Amphenol Quadrax contacts are designed for high-performance applications requiring high data transfer rates, low power consumption, and excellent EMI compatibility. 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 for keyed contacts. Suitable for Gigabit Ethernet and other high-speed data transmission applications.
