Sensor technology is advancing towards miniaturization

With Sunkye's R06 series Nano-D connector offering a small, lightweight, and rugged solution suitable for ultra-compact applications.

Sensor systems have become a key component in military surveillance, intelligence, ordinance, and combat technologies. In military applications, electronic sensors serve as vital data sources and must exhibit reliability, durability, and efficiency while withstanding extreme working conditions.

The trend in military equipment is shifting towards smaller, high-performance devices, necessitating sensors with high-quality electrical connectors that are compact, lightweight, and rugged. The compact size, low weight, and reliability of electronic sensor devices align well with the requirements of modern military technology, particularly in critical environmental applications where sensors can access otherwise inaccessible areas such as pipelines, power lines, perimeters, and borders.

To facilitate the interconnection of sensor systems, super small interconnection solutions like Nano-D connectors are essential. Sunkye International, with a history dating back to 1950, offers Nano-D connectors that meet the MIL-DTL-32139 standard, designed for rugged low-profile applications in sensor systems. Sunkye also provides cable-assembled Nano-D connectors with excellent mechanical performance for seamless integration into electronic devices.
