Amphenol Quadrax contacts are designed for high-performance applications requiring high data transfer rates and low power consumption. These contacts feature four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, along with 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 to accommodate the keyed contacts. These contacts are ideal for Gigabit Ethernet and other high-speed data transmission applications.
