Amphenol Quadrax Contacts are designed for high-performance applications requiring high data transfer rates and low power consumption. The contacts feature four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs, ensuring efficient signal transmission. The rugged outer contact provides durability, making them suitable for demanding environments. These contacts are typically used in MIL-DTL-38999 connectors and require modification to accommodate keyed contacts. They are available in various configurations and cable types to meet diverse application needs.
