The family of HD/DB connectors, also known as D-Sub connectors, is widely used in industrial, electronic, and IT sectors for transmitting serial signals (RS232/RS485), parallel signals, and analog video.

At KM Soltec, you’ll find a wide selection of DB9, DB15, and DB25 adapters and connectors, male/female, straight or angled — ideal for technical installations, repairs, or retrofitting legacy systems.

What Are DB Connectors?

D-Sub connectors – short for D-Subminiature – are standardized to provide a solid and shielded connection between devices.

The DB designation is followed by the number of pins (e.g., DB9 = 9 pins), each serving a specific function depending on the application.

HD/DB Connectors: Types

Here are the various types of HD/DB connectors you’ll find in our catalog.

DB9 Connectors – Serial Interfaces (RS232, RS485)

DB9 male/female connectors are among the most common for serial connections.

Used in industrial systems, POS devices, PLCs, modems, electronic scales, and embedded devices, they’re ideal for low-speed, high-reliability data transmission.

DB15 Connectors – VGA Video

The HD15 version (commonly known as VGA) is still used today to connect analog monitors, projectors, or legacy display systems.

Available in male/female versions, also angled or with mounting screws.

DB25 Connectors – Parallel or Serial Interfaces

DB25 connectors were the standard for parallel ports (printers, scanners) but are still used in specific applications like automation, CNC, testing, and control.

Also available in crossover configurations, gender changers, or with solder terminals.

Where to Use an HD/DB Adapter?

An HD/DB adapter is used for specific applications:

• To connect legacy devices to modern systems
• To replace worn or damaged connectors
• To create custom cables with D-Sub terminations
• In industrial, electronic, or laboratory applications
• For use in embedded systems, automation, or legacy networking
