The Hirose DF51K-24DS-2C(800) is a 24-position receptacle housing from the SignalBee™ DF51 series, built for wire-to-board interconnect in compact electronic assemblies. It uses a 2.00 mm pitch with matching 2.00 mm row spacing, giving you a dual-row layout that fits a 24-circuit harness into a board footprint about 24 mm long. This is the 24-circuit member of the DF51K sub-series, which shares the same 2.00 mm pitch and dual-row layout across position counts from 16 to 24.
Contacts Are Ordered Separately — Don't Forget the Crimp Terminals
Common compatible terminals are the Hirose DF51-2428SCF (for 24-28 AWG) or DF51-2830SCF (for 28-30 AWG), depending on your wire size.
Mating Plug and Locking Ramp
For a 24-circuit dual-row header, look for the DF51K-24DP-2C series or the through-hole version DF51-24DP-2DSA. The locking ramp is the feature that keeps the pair mated in equipment that sees shock or vibration — without it, a wire tug can separate a plain friction-lock connector.
The DF51K series offers the same 2.00 mm pitch and dual-row layout in 16, 18, 20, and 24 positions. The DF51K-24DS-2C(800) gives you 24 circuits — that's 4 more than the DF51K-20DS-2C(800) and 8 more than the DF51K-16DS-2C(800). The housing length scales with position count, but the pitch and row spacing stay constant, so the mating header footprint is a straight extension of the same pattern. If your BOM calls for 24 signal lines, this is the one; if you're populating fewer circuits, the 20- or 16-position housing saves board space.
