Amphenol's Quadrax contacts are designed for high-performance applications requiring high data transfer rates, low power consumption, and excellent EMI compatibility. The design incorporates four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, along with a rugged outer contact for enhanced durability. These contacts are typically used in MIL-DTL-38999 connectors and require modification to accommodate keyed contacts. They are available in size 8 crimp termination style and offer a bandwidth of up to 3 Gigahertz and data rates exceeding 3 Gbits/sec. Suitable for Gigabit Ethernet and other high-speed data transmission applications.
