Features and Benefits

In crucial aerospace and defense systems, interconnects must maintain exceptional electrical integrity and mechanical reliability despite extreme temperatures, vibration and environmental stress. These connections must also be high-density in order to optimize the use of limited space while offering flexible termination and circuit-count options to support diverse architectures and enable scalability.

Using high-density PCB connectors qualified to MIL-DTL-55302 specifications ensures the components are reliable and durable enough for aviation, defense and space applications. Solutions meeting this specification also enhance flexibility and simplify maintenance by supporting interchangeability with other compliant connectors.

Molex’s AirBorn R Series MIL-DTL-55302 0.075" Rectangular Connectors are rugged, high-density and high-reliability connectors qualified to stringent MIL-DTL-55032 specifications. These connectors have flight heritage and a proven record of success in space-constrained aerospace, defense and space applications, including use on the space shuttles, Mars Rovers and numerous defense platforms. A four-point contact system enhances durability and helps ensure stable electrical connections in high-vibration and high-shock conditions. Multiple termination options, configurations and circuit counts from 10 to 604 contacts contribute to the design’s versatility and support scalable system density, while a 0.075" high-density contact pitch enables use in compact devices.

MIL-DTL-55302 Qualification

Designed for aerospace and defense systems requiring verified ruggedness and long-term reliability, AirBorn R Series connectors meet or exceed stringent military specification MIL-DTL-55302 for performance in applications subject to extreme temperatures, vibration, shock and moisture. These connectors are also interchangeable with other compliant MIL-DTL-55302 connectors, simplifying inventory and maintenance challenges.

Ruggedized Design for Extreme Environments

The contact design features four points of contact, helping ensure consistent electrical connectivity, enhance signal integrity and reduce the risk of intermittent connectivity in essential systems and harsh aerospace or defense environments.

Flexible Customization Options for Termination and Mounting

These connectors support solder-cup, plated through-hole, crimp-removable contacts, press-fit compliant, card-edge, surface-mount and flexible-circuit terminations. This enables flexible integration with a variety of PCB architectures, reducing design complexity and shortening assembly time.
