High Power and High Voltage Connectors and Contacts
High Power and High Voltage Connectors have been a part of Amphenol Aerospace’s legacy since World War II. While we still supply decades-old power connectors for military applications, we’re now providing new connectors, such as High Power 38999, High Voltage 38999, HVDC, and custom busbars to meet the latest power needs for electric and hybrid-electric military vehicles, and all-electric urban air mobility and commercial aircraft.
Voltarius is a high-power interconnect system optimized for high voltage applications, with performance up to 1000Vdc and 450A along with essential safety features.
The High Voltage 38999 Series was developed as a solution for all-electric power requirements on commercial aircraft and urban air mobility vehicles, or eVTOLs.
High power contact options for mil-spec type connectors to increase ampacity by up to 50%.
High Power Connectors
Amphenol high power connectors lead the way with modern high-powered electric-driven technology in a world that’s trending toward more electric power. As the world pivots toward the electrification of everything, global industries require connectors that can reliably and safely facilitate high currents and high voltages to power today's and tomorrow’s cutting-edge technologies such as electric military ground combat vehicles and electric vertical take-off and landing (eVTOL) aircraft.

A hybrid of the High Power Matrix 5015 series and D38999 military connector, Amphenol's High Power Matrix 38999 connector uses mil-spec qualified inserts from the Matrix 5015 and combines them with the mechanical interface of the D38999 to bring you the best of both worlds.
An expansion of the GT-5015 series, offering a rugged environment connector in new finishes such as Durmalon and Black Zinc Nickel for military applications.
Amphenol Class L 22992 high-power, heavy duty electrical connectors are designed for high-current electrical loads and are the largest cylindrical Amphenol power connectors available. Class L heavy duty connectors are ruggedized and designed for high power military and industrial applications that need maximum reliability.
QWLD Series heavy duty electrical connectors provide reliable power and control functions in hostile environments where ordinary connectors cannot survive.
Designed for demanding use, Amphenol QWL cylindrical power connectors are compact and ruggedized for a variety of land and sea functions.
High Power Contacts
Amphenol Aerospace's development of High Power Contacts is the foundation of our new High Power Products. The High Power Contacts allow for greater current carrying capacity, or amperage, and are able to withstand higher temperatures in the same sizes as current Mil-Spec style pin and socket contacts.Our Temper Grip Contacts which utilize a stainless steel napkin ring to prevent the beryllium copper tines from “relaxing” at higher temperatures and maintaining a greater area of true contact in all situations to decrease resistance, are rated for 220 amps and 200°C+ for Size 0 contacts. Our RADSOK Socket Contacts utilize a stamped and formed flat grid, uniquely twisted into a hyperbolic geometry to provide robust, high-density contact, are rated 250°C for Size 0 contacts.
Temper-Grip socket contact series is a high-current technology designed for use in high temperature applications, and available with most Amphenol connectors.
RADSOK® technology is based upon a stamped and formed flat grid, uniquely twisted into a hyperbolic geometry to provide robust, high-density contact to the mating pin contact.
Push the current carrying capability past the limits of a Mil-Spec contact, or simply improve the efficiency of your system while reducing the heat dissipated into your platform.
Amphenol has increased its power options for D38999, and a contact system for every application. Featuring Temper-Grip, RADSOK®, HCP and Standard Power contacts.
High Voltage Connectors
The High Voltage 38999 Serie was developed as a solution for all-electric power requirements on commercial aircraft and urban air mobility vehicles, or eVTOLs. They are rated for up to 1200 VAC / 1500 VDC* to remain partial discharge free at 50,000 ft. Standard D38999 Series III shells are used and Dualok plugs are available for increased shock and vibration performance.
HVDC is a low mating force, high mating cycle connector that achieves enhanced performance due to multiple points of contact vs. standard 2 or 4 tine contacts.
Amphenol’s Single Pole Ram-Lock connector is a ruggedized push-pull
connector designed for applications up to 260 degrees Celsius
Next Generation High Power Connectors
These new contact technology developments allow us to greatly improve on mil-spec standard connectors, such as MIL-DTL-38999 Series III, MIL-DTL-5015, and MIL-DTL-22992, to design the next generation of high-power connectors. The Matrix 38999 Series combines the best of 38999 Series III shells and 5015 connector insert assemblies with Temper Grip and RADSOK® socket contacts to provide a much-improved power connector with greater EMI performance in a familiar connector package. The High Power 38999 and High Power 5015 Series also use Temper Grip and RADSOK® contacts to give users up to 1000 amps of current carrying capacity. Our MIL-DTL-22992 Connectors include the standard mil-spec versions, as well as Commercial Class L Connectors and QWLD Connectors. We also have a rectangular, rack and panel-style HVDC Connector for commercial aerospace power needs that can support up to 365 amps.
To provide solutions for all-electric power requirements on commercial aircraft and urban air mobility vehicles such as eVTOL aircraft, Amphenol Aerospace developed the High Voltage 38999 Series. These connectors were developed as future power distribution architecture is moving toward higher voltages than what standard connectors are designed to accommodate. They are rated for up to 1200 VAC/1500 VDC* to remain partial discharge free at 50,000 feet. Standard D38999 Series III shells are used and Dualok plugs are available for increased shock and vibration performance.
