Connectors for space applications

The compact and lightweight Gecko, high-density Datamate, and the high-power Kona series are all part of Harwin’s high-reliability (Hi-Rel) interconnect portfolio. Every interconnect solution in the HRi line is intended for mission-critical environments like satellites, aerospace, and defence, where optimised size, weight, power, and cost (SWaP-C) alongside high performance and guaranteed dependability are essential.

The smallest and lightest power/data combination connectors in their class, the Gecko-MT series presents engineers with an attractive alternative to the Combi-D/Micro-D format. To meet industry demand for a greater scope of options, Harwin has scaled up the number of variants with a non-symmetrical structure featuring two to six power contacts (10A) at one end and 4 to 24 signal contacts (up to 2.8A) at the other.

As with the symmetrical two-power/eight-signal and four-power/eight-signal variants, the new additions have high resilience to shock and vibration. They support an extended -65°C to 150°C operating temperature range, with 1,000 (minimum) mating cycle durability. These connectors display strong outgassing properties and are fully aligned with the stringent directives set by both the NASA and ESA space agencies. Vertical and right-angle configurations are available as well as accompanying cabling. 

Harwin’s Datamate and Datamate Mix-Tek connectors are suited to use in space applications and have a long track record. Standard contacts in the series have a 3A rating, while the Datamate Mik-Tek contacts can deliver up to 40A. With small footprints, these SWaP-C optimised 2mm-pitch components take up only minimal board real estate. The structure of these connectors has high resilience to extreme shock and vibration. In addition, their ability to withstand temperatures of up to 125°C, plus low outgassing properties are also highly advantageous.
