Amphenol's 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. Typically used in MIL-DTL-38999 Series III connectors, Quadrax contacts are available in size 8 crimp termination styles and offer a bandwidth of up to 3 Gigahertz and data rates exceeding 3 Gbits/sec. They are ideal for Gigabit Ethernet and other high-speed data transmission applications.
