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 these contacts suitable for demanding environments. They are available in size 8 crimp termination style and may require modification of MIL-DTL-38999 connectors for keyed contacts. These contacts are ideal for Gigabit Ethernet and other high-speed data applications.
