Board-to-board unshrouded header, 50 circuits
The 69157-150HLF is the 50-circuit member of Amphenol's BERGSTIK II unshrouded header line, a dual-row board-to-board interconnect on 0.100" pitch.
At 50 positions the 69157-150HLF sits between the 40-position and 60-position siblings in the same BERGSTIK II series — the 0.100" pitch, dual-row layout, and unshrouded push-pull fastening are shared across the range, so the board footprint stays constant; only the position count changes to match the circuit count.
