Backplane receptacle for VITA 41 systems
The TE 1410420-1 is a 176-position MULTIGIG RT1 receptacle built to the VITA 41 full stand-alone standard. It carries 128 single signal contacts and 48 dedicated ground blades in an 11-row by 16-column grid at 1.80 mm pitch. The press-fit tails go into a backplane without solder — the compliant pin compresses into the plated through-hole, which is the standard termination for high-reliability telecom and military backplanes where rework matters.
What the press-fit and gold mean for a backplane build
Press-fit termination avoids the thermal cycle stress of wave soldering on a large backplane — the compliant beam holds retention force mechanically. The 50.0 µin gold thickness is standard for the mating cycle count in a card-cage environment; it resists fretting corrosion from vibration and repeated insertions. The 1.80 mm pitch keeps the board routing manageable for differential pairs at 10+ Gb/s, though the signal-to-ground ratio of 128:48 means you rely on the ground blades between columns for return current, not a full ground-per-signal grid.
