The NASA EEE-INST-002 provides instructions for choosing space connectors based on mission needs and requirements. Space connectors are utilized within the electronic equipment used in space applications, whether on a spacecraft or a satellite. To qualify for certain specific missions, the connectors must be tested and approved by NASA under EEE-INST-002 standards. Like all other components used in space, the connectors must also meet the stringent testing for outgassing (the release of trapped air) and residual magnetism to be suitable for use in space applications. These recommendations are laid out under NASA’s EEE-INST-002 guidelines for reliability.
NASA’s EEE-INST-002 has laid out three reliability levels of equipment that can be used for several space explorations. The term “Level” is attached to each component.
Connectors used in Level 1 and Level 2 space flight applications are highly-reliable. Examples of Level 1 or 2 may include connectors with a hood “clamping” mechanism surrounding the female contact engagement that is typically used with circular military socket contacts or the reverse gender “bulged wire twist” pin used with microminiature (Micro-D) style connectors.
Connectors used in Level 3 applications should also employ similar contact systems as those approved for Levels 1 and 2.
The following connectors are prohibited for Level 1 and Level 2 applications and are not recommended for Level 3 applications as well under the EEE-INST-002 standards.
