High Power Interconnect Solutions 

 

Amphenol Aerospace has led the connector industry with military and aerospace power distribution connector solutions for decades. Whether it’s helping to power military ground vehicles, military and commercial aircraft systems, or the latest space launch vehicles, Amphenol Aerospace has been at the forefront of connector innovation and development. As we move beyond the current mil-spec standards to more custom, high-power needs, our connector designs and solutions have continued to evolve as the demand for more power increases.

 

High Voltage and Current Requirements Are Not Going Away

 

In fact, they’re only going to continue growing.

 

As mission requirements become more diverse and demanding, military and aerospace systems are being designed to handle a wider range of tasks. This versatility often results in the integration of additional subsystems and technologies, driving up the complexity and power consumption of systems.

 

Advancements in sensor technologies, data processing needs, electronic warfare integration, communication demands, propulsion electrification, energy efficiency considerations, challenges in miniaturization, and the pursuit of expanded mission capabilities are all factors driving up power consumption. Higher voltages are being employed at greater scale to transmit power over longer distances with minimal loss, with increased current necessary for delivering more power to various components.

 

Connectors that can facilitate power distribution requirements beyond what standard circular power connectors are capable of are essential in new military and aerospace development, especially with the push toward electrification and hybrid-electric platforms.  

 

High Volts, High Amps

 

As electrification technologies continue advancing, high voltage and amp considerations need to be considered. The evolving landscape of hybrid-electric and fully electric applications in commercial and military industries requires tailored voltage and amp specifications for optimal performance.

 

Next-generation electrification applications require interconnect systems with material and design enhancements that allow them to safely accommodate high voltage and high-amp power systems operating at a variety of temperatures and altitudes. Striking this balance is essential for the integration and scalability of future electrification technologies.
