<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.</p><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> </ul><article class="align-center"><img width="555" height="81" alt="color brands contacts contact" loading="lazy" class="lazyload" data-src="/sites/default/files/styles/optimized/public/media/image/2024-02/contact.png?itok=3TpIC9Hy" /></article><p> </p> <article><img width="315" height="95" alt="contact bin code" loading="lazy" class="lazyload" data-src="/sites/default/files/styles/optimized/public/media/image/2024-02/contact_2.png?itok=my15Filt" /></article><p>BIN CODE = 672</p>
<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.

<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.</p><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.</p><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).

<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;">Our engineering team has designed a dedicated interface to meet 75ohms impedance so even if they are close, our impedance matched contacts are not compatible with standard coaxial contacts (such as M39029/59 /60 etc…)</p>
