The Hirose DF40TC-34DS-0.4V(58) is a 34-position, 2-row receptacle with center strip contacts, part of the DF40T series. At 0.016" (0.40mm) pitch, it's designed for high-density board-to-board stacking in compact electronics — think smartphones, wearables, or module-to-mainboard interconnects where every millimeter of PCB real estate counts.
Mounting and assembly notes
Tape & Reel packaging (also available in Cut Tape) feeds directly into a pick-and-place nozzle — no manual handling required. The 1.5mm stack height is low enough that the mating header sits flush against the board, so no extra standoffs are needed in a thin-profile build.
