8976 Series, Robotics and EVA - SOURIAU - #1

In the frame of Space Station Alpha program, SOURIAU has developed and qualified a series of high reliability rectangular connector for robotic operations. This hardware is used on the SSRMS (Space Station Remote Manipulator System) which is the Canadian contribution to the Space Station. These connectors feature :

• Low Insertion Force contacts

• Thermal differential (between plug and receptacle) compatibility

• Integrated misalignement catching system

• High durability (6000 operations)

• High EMI shielding efficiency

• Associated dismountable EMI backshells

• Deep space environment (Atox) compatibility

• Easy inspection, maintenance or repair after wiring.

Contact resistance as per MIL-C 39029

Mass

• < 105 g for plug

• < 76 g for MSSP⁽¹⁾ receptacle

• < 218 g for ORU⁽²⁾ receptacle

ORU receptacle misalignment

• Aa = ± 0,5° • AY = 1,27 mm

• Aß = ± 0,5° • AZ = 2,03 mm

• Ay = ± 0,5°

ORU receptacle overstroke • AX = 2,29 mm
