“NXS connector with EMI Flange is provided with the contact know-how to resist knowledge as much as 50Gbit/s per channel, together with excessive ranges of vibration, shock, and climatic testing above 2,100G. Every ‘quadrax’ module [left] accommodates two twin twinax at 100Ω every pair, and it's blind-mateable, hot-pluggable, with low mating forces and low out-gassing,” in keeping with the corporate.

The NXS receptacle is solder-less, utilizing spring probes mating with gold plated goal pads on the PCB for each differential pair contacts and floor contacts. For reference: 4 module connector (above) is ~30mm lengthy, 12 module connector (beneath) is 60mm lengthy. Connectors with fewer methods can be found.

Constructed to area requirements, they're certified to requirements together with: ESCC 3401, ESCC 3402, ECSS-Q-ST-70C, ECSS-Q-ST-70-02, ECSS-Q-ST-70-08C, ECSS-Q-ST-70-38C and ECSS-Q-70-71.

Smiths Interconnect has 21 gross sales, R&D and manufacturing areas throughout 12 international locations, together with Canada, US, Mexico, Costa Rica, France, Germany, Italy, UK, Tunisia, India, China and Singapore.
