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.

At Amphenol Aerospace, we have an extensive history of providing high-voltage and high-power solutions. Our legacy dates back to the Second World War when our Sidney plant produced the Scintilla Magnetos that powered advanced radial aircraft engines with high-voltage electrical energy.

 

Nowadays, we continue to focus on providing interconnect solutions, but with different products and applications, such as our High Power 38999 and High Voltage 38999 connectors, HVDC, custom busbars, and more. We remain dedicated to developing connectivity solutions for electric powertrains that propel evolving technologies like electric and hybrid-electric military vehicles and all-electric urban air mobility aircraft. The electrification of everything is underway, and power and voltage requirements are only going to continue to grow as this technology matures. 

 

As electrified technology continues to scale at a rapid pace, it’s crucial that today’s interconnect solutions are up to the task. At Amphenol Aerospace, we’ve determined more voltage and power is required to support next-generation power requirements.

 

Imagining an Electrified World

The International Energy Agency (IEA) anticipates renewable energy to account for approximately 80 percent of global electricity demand in the coming decade. As renewable energy sources continue to grow and the world shifts toward electrification, military and aerospace technology is no exception. Governments, militaries, and corporations view this technology as a beneficial way to reverse the effects of climate change, as well as a force multiplier and a catalyst for strong economic growth. The market for electric aircraft and electric military vehicles is projected to grow substantially, with estimates reaching approximately $30 billion and $17 billion respectively by 2030, as new innovative technologies such as hybrid-electric tactical vehicles and electric vertical takeoff and landing (eVTOL) aircraft take to the roads and skies.

 

Meanwhile, consumer electric vehicles have begun to take off. Just about 17,000 EVs were on the road globally in 2010. By 2021, there were more than 16 million.

 

It's important that interconnect components keep up with the swift pace of electrified innovations. At Amphenol Aerospace, we believe that more voltage and power is critical to meeting the voltage and power requirements of this evolving technology. Our connectors can reliably and safely facilitate high currents and high voltages, and we're committed to delivering powerful and reliable interconnectivity solutions for electric applications as we move into the transformative decades ahead.
