D-Sub Connectors

D-Sub Miniature Adapters & Couplers

These D-Sub (DB) miniature parts make it easy to extend, convert, or cleanly interface legacy serial and control wiring in the field. This category focuses on DB9 / DB15 / DB25 couplers and modular adapters used for console ports, RS-232/RS-485, automation, telecom, and industrial control.

• Mini couplers (gender changers) — DB9/DB15/DB25 in male/male, female/female, and mixed-gender options
• Hi-density options — compact, high-pin-count variants where applicable
• DB-to-modular conversions — DB to RJ45 / RJ12 adapters for structured cabling and service work
• Field service friendly — ideal for extending existing cables and simplifying bench testing
• Cleaner installs — compact adapters help keep cabling tidy in racks, cabinets, and control enclosures

Use these components to quickly solve “no-fit” or “wrong-end” connector issues, standardize terminations, and keep legacy
interfaces serviceable without rewiring entire harnesses.
