JL24-XTKH Series High-Reliability Interconnects | MIL-SPEC Compliant Crown Spring PCB Connectors

The Guanitron JL24 Series is a high-performance PCB circuit connector engineered to meet the rigorous demands of military and aerospace electronics. Referencing both GJB1438A-2006 (Chinese Military Standard) and MIL-C-55302 (US Military Specification), this series is designed for mission-critical board-to-board and wire-to-board applications where signal integrity is non-negotiable.

The JL24 series features advanced Crown Spring (Hyperboloid-style) socket technology with Φ0.6mm gold-plated contacts. This design ensures multi-point contact, low insertion force, and exceptional stability under extreme environmental stress.

Product Specification

As a MIL-SPEC equivalent connector, the JL24 series is the preferred choice for:

    • Defense Electronics: Ruggedized PCB assemblies for tactical communication and radar systems.

    • Aerospace & Aviation: Avionics control systems and satellite instrumentation requiring high vibration resistance.

    • Industrial Automation: High-precision controllers and heavy-duty machinery electronics.

    • Maritime Systems: Salt-and-moisture resistant connections compliant with Q/DJ-020-2020 standards.

Crown Spring Contact Technology: Features Φ0.6mm Crown Spring sockets for superior electrical conductivity and a stable connection that resists transient interruptions.

Military-Grade Standards: Built to satisfy GJB1438A and MIL-C-55302 requirements, ensuring full interchangeability in global defense projects.

Superior Plating: All contacts are Gold-Plated to prevent oxidation and ensure low contact resistance (≤12.5mΩ) over long-term use.

High-Density 2.00mm Pitch: A 2.00mm contact spacing allows for efficient PCB layout design without compromising voltage clearance.

Extreme Environment Resilience: Operates reliably from -65°C to +125°C and sustains high performance in 95% humidity.
