    Product Details

    Features and Advantages

    • 1

      A core feature of this series is its high-density contact arrangement, available in two standard grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm.

    • 2

      This configuration allows for a significantly high number of signal and power contacts within a compact footprint, directly supporting system miniaturization.

    • 3

      The connectors utilize wire twisting pin (twisted-pin) contacts, a design that provides multiple, redundant points of electrical contact.

    • 4

      This yields key advantages: superior electrical conductivity with low and stable contact resistance, excellent resilience against vibration and shock, and enhanced durability over numerous mating cycles.

    • 5

      The series offers versatility in construction with both metal and plastic shell options.

    • 6

      Metal shells provide robust EMI shielding and maximum mechanical strength, while plastic shells offer a lighter-weight alternative for weight-sensitive applications.

    • 7

      This flexibility allows designers to optimize the connector for specific performance, weight, and cost targets without sacrificing the inherent reliability mandated by the GJB2446A standard.

    Application

    These connectors are widely used for electrical circuit connections in military electronic equipment. Their primary application is in systems where small installation space and light weight are non-negotiable design drivers.

    Portable Communication & Reconnaissance

    Man-pack radios, handheld terminals, and surveillance devices.

    Avionics & UAV Systems

    Onboard mission computers, flight control systems, and sensor pods in aircraft and unmanned aerial vehicles.

    Guided Munitions & Weapon Systems

    Electronics within missiles, smart ordnance, and targeting modules.

    Vehicle Electronics

    Dense electronic suites in armored vehicles, command posts, and other mobile platforms.

    Frequently Asked Questions

    Q What grid pitch options are available for this connector series?
    This series offers two standard high-density grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm. These pitches enable a high concentration of contacts within a compact footprint, making them ideal for space-constrained military electronic assemblies.
    Q What are the advantages of wire twisting pin (twisted-pin) contacts?
    Twisted-pin contacts provide multiple redundant points of electrical contact per pin. This results in low and stable contact resistance, superior vibration and shock resistance, and extended durability across many mating and unmating cycles — all critical requirements for military-grade connectors.
    Q When should I choose a metal shell over a plastic shell?
    Metal shells are recommended when robust EMI/RFI shielding and maximum mechanical protection are required, such as in avionics or weapon systems. Plastic shells are preferred in weight-sensitive applications — such as portable communication devices or UAVs — where reducing overall system mass is a priority.
    Q What military standard governs this connector series?
    This connector series complies with the GJB2446A standard, which is the Chinese military standard for high-density rectangular electrical connectors. Compliance ensures the connectors meet rigorous requirements for reliability, environmental resistance, and electrical performance in defense applications.
    Q Are these connectors suitable for use in UAVs and guided munitions?
    Yes. The combination of high-density contact arrangements, lightweight construction options, and robust vibration/shock resistance makes these connectors well-suited for UAV onboard systems, flight control electronics, guided munition assemblies, and targeting modules where size, weight, and reliability are all critical.
    Q Can these connectors be used in both fixed and mobile military platforms?
    Absolutely. This series is designed for versatile deployment across a wide range of military platforms, including armored vehicles, mobile command posts, aircraft, and man-portable equipment. The availability of metal and plastic shell variants allows system designers to tailor the connector to the specific mechanical and environmental demands of each platform.
