Amphenol Quadrax contacts are designed for high-performance applications requiring high data transfer rates 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 durability. These contacts are typically used in MIL-DTL-38999 Series III connectors and are available in size 8 crimp termination styles. They are ideal for applications demanding reliable and high-speed data transmission.
