QR/P8-SC-221(15)

Hirose Electric Co Ltd's QR/P8-SC-221(15) delivers aerospace-grade performance in Backplane Connectors - Contacts for satellite communications. Meeting ESA ECSS-Q-ST-70-13 standards, this connector maintains signal integrity in vacuum conditions while withstanding 500 thermal cycles between -196 C and +150 C.The Signal implementation features outgassing-resistant materials with total mass loss <0.1% as per NASA outgassing tests. This prevents contamination of sensitive optical surfaces in space applications.Featuring Pin configuration with redundant contact paths, the design ensures mission-critical reliability. Each contact is individually rated for 10^8 operations in microgravity environments.The Crimp process utilizes cold-welding techniques suitable for space vacuum applications. The gas-tight joints demonstrate leak rates below 1 10^-9 mbar l/s when tested with helium mass spectrometry.Designed for 24-28 AWG aerospace wiring, the connector accommodates both MIL-W-22759 and AS22759 wire types. The strain relief system prevents micro-cracking in zero-G cable management scenarios.Gold surface treatment includes gold-over-nickel diffusion barriers that prevent intermetallic growth. Extended life testing shows contact resistance stability through 15 years of simulated GEO orbit conditions.
