    Product Details

    Features and Advantages
    • 1

      The connector system incorporates two key functional features. First, it includes a polarization or keying device to ensure correct mating orientation, preventing accidental reverse insertion that could damage sensitive circuitry—a critical advantage for protecting electronic modules.

    • 2

      Second, it is equipped with a locking screws device (such as a captive screw or thumbscrew system).

    • 3

      This mechanism provides a secure, mechanically fastened connection that is highly resistant to vibration and accidental disconnection, offering the significant advantage of enhanced reliability in mobile or high-shock environments.

    • 4

      The combination of these features ensures a foolproof and robust power link. The standardized 2.5mm pitch balances good electrical isolation with a compact footprint, suitable for a wide range of power ratings.

    Application

    These connectors are primarily used for internal power distribution within electronic chassis and enclosures. Their typical applications focus on creating reliable, user-serviceable connections for modular components, including:

    ⚡
    Power Supply Units (PSUs)

    Connecting internal AC/DC or DC/DC power modules to the main system backplane or motherboard in computers, servers, and industrial controllers.

    🔧
    Internal System Modules

    Providing power to fan trays, drive bays, amplifier modules, or sensor arrays within a larger electronic system.

    🔬
    Test and Measurement Equipment

    Facilitating safe and secure power connections to internal instrument modules.

    🏭
    Industrial Electronics

    Used in PLCs, motor drives, and other control systems where modular design simplifies maintenance.

    Frequently Asked Questions
    Q What is the purpose of the polarization or keying device in these connectors?
    The polarization or keying device ensures that the connector can only be mated in the correct orientation. This prevents accidental reverse insertion, which could otherwise damage sensitive electronic circuitry and modules.
    Q How does the locking screw mechanism improve connector reliability?
    The locking screw mechanism—such as a captive screw or thumbscrew system—creates a mechanically fastened connection that is highly resistant to vibration and accidental disconnection. This makes it especially valuable in mobile, industrial, or high-shock environments where a loose connection could cause system failure.
    Q Why is a 2.5mm pitch used in this connector system?
    The standardized 2.5mm pitch provides a balanced trade-off between good electrical isolation and a compact physical footprint. This makes it suitable for a wide range of power ratings while keeping the overall connector size manageable within electronic enclosures.
    Q What types of equipment are these connectors typically used in?
    These connectors are commonly used in computers, servers, industrial controllers, test and measurement equipment, PLCs, and motor drives. They are designed for internal power distribution within electronic chassis and enclosures, particularly where modular and user-serviceable designs are required.
    Q Can these connectors be used for connecting fan trays and drive bays?
    Yes. These connectors are well-suited for powering internal system modules such as fan trays, drive bays, amplifier modules, and sensor arrays within larger electronic systems, thanks to their secure locking mechanism and reliable mating orientation.
    Q How do these connectors simplify maintenance in industrial electronics?
    By supporting a modular design approach, these connectors allow individual components—such as power modules, drive units, or control boards—to be easily disconnected and replaced without tools or risk of incorrect reconnection, significantly reducing downtime and simplifying routine maintenance in industrial environments.
