The Hirose DF9-9S-1V(69) is a 9-position receptacle from the DF9 series, designed for parallel board stacking with a mated stack height of 4.3 mm. Gold-plated contacts (8.00 µin) on the mating interface handle repeated connect-disconnect cycles better than a tin finish would, which matters for a connector that may see field service or calibration swaps.
Position Count and the BOM Line
The 9 positions of the DF9-9S-1V(69) are the first procurement check — the circuit count on your harness or board design must match exactly.
The base product number is DF9-9, and the (69) suffix denotes the gold-plated, tape-and-reel packaged variant.
