Company insight


continue to shrink, they must also be capable of withstanding the harsh conditions in which drones operate. Interconnect companies, like Omnetics, have risen to the challenge of creating smaller connectors that meet rigorous qualifications while maintaining a compact form factor.


Omnetics’ miniature 38999 circular connectors, designed to specifications similar to the older version of MIL- DTL-38999, offer the capability to handle 3A on 24-30AWG wire. These connectors assure UAV customers that smaller interconnect solutions can provide the same high qualities of signal integrity and data transmission, regardless of reductions in size and weight.


Changing payloads and high data transfer rates UAVs designed for payload delivery and remote sensing have experienced increased flight times due to the miniaturisation of electrical components. Drones now host a wide variety of sensors and electronics, including Light Detection and Ranging (LiDAR), Forward-Looking Infrared (FLIR)


thermal sensors, First-Person View (FPV) cameras, lasers and radars. To capture high-quality video, drones rely on gimbals to stabilise camera systems and sensors, even in challenging weather conditions. As technology advances, the demand for additional sensors and higher data transfer rates continues to grow. Smaller connectors have not hindered the ability to transmit large volumes of data through smaller gauge wires and fibre optics. For tasks like Lidar and 3D mapping, where millions of data points must be processed onboard before transmission, low-latency data transfer is essential. This ensures productive communication between drone pilots and UAVs for aggregating large data files.


Meeting the challenges with high- speed connectors As UAVs become more sophisticated, there is a growing need for high-speed connectors. Lightweight military UAVs are equipped with cameras, weapons, GPS modules and other detectors, all requiring high-resolution video transfer.


These connectors must meet impedance requirements, which were not previously a concern. Moreover, connectors must address electromagnetic interference (EMI) issues. Lightweight metallised braids may be added to enhance signal strength and shield cables to ensure proper signal integrity. Omnetics connectors provide high


density, unparalleled reliability and high- speed data transfer in various packaging options, making them a preferred choice for UAV designers and manufacturers for all onboard flight hardware. In conclusion, the evolution of circular connectors is revolutionising UAV technology, enabling these versatile devices to operate more efficiently and effectively across various industries. As drones continue to evolve and find new applications, connector advancements will remain a crucial element in their success. Companies like Omnetics are at the forefront, providing innovative solutions that meet the demanding requirements of modern UAVs. ●
