Glenair’s Mod 429 upgrades Micro-D’s toNASA requirements without the need for a customer Statement of Work orSpecification Control Drawing. This section explains Glenair Mod 429ordering, and provides valuable information on outgassing and other spaceflight topics.how to order space grade micro-d’sKSix things you should knowabout Micro-D connectorsfor space flightOutgassing: What is1 outgassing, why is it important,and how does it affect connectorselection? Is special processingrequired to meet outgassingrequirements?2Screening: What is NASAscreening and what level ofscreening is required?3Magnetic permeability: Arenonmagnetic connectorsrequired?4Cryogenic exposure: AreMicro-D connectors suitablefor -200° C. exposure?5Materials: Micro-D connectorsoffer a variety of materials andplating finishes. Which ones arerecommended for space flight?6Wire Corrosion: M22759/33irradiated Tefzel® wire ispreferred for space applications.What about corrosion problemscaused by this wire?Step 1: Find a Standard Micro-D Part NumberElectroless nickel plated shells and Tefzel ® wire are preferred for space flight.Cadmium plating is prohibited.Step 2: Select a NASA Screening LevelThe term “Screening Level” refers to the final inspection procedure.Level 1 for mission-critical highest reliabilityLevel 2 for high reliabilityLevel 3 for standard reliabilityStep 3: Outgassing ProcessingA detailed explanation of outgassing is on the following pages. The interfacial sealon Micro-D receptacles does not meet NASA outgassing requirements unless it isbaked or thermal vacuum outgassed. Some customers specify deleting the seal,some opt for a bakeout, and some customers specify thermal vacuum outgassing.Both the bakeout and thermal vacuum outgassing are extra cost.Step 4: Select the Mod 429 Code that Matches the DesiredLevel of Screening and OutgassingUse the following table to choose the right modification code. Add the mod code tothe connector part number.
