<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;">American Wire Gauge is a standardized wire gauge systems defining the diameters of conductive wires. The AWG tables usually are for a single, solid and round conductor. As for the contact size, the higher the gauge or AWG number is, the smaller the wire diameter is. For example, the AWG 0000 (or 4/0) has a diameter of 11.68mm when AWG 40 has a diameter of 0.09mm.</p><p></p>

Quadrax Contacts description

Quadrax Contacts from Amphenol Socapex are designed to provide high data transfer rates with low power consumption, making them an ideal choice for various applications such as Ethernet, AFDX (Avionics Full Duplex Switched Ethernet), cockpit displays, and in-flight entertainment. These contacts are available in contact size 8 and qualified further to EN3155-074 and 075. They can be used with MIL-DTL-38999, EN3645, EN4165, and ARINC600 connectors, and come in both crimp and PC Tails versions. Modification of cavities size 8 is required to accommodate keyed contacts. Quadrax Contacts have a bandwidth of up to 1.25GHz and can exceed data rates of 2.5Gbps. They have a voltage rating of 500VRms max at sea level and can withstand a dielectric voltage of 1000VAC rms between all inner contacts and 500VAC rms between inner and outer contacts at sea level. It's important to note that for a full duplex Ethernet network, two Quadrax Contacts are needed.
Overall, Quadrax Contacts are an excellent option for applications requiring high-speed data transfer with low power consumption.

What are quadrax cables?
Quadrax from Amphenol Socapex are high-speed connectivity solutions designed for military, aerospace, and industrial applications. Featuring a unique quadrax contact configuration, they enable both data and power transmission while minimizing electromagnetic interference (EMI). These contacts ensure reliable performance in challenging environments, making them essential for mission-critical systems.
