Smiths Interconnect

Smiths Interconnect, a leading provider of electronic components, subsystems, microwave, optical and radio frequency products, announced today the extension of its high density modular and minimodular connectors ranges with the addition of two new types of data transmission modules.

Smiths Interconnect’s modular and minimodular connectors are easy to assemble, based on the principle of building blocks with a system composed of two elements: modules and frames. Modules of various styles and different contact types are available for different application requirements, combining signal, power, coaxial, pneaumatic and, from now on, data contact technologies into custom arrangements within a single connector frame.

The need for Gigabit data transmission with lower latency is growing in industrial, military and aerospace applications. While all users ask for reliable Ethernet solutions, the applications also require reduced crosstalk for high reliability, operate in harsh environmental conditions with high vibration, mechanical shock and hundred thousand mating cycles. The requirements of these differ in terms of protocols, environmental conditions, certifications and standards.

Standards organisations recognised a need to address the harsh environment that can cause intermittent network. Poor connection can lead to intermittent packet loss: Ethernet connection is sensitive to delays caused by dropped or damaged data frames (packets) as connectors experience flexing from cables, vibration, tempertaure changes leading to contraction and expansion. These problems are intermittent and a result not picked up by continuity test because such a test find open connections and not poor connections. Also, Electromagnetic Interference (EMI) can cause intermittent packet loss: even if one bit of ethernet packet is damaged by the MI, a frame error will be created that causes the entire packet to be rejected by their device. If several packets are damaged in a row, their machine could not function.

Mark Kelleher, Connectors BU Director at Smiths Interconnect, said:  “Our new Cat5e and Cat6A data transmission modules in accordance to IEEE 802.3 combine the proven technical characteristics of the hyperboloid contact with the use of high-quality and compliant insulator material - i.e. the polycarbonate family - to offer industry compliance and high performance”.

The electrical performance of these modules is optimized through low insertion loss, controlled impedance, and high return loss characteristics. These factors contribute to efficient signal transmission with minimal attenuation and reflection, reducing data errors and ensuring high-speed communication. Additionally, the use of high-quality conductors and advanced shielding techniques enhances resistance to electromagnetic interference (EMI), further stabilizing data transmission. By offering a high insulation resistance and low dielectric constant, the material supports consistent signal propagation and prevents unwanted capacitance effects. Moreover, its thermal and mechanical stability ensures long-term reliability, even in demanding environmental conditions.

Compared to existing commercial solutions, Smiths Interconnect Cat5e and Cat6A data transmission modules surpass various limitations, particularly in terms of operating temperature range and durability over multiple mating cycles.

They are designed to withstand higher +125°C and lower temperature -55°C extremes, ensuring reliable performance in harsh environments where standard commercial solutions may fail due to material degradation, signal instability, or mechanical stress. This makes them ideal for applications in aerospace, defence, industrial automation, and other demanding sectors requiring consistent performance under varying environmental conditions.

Additionally, they are engineered for an extended number of mating cycles (up to 100,000), utilizing high-quality contact materials and advanced surface treatments that resist wear, oxidation, and contact degradation. This enhanced durability ensures stable electrical performance over repeated connections and disconnections, reducing maintenance requirements and improving the overall lifespan of the product.

Both new solutions can be used in the standard versions of the modular and minimodular series as well as in those compliant to EN45545 requirements for fire safety, and offer the following distinctive technical features and benefits:

•  Hyperboloid contact technology utilizing high-quality contact materials and advanced surface treatments that resist wear, oxidation, and contact degradation. This enhanced durability ensures stable electrical performance over repeate connections and disconnections.
   
• 100,000 mating cycles as a connector: the extended life of the connector in applications like test & measurement, guarantees reduced cost of maintenance through spares resulting in higher MTBF (meantime before failure).
   
• High-quality insulator material: high-quality insulator material plays a crucial role in maintaining dielectric properties, reducing signal degradation, and ensuring minimal crosstalk between conductors. This results in reliable performance through consistent signal propagation and unwanted capacitance effects. Further, users get long-term reliability through thermal and mechanical stability, even in demanding environmental conditions.
   
• Snap-in contacts: quick installation with simple assembly steps with no special tools for all mounting arrangement e.g. panel, float for blind mating. This results in reduced operator's time to assemble parts and increased productivity.

As a result, Smiths Interconnect Cat5e and Cat6A modules offer significantly greater robustness and longevity compared to other solutions available in the marketplace, providing a reliable, cost-effective, and future-proof data transmission solution.

Finally in parallel with the introduction of the new Cat5e and Cat6A modules, Smiths Interconnect proudly launches the new online configurator for the fully integrated modular L series.

Thanks to the advanced configuration system, the user can select and customize the connector to meet the exact requirements with off-the-shelf components and shortened lead times. The frames range from a basic frame with just 2 side rails and 2 end caps, to more complex versions with jackscrews, back shells, and cable clamps. It comes with 12 frame types (each of these with lengths up to 30 units), 37 module types split into 5 contact types (signal, power, coaxial, data and pneumatic contacts) for a total of 231 module variations (considering male/female and gold plating thickness) giving the possibility to have an infinite number of combinations.

The configurator allows to download 3D and 2D drawings of the product in different file formats and a datasheet for each product that includes the most important technical characteristics in a 2-page document.
