Amphenol Quadrax Contacts are engineered for applications demanding high data transfer rates and robust performance, particularly in Gigabit Ethernet assemblies and ARINC 600 systems. These contacts feature four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, providing exceptional signal integrity. The rugged outer contact enhances durability and reliability. They are gold-plated over nickel for optimal conductivity and are crimp termination style, making them ideal for use in MIL-DTL-38999 Series III connectors. Modification of the connector is required to accommodate the keyed contacts.
