Browse Deutsch Heavy-Duty Circular Connector Families

The Deutsch HD connector range includes several circular connector families designed for different housing, contact and installation requirements. Use this collection when you want to compare heavy-duty circular options before narrowing the catalogue to a specific series.

HD10 Series connectors use thermoplastic circular housings and are commonly selected for transport, diagnostic and equipment wiring. HD30 Series connectors use rugged metal-shell housings for demanding heavy-duty applications. The wider HD range also includes HDP20 thermoplastic circular connectors and compatible variants such as HDB breakaway plugs.

These families can use different shell sizes, contact arrangements and contact sizes, so the series name alone is not enough to determine compatibility. Once the connector housing is identified, match it with the correct contacts and terminals, seals and accessories and any compatible backshells.

For a technical comparison of the circular families, see HD, HD10 & HD30 Connectors Explained.
