Amphenol Quadrax Contacts are designed for high-performance applications requiring high data transfer rates and low power consumption. The unique design incorporates four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, ensuring efficient signal transmission. The rugged outer contact provides durability, making them suitable for demanding environments. These contacts are typically used in MIL-DTL-38999 connectors and may require modification for keyed contact applications. They are ideal for Gigabit Ethernet and other high-speed data communication systems.
