In Many Instances, Electronics Operating in Extreme Environments are Detecting, Collecting, and Processing Massive Amounts of Data without Human Involvement

Miniaturized connectors are enable to achieve greater functionality and portability in electronics.

The scope and expansion of today's electronic applications have increased the need for circuit design in extremely harsh environments. For example, navigation electronics are not only used for city street navigation but also play an important role in deep space exploration. As technology moves into harsh environments, there is a need to ensure that the design and material selection of these advanced systems can withstand the challenging conditions they will face. 

A variety of connectors support data acquisition, processing, and signal routing for these electronic devices. Connectors are often exposed to the most extreme environmental conditions surrounding their applications. For example, external sensors, camera systems, and extension arms or robots often operate outside the main equipment structure. The interconnections involved must be designed to withstand very rugged handling.

As circuit and sensor electronics evolve, they become smaller and run faster at lower voltages and currents. Micro-D and Nano-D connectors are becoming the standard interface from cable to circuit board or cable to instrument because they are lightweight and can absorb high vibration and shock conditions.

Sunkye Micro-D connector, a miniature high-speed rectangle connector used for military, aerospace, and other rugged, high-reliability applications, is available in arrangements from 9 to 100 contacts with 1.27mm contact spacing, specifying aluminum alloy shell with nickel, gold, or cadmium plating metal shell with the characteristic of transmitting quickly, reliably and securely. Highly portable, rugged, and reliable MIL-DTL-83513 Micro-D connectors are a very popular choice for harsh environment applications.

Sunkye Nano-D connectors feature MIL-DTL-32139 specifications and can be customized to different form factors that meet specialized requirements. Sunkye’s Micro and Nano miniature connectors are used in extreme environments and are super small and lightweight. Whether electronic equipment is often exposed to extreme temperatures or needs to be protected against dust, water, and corrosion, as long as there are requirements for extreme miniaturization, sealing, high density, lightweight, and high reliability, Sunkye connectors can be used.
