Amphenol's Quadrax Contacts are designed for high-performance applications requiring high data transfer rates, low power consumption, and excellent EMI compatibility. The 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. Available in size 8 crimp termination style, these contacts are ideal for demanding environments and require modification of MIL-DTL-38999 connectors to accommodate keyed contacts. They are commonly used in Gigabit Ethernet assemblies and other high-speed data transmission applications.
