Introduction
Product Overview
Amphenol Aerospace offers a comprehensive range of high-frequency contacts designed for demanding applications in military and commercial aviation, military vehicles, missiles, and C4ISR systems. These contacts, including coaxial, twinax, triax, quadrax, and differential twinax types, are engineered for superior electrical performance, high data transfer rates, and excellent EMI compatibility. They are primarily integrated into MIL-DTL-38999 circular connectors but are also compatible with other Amphenol connector series and transition adapters for PCB integration. The product line emphasizes reliability, high-frequency capability (up to 40 GHz for some coaxial contacts), and robust construction for harsh environments.
