<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> <article class="align-center"> <img width="945" height="914" alt="standars driven contacts contact" loading="lazy" class="lazyload" data-src="/sites/default/files/styles/optimized/public/media/image/2024-02/contacts_3.png?itok=Mcs8PzbW"> </article> <p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;"><o:p></o:p></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).

<p class="MsoNormal" style="line-height:normal;mso-margin-bottom-alt:auto;mso-margin-top-alt:auto;">The 387TV series is a low-profile and small form factor connector so to keep it, optimized <strong>size 8 coaxial contacts</strong> have been designed for it. More info available on <a href="/products/io-connectors/38999-series/387tv-series-size-7-connector" target="_blank">387TV Series.&nbsp;</a><o:p></o:p></p>

<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>

<p>Our range of 75ohms goes from contact size 12 to 6. Amphenol Socapex offers the largest range of coaxial contacts for 75ohms to fit in industrial &amp; military connectors such as MIL-DTL-38999, EN3645, EN4165/SIM, 2M and 387TV series.
