Product overview
A mixed-contact solution built for engineers who need both high-current power and control signal in a single interconnect.
Il 8W8 Combo D-Sub High Power Connector combines 8 standard signal pins with 8 high-power contacts inside one compact D-Sub shell. The 8W8 layout is one of the most widely specified configurations within the broader family of combo D-Sub connectors, giving engineers a space-saving way to consolidate power and control lines that would otherwise need two separate connectors.
Built on a standard DB-size shell footprint, the 8W8 is a drop-in fit for existing panel cutouts and mounting hardware — a straightforward upgrade path for designs that need more power density without a full enclosure redesign. It shows up in industrial automation, power distribution units, motor drives, test equipment, and battery systems wherever a mixed power-and-signal interconnect is required.
As part of our high power D-Sub connector line, the 8W8 is built to tight tolerances with corrosion-resistant plating and precision-machined contacts for stable performance across repeated mating cycles and demanding electrical loads.

Applicazioni
The 8W8 combo connector is used wherever combined power and signal transmission needs to travel through a single interconnect:
- Industrial automation and control panels
- Motor drives and servo systems
- Battery packs and energy storage systems
- Power distribution units (PDUs)
- Test and measurement equipment
- Robotics and automated machinery
- Medical equipment power/signal interfaces
- Renewable energy systems
For outdoor or washdown-rated environments, pair this series with our waterproof D-Sub connector options for added ingress protection. Combo D-Sub layouts are also produced by other major connector manufacturers such as Contatto Phoenix, reflecting how widely this mixed power/signal format is adopted across the industry.

FAQ
What does “8W8” mean in the connector name?
It refers to the contact arrangement: 8 standard signal contacts combined with 8 power (“W”) contacts in a single D-Sub shell.
What is the maximum current rating of the 8W8 combo connector?
Current rating depends on the power contact and plating option selected. Contact our engineering team for the exact rating for your configuration.
Is the 8W8 combo connector waterproof?
Standard versions are not sealed. If IP-rated protection is required, see our waterproof D-Sub connector series or request a sealed variant.
Can the 8W8 connector be mounted using standard D-Sub panel cutouts?
Yes — the 8W8 uses a standard DB shell footprint, compatible with existing D-Sub panel cutouts and mounting hardware.
What termination options are available?
Solder cup, crimp, and PCB-mount terminations are all available depending on your assembly process.
Do you offer custom pin layouts or plating?
Yes — custom configurations, plating finishes, and mixed contact layouts can be produced on request. Contact us with your specifications.
