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, ensuring efficient signal transmission. The rugged outer contact provides durability, making them suitable for demanding environments. Available in size 8 crimp termination style, these contacts are a key component in MIL-DTL-38999 connectors, requiring modification to accommodate keyed contacts. They are ideal for Gigabit Ethernet and other high-speed data communication applications.
