The Hirose DF37NB-24DS-0.4V(53) is a 24-position, 0.016" (0.40mm) pitch FPC/FFC receptacle from the DF37 series. It is a surface-mount, dual-row, center-strip contact connector designed for board-to-board or board-to-flex interconnects where a low 0.038" (0.97mm) mated stack height is required.
The 0.038" (0.97mm) height above board sets the z-axis clearance between stacked PCBs; the mated stack height of 0.98mm means the total gap between boards is under 1mm, which drives the enclosure design.
The connector uses surface-mount termination — the contacts are soldered directly to pads on the PCB. No crimping or wire termination; the FPC or FFC is inserted into the mating plug, which then mates with this receptacle. The 24 positions carry 24 individual signal lines; the dual-row layout keeps the connector body narrow despite the high circuit count.
Position Count Comparison Across the DF37 Series
The DF37NB-24DS-0.4V(53) carries 24 positions. The same-series sibling DF37NB-20DS-0.4V(51) carries 20 positions, and the DF37NB-30DS-0.4V(51) carries 30 positions — all at the same 0.016" (0.40mm) pitch and 0.038" (0.97mm) height. The position count is the only selection variable between these three; the footprint length scales with the number of contacts.
