PCB connector 154 series

for aircraftSMCwire-to-board

Overview
SMC series PCB connectors deliver a compact 1.27 mm pitch for high-density board-to-board and wire-to-board interconnects. Available in 12–80 positions with multiple row/column and stacking options, they suit space-constrained designs while ensuring reliable signal paths via polarized housings and gold-plated mating areas.
