Docking Connector for Parallel Board Interfaces
The TE Connectivity 2129392-2 is a 70-position receptacle from the CHAMP series, designed as a docking connector with outer shroud contacts. The shroud protects the signal pins during blind mating, which is the typical use case in docking stations or parallel board-to-board interfaces where alignment isn't perfect on first engagement. The connector supports both surface mount and through-hole solder termination, giving the layout engineer flexibility in board attachment method.
Position Count and Contact Layout
With 70 positions across 2 rows, this receptacle carries a dense signal count for a docking interface. The outer shroud contacts arrangement means the signal contacts are recessed behind the shroud wall, which adds a layer of mechanical protection during mating. The board guide feature assists alignment when the connector halves are brought together — without it, the 70 pins could bend on a misaligned dock insertion.
Plating and Termination Choices
The 15.0µin gold contact finish is the standard thickness for moderate-cycle docking applications — enough to maintain low contact resistance through hundreds of mates without the cost of heavy gold. The solder termination accepts both surface mount and through-hole processes, so the same part can be used on a standard reflow line or a wave-solder board. The Tape & Reel and Cut Tape packaging options suit volume pick-and-place or prototype hand-assembly.
