It uses a 0.049" (1.25mm) pitch — the critical dimension that must match the mating header or ribbon cable pitch.
Procurement Reality — Obsolete Status
The GHDR-20V-S(F) is listed as obsolete. Do not treat this as a standard-stocked line; plan for a last-time-buy quantity or a cross-reference search to a current-production GHD-series housing with the same 20-position, 2-row, 1.25mm pitch configuration.
The housing accepts crimp termination, so the wire is terminated to the contact first, then inserted into the housing.
Pitch and Position Fit
The 0.049" (1.25mm) pitch is the defining board-layout dimension. At 20 positions in 2 rows, the overall width across the housing is approximately 12.5mm (10 positions per row × 1.25mm). This pitch is common in compact consumer and industrial electronics where board space is tight. The 2-row layout gives a higher density than a single-row 20-position housing at the same pitch, but the mating header must also be a 2-row, 20-position, 1.25mm pitch part from the GHD series.
