Product details
The 1731120212 by Molex pioneers D-Sub, D-Shaped Connectors - Contacts technology for space-grade applications. These radiation-hardened contacts maintain signal integrity in orbital environments while withstanding extreme thermal cycling.Qualified for Signal spacecraft systems, the contacts exceed ESA ECSS-Q-ST-70-60 outgassing requirements. Testing shows <0.1% total mass loss and <0.01% collected volatile condensable materials.The Female Socket configuration utilizes redundant contact points for mission-critical reliability. Testing confirms 100% functionality after 10^9 mechanical cycles in vacuum.Space-grade Machined manufacturing prevents cold welding in vacuum. Surface analysis shows <5 surface roughness to minimize atomic-scale adhesion.Designed for 18-22 AWG spacecraft wiring, the contacts withstand 500 thermal cycles from -190 C to +150 C. Testing per MIL-STD-883 Method 1010 shows zero mechanical failures.Crimp methods are validated for zero-gravity assembly. The solder variant demonstrates perfect fillet formation in vacuum reflow conditions.The Copper Alloy composition is optimized for radiation environments. Testing shows <5% resistance change after 100krad(Si) total ionizing dose exposure.Gold coating prevents tin whisker formation in space vacuum. SEM analysis confirms zero whisker growth after 5000 hours at 85 C/85%RH followed by vacuum bake.With 51.2µin (1.30µm) deposition, the contacts maintain stable emissivity characteristics. Testing shows <5% variation in thermal radiative properties after UV exposure equivalent to 5 years GEO.The 20 geometry is optimized for high-density spacecraft avionics. Micro-CT scanning confirms zero mechanical deformation after 100G mechanical shock testing.
