GX Series Aviation Connector for High-Low Temperature Test Chambers

WS Series Aviation Connectors Types, Materials, and Specs

Selecting a Wide-Temperature Connector for High-Low Temperature Test Chambers

For scientific research high-low temperature test chambers operating between -50°C and 150°C, the connector must maintain stable electrical performance across the entire thermal cycle. The wide-temperature version of the GX series aviation connectors is designed for this application, covering a temperature range of -55°C to 150°C, which fully encompasses the chamber's operating limits.

Key Performance Specifications

• Temperature Range: -55°C to 150°C, ensuring continuous operation across the full test chamber range without performance degradation.
• Contact Resistance: Less than 3mΩ, providing stable signal integrity for precision measurements.
• Signal Stability: Annual drift of ±0.1%, meeting the accuracy requirements for material performance testing and electronic component reliability assessments.
• Protection Rating: IP67, preventing condensation ingress inside the chamber and reducing the risk of short circuits.

Material and Sealing Design

The GX series wide-temperature connectors use special rubber sealing rings that remain flexible at low temperatures and resist aging at high temperatures. This material selection is critical for maintaining a reliable seal during rapid temperature transitions, which is common in thermal cycling tests.

Application Suitability

These connectors are suitable for scientific research environments where precise data acquisition is required, including:

• Material property characterization under thermal stress
• Electronic component reliability testing
• Long-duration temperature cycling experiments

Installation Considerations

When integrating the connector into a test chamber, verify that the cable assembly and mating interface are rated for the same temperature range. The connector's IP67 rating protects against condensation when the chamber is opened or during humidity testing, but ensure the mating connector is properly locked to maintain the seal.

Selection Checklist

Before specifying a connector for your test chamber, confirm the following parameters with your supplier:

• Continuous operating temperature range versus short-term exposure limits
• Mating cycle rating for frequent chamber access
• Cable gland compatibility with your chamber wall thickness
• Signal type (thermocouple, RTD, or digital) and required shielding
