequate safety margin.

Shielding Effectiveness: Protecting Signal Quality in Noisy Environments

With 98% shielding coverage, these connectors offer superior electromagnetic interference (EMI) resistance. This is particularly important in industrial settings where motors, drives, and other high-power equipment generate significant electromagnetic noise. Effective shielding ensures signal integrity and reliable operation even in complex electromagnetic environments, preventing data corruption and control signal errors that can lead to machine malfunctions.

Evaluating Connector Options for Your Project

When comparing connectors from different suppliers, focus on the verified electrical specifications rather than marketing claims. Consider the following checklist to guide your evaluation:

• What is the maximum continuous current and voltage your application requires?
• What is the acceptable contact resistance for your signal or power circuit?
• Does the operating environment expose the connector to moisture, chemicals, or extreme temperatures?
• Is electromagnetic interference a concern in your installation area?
• What is the expected number of mating cycles over the product's lifetime?

For applications requiring frequent plugging in continuous production lines, you may also want to review recommendations on connector durability and mating cycles.

Next Steps for Your Connector Selection

Once you have defined your electrical, mechanical, and environmental requirements, compare them directly against the datasheet values of candidate connectors.
