Contacts
High speed contacts
<p>The manufacturer is identified on the contact using a “MINT” mark. This mark is recorded in a certification organization and is unique per manufacturer. For Amphenol Socapex, the mint mark is ||.</p>
<p>Our <a href="/products/contacts/signal-contacts/en3155-signal-contacts" target="_blank">EN3155 contacts</a> are all manufactured in Thyez, France in our dedicated Contacts workshop.<o:p></o:p></p>
<p>Yes there is two lengths for socket contacts because of the connector cavities:</p>
<ul>
<li>M39029/57 and EN3155-003 for MIL-DTL-38999 series II, EN4165 and 2M</li>
<li>M39029/56 and EN3155-009 for MIL-DTL-38999 series I and III and EN364.</li>
<li><a href="/faq?facets_query" target="_blank">What is the meaning of the color bands on standardized contacts ?</a></li>
<li>The color bands are marked on the contact to permit the identification of them.<br>For AS39029 contacts, there are 3 colors bands called “BIN” code (for Basic Identification Number). Please refer to the below chart to determine the BIN code.</li>

<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;">2 major standards defines the contacts for connectors, AS39029 and EN3155. There are defining dimensions and performances. SAE organization is managing AS39029 (United States) and ASD-STAN is managing EN3155 (Europe).</p>

<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;">Some reduced or enlarged crimping barrel designs are defined in EN3155 standard. For enlarged crimping barrels, there is some limitation on the diameter in order to allow the use of the extraction tool and to release the contact while inserted.<o:p></o:p></p>
<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.<o:p></o:p></p>
<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;"><span style="color:black;">The size of the contact is defined by the connector cavity and a relationship with the cable gauge (or AWG). The cable gauge defines the nominal current that the contact can accept. The contact size is identidied by a number. </span></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.
