Today, the demand for capacity and speed of data transmission through electronic devices has increased globally. For harsh environments, such as avionics and defense, key issues related to high temperatures, vibration, and shock must be considered to maximize efficiency. In space, requirements are even more critical, as the electronics payload must also resist radiation, atomic oxygen, and outgassing.

High speed is a factor that electrical engineers constantly tackle, particularly in extreme situations. At the same time, the risk of signal loss increases as the need for high-speed connectivity surges. The higher the frequency of the signal, the more difficult it is for the recipient to understand the sender. Defending against signal loss must be at the forefront of high-speed design, engineers ensure signal integrity while achieving high speed.

How to minimize signal loss within the transmission path to achieve high speed? There are some methods to control it, most equipment uses a material with high conductivity to improve the high-speed signal. But for connectors, the method is not such useful, to choose a connector in the first instance is very important.

When dealing with high-speed environments it’s tempting to simply pick a connector with a metallic housing, such as aluminum alloy or stainless steel, because these metals typically have the capacity of EMC shielding. On the other hand, the factors such as the diameter of contact, the distance between contacts, and type of materials for all components should be considered in the internal of the connector.

Micro-D High-Speed configurations include wired assemblies and straight or 90° PCB-mount connectors. Insert arrangements feature Twist Pin contacts. Sunkye's Micro D connectors are designed for applications that require stability in extreme environments. Sunkye's connectors are rugged, high-performance, Micro D densely compacted 1.27 mm pitch interconnects. Sunkye connector series are the ideal connectors for applications where weight and space must be kept to a minimum while maintaining maximum reliability. Typical applications for these connectors are data processing equipment, where shorter signal paths are needed, making it a perfect choice for radars, weapons systems, mission computers and displays, communications gear, and more.
