At Vetco, we stock an expansive range of D-Sub connectors and accessories — including 9-pin D-Sub connectors, 25-pin D-Sub connectors, D-Sub connector backshells, and D-Sub plug connectors — for all your prototyping, repair, or assembly needs.

Whether you're working with computer interfaces, serial connections, or embedded hardware, our collection includes D-Sub connector types suited for both commercial and hobbyist applications. These rugged connectors offer secure, high-density wiring with straightforward installation and a variety of mounting options.

What Are D-Sub Connectors?

D-Sub connectors - also referred to as D-subminiature connectors, D connectors, or Sub-D connectors - feature a characteristic D-shaped metal shield that ensures proper orientation and minimizes EMI. Available in various pin configurations such as DB9, DB15, DB25, and DB37, they are often used in serial (RS-232), parallel, and VGA connections.

Each D-Sub connector comes in male and female variants. For example, a DB9 female connector pairs with a DB9 male connector in RS-232 communication setups. Our collection also includes D-Sub connector hoods and backshells to protect and organize cabling while enhancing strain relief.

Common D-Sub Connector Variants We Offer

• 9-pin D-Sub connectors (DB9) – Ideal for serial ports and PLC communication.
• 15-pin D-Sub connectors – Common in analog video (VGA) and older joystick ports.
• 25-pin D-Sub connectors (DB25) – Used for parallel ports and signal interfaces.
• 37-pin D-Sub connectors – Great for high-density applications requiring more signal paths.
• D-Sub connector backshells and hoods – Provide strain relief and EMI shielding.
• Panel-mount and right-angle options – For flexible design integration.

All connectors are available in both male and female versions, with multiple D-Sub connector sizes and pin configurations to match your project’s requirements. We also carry D-Sub adapter solutions for converting between pin types and genders, allowing seamless integration with legacy or modern equipment.
