D-sub, D-shaped contacts are one of the most common types of connectors in the contemporary electronics industry. They provide high bandwidth, low crosstalk and low insertion loss performance, while their latching design ensures secure connections. The DM130339 is a prime example of the D-Sub family of connectors, and it offers a multitude of advantages when it comes to applications and working principles. In this article, we will explore these two facets of the DM130339 connector.

Application Field

The DM130339 is a miniature, shielded D-Sub contact that is ideal for high speed data applications with data rates up to 10 Mbps. It is well suited for applications in the networking, industrial control, automotive, aerospace, and defense industries. With a robust design, the DM130339 has a rated current of 3.0A with a temperature range of -40°C to +105°C. Its soldering terminals enable termination for either IDC or Solder applications. Its six-finger contact positions provide reliable and secure connections in compact layouts as well as excellent electrical performance.

The DM130339 is also an ideal choice for high-density applications. Its casing is of a size compliant with EN Spec 609214-04, and it can provide up to 65 positions in a single row configuration and up to a total of over 7000 contacts in both the IDC and Solder versions.

The DM130339 is designed for quick and easy installation. Its latching design allows for secure, non-slip connection, and its gold overlay plating ensures an optimum connection even in tough environments. Its self-held fastening system also helps minimize the need for external mounting support.

Working Principle

The DM130339 operates in the following manner. The contact is composed of three components—the cable, the contact pin, and the shell. When the contact is connected to the cable, the contact pin is sandwiched between the cable and the shell. This seals the connection and prevents any moisture or dust from entering the connection.

The contact pin is designed to ensure a reliable and consistent connection. The contact has a floating tip design that enables it to form a secure connection regardless of any mechanical imperfections between the back-shell and the cable. To maintain this secure connection, the contact uses gold overlay plating to ensure a low contact-resistance and to prevent any corrosion. The contact pin also conforms to the EN 609214-02 specification.

In addition to its electrical performance, the DM130339 also has mechanical characteristics designed to provide maximum protection for the environment. The contact is fully shielded to ensure low EMI/RFI emissions, and it has a polarized shell design to prevent accidental cross-connection. The contact is also halogen-free, UL94-V2 compliant, and RoHS compliant.

In conclusion, the DM130339 is an ideal choice for high-speed data applications with data rates up to 10 Mbps. It combines excellent electrical performance with robust mechanical characteristics and a latching design to ensure secure connections. The contact pin, with its floating tip design and gold overlay plating, provides low contact-resistance and protection from environmental conditions. In addition, the contacts are compliant with RoHS specifications and UL94-V2 compliant.
