Favored by UAV designers and manufacturers for all onboard flight systems, Omnetics connectors offer high-density, reliability, and high-speed data transfer in a variety of packaging options.
As the push toward miniaturization continues, UAV manufacturers recognize the need for smaller interconnect solutions to accommodate the increasing number of applications being integrated into ever-smaller devices. The size of drones is influenced by their intended purpose, which also dictates their power requirements and sensor capabilities.
For instance, as drones have become smaller, it has allowed architects and civil engineers focused on infrastructure and building integrity to inspect both internal and external pipelines for cracks, as well as assess structural frameworks by sending back images with low-latency signal data and high-resolution video (up to 4k).
This has contributed to a reduction in worker casualties across industries, as appropriately sized drones can access difficult-to-reach areas.
While small hobbyist drones are available for personal and recreational use, the primary driver of miniaturization lies in industrial drones that require high reliability for carrying out critical tasks in often challenging environments. As a result, suppliers of interconnects, electronics, and other materials for drone manufacturers must meet the demand for durable, long-lasting equipment.
Tailored Interconnect Solutions
Specialized applications necessitate interconnect solutions that can accommodate the broad range of drone types. In custom drone designs, there is often a requirement for hybrid connectors that support both power and signal transmission within a single housing. This approach combines two separate connectors into one, saving space and allowing more room for additional hardware.
As UAV connectors become smaller, they must still endure the shock, vibration, and harsh conditions encountered in drone operations. Companies like Omnetics have adapted to the growing customer demands by developing smaller connectors capable of meeting stringent qualifications on a reduced scale.
The miniature 38999 circular connectors have been adapted to the specifications of the older version of MIL-DTL-38999, due to their compact size and capacity to handle 3A on 24-30 AWG wire.
Omnetics’ UAV clients reportedly appreciate that these smaller interconnect solutions can maintain the same high standards for signal integrity and data transmission, even as size and weight are minimized.Evolving Payloads
Changing Payloads
UAV manufacturers focusing on payload deliveries to remote areas have seen extended flight durations as a result of shrinking electronic components.
Drones are now incorporating a growing number and variety of sensors and electronics mounted on their frames and gimbals to suit specific applications, such as Light Detection and Ranging (LiDAR), Forward-Looking InfraRed (FLIR) thermal sensors, First-Person View (FPV) cameras, lasers, or radar systems.
High-quality video footage is nearly impossible without gimbals to counteract vibration and shock. Gimbals mounted on UAVs function as gyroscopes with motors to stabilize camera systems and sensors during flight, regardless of whether the drone is piloted or autonomous, even in extreme weather conditions.
As technology advances, the need for more sensors on drones and an increase in data transfer speeds continues to grow. The shrinking of interconnects has not diminished the ability to transmit large amounts of data through smaller-gauge wires and fiber optics.
In scenarios involving LiDAR and 3D mapping, the vast amounts of data points collected may need to be processed onboard before being transmitted to the command center. Low-latency data transfer is crucial for effective communication between UAVs and their operators, ensuring smooth aggregation of large data files.
In addition to the size and weight considerations, many other factors come into play. There is a growing need for high-speed connectors, as lightweight military UAVs often carry cameras, weapons, GPS modules, and other sensors.
These drones are also required to process large volumes of high-resolution video, which must be transferred through connectors that now face impedance requirements that were not a concern previously.
These connectors also play a role in minimizing electromagnetic interference (EMI). Adding lightweight metalized braids can address key concerns with signal strength, ensuring that the cable to the sensors is properly shielded and maintaining strong signal integrity.
