Amphenol Quadrax contacts are a specialized connector solution engineered for demanding applications requiring high-speed data transmission, 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, alongside a rugged outer contact wall for durability. They are primarily utilized in MIL-DTL-38999 Series III connectors and are frequently found in Gigabit Ethernet assemblies, ARINC 600 systems, and rack and panel connectors. The gold-plated crimp termination ensures reliable connectivity, and their compatibility with various cable types and tooling options makes them a versatile choice for engineers and technicians.
