Aptiv, Winchester Unveil Modular Connector for Satellite, Drone Programs

Swiss technology company Aptiv PLC and its American subsidiary Winchester Interconnect have introduced a modular connector tailored for satellites and unmanned aerial systems.

Called Modulus, the solution is designed to transmit signals, data, and power between terminals and devices.

It blends high-speed single-pair ethernet and configurable power in a compact, field-serviceable design, allowing users to optimize development and maintain equipment.

Additional features of the platform include a standardized interface and durability for complex domains, making it ideal for low-earth orbit satellite constellations and tactical drone missions.

“Modulus provides engineers with the configurability they need in one platform … while maintaining the ruggedness demanded by space and defense applications,” said Joseph Massaro, vice chair and president of Engineered Components at Aptiv.

“Modules can be mixed and matched, and replaced in the field, ensuring quick maintenance and minimal downtime.”

‘Truly Modular Architecture’

The consortium noted that Modulus meets the demand for smaller size, reduced weight, and lower power consumption in defense programs, all while sustaining high performance.

By integrating Aptiv’s reliable connector technology with Winchester’s know-how, Modulus is expected to serve as a versatile solution that adapts to evolving requirements, eliminating the need for complete connector redesigns.

“The biggest challenge was maintaining signal integrity and power performance on a truly modular architecture,” said Clint Schlosser, senior product manager at Winchester Interconnect. 

“Each module carries stringent high-speed data requirements while sitting next to power and signal contacts in a small footprint. Modulus addresses that with controlled impedance, contact geometry optimization, and ruggedized materials.”
