Amphenol Aerospace's Quadrax contacts are designed for high-performance applications requiring high data transfer rates and low power consumption. These contacts feature a unique design with four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, and a rugged outer contact for enhanced durability. They are available in size 8 crimp termination style and are often used in MIL-DTL-38999 connectors, requiring modification for keyed contacts. Suitable for Gigabit Ethernet and other high-speed data transmission applications, these contacts provide excellent EMI compatibility and reliable performance.
