6-Position Dual-Row Vertical Header
The 2-1971906-3: The 3.30 mm pitch and 5.20 mm row spacing set the board footprint — a common spacing for industrial wire-to-board harnesses where the header mates with a receptacle housing. The kinked pin termination provides a mechanical lock in the plated through-hole before soldering, reducing tombstoning during wave solder.
The header includes a board guide feature to align the mating receptacle during blind mating — reduces off-angle insertion that can damage pins.
