How Does the D Sub 5W1 Coaxial D Connector Improve Mixed-Signal Integration?

The D Sub 5W1 Coaxial D Connector stands out as a versatile and high-performance solution designed for applications that require a compact yet powerful way to transmit mixed signals—including signal, power, coaxial, and even high-voltage contacts—within a single connector body. This hybrid connector is built to meet the needs of various configurations such as board-to-board, cable-to-cable, or panel-to-cable systems, making it highly adaptable for complex system designs. Whether you're designing for telecom, aerospace, industrial automation, or military electronics, the D Sub 5W1 offers unmatched flexibility and reliability.

Constructed with a high-grade insulator made of PBT reinforced with 30% glass fiber (UL94V-0 rated), the connector ensures strong flame resistance and structural integrity under mechanical and thermal stress. The insulator is available in customizable black or blue colors to suit different application preferences. Inside, the contacts are made from durable copper alloy and plated with 1U" to 30U" of gold, ensuring superior conductivity and long-term resistance to corrosion and wear.

The shell is made from nickel or tin-plated steel (SPCC-SD), providing additional protection against environmental and mechanical damage. Electrically, the connector performs exceptionally well: it supports a dielectric rating of 300V AC and has a dielectric withstanding voltage of 1000V AC RMS for 1 minute, ensuring high-voltage isolation capabilities. The contact resistance is a low 2.7mΩ max, and the insulation resistance is at least 2000MΩ at 500V DC, guaranteeing stable signal performance and electrical safety.

For high-frequency coaxial lines, the connector supports 50 or 75 ohm impedance, which makes it suitable for RF transmission and other high-speed applications. Mechanical characteristics are equally robust, with insertion forces up to 12 N per pin and extraction forces as low as 0.3 N, depending on pin diameter. Rated for at least 500 mating cycles, the D Sub 5W1 is built for endurance. It also performs reliably across a wide operating temperature range from -55°C to 125°C, making it a dependable choice for both indoor and outdoor applications.

With optional features like blind mating and sequential mating, the D Sub 5W1 Coaxial D Connector from SIGNALORIGIN® enhances installation convenience and ensures accurate electrical engagement, especially in high-density environments. For engineers and system designers looking to integrate multiple signal types into a single, compact interface, this connector offers a durable, flexible, and technically advanced solution.
