These cable sockets use insulation-displacement terminations. Select the complete model, mating contact pitch, row spacing and contact count. Mating pitch does not by itself establish ribbon-cable conductor pitch, wire size or compatibility with another connector.

A is overall length and B is the end-contact span. Their tolerances are ±0.3mm and ±0.2mm respectively. The contact pitch and row spacing are 2.54±0.1mm. Body references include 6mm width, 7mm height, 2.25±0.15mm contact projection, 0.3±0.05mm contact detail and 1.15±0.1mm termination reference. The cover sketches show 10.40mm and 13.50mm overall references, 4.30mm and 2.30mm upper widths and a 0.90mm edge reference; they are not a single assembled-height specification.

With N contacts per mating row, overall length is 1.27×N+4.75mm and the longitudinal contact span is 1.27×N−1.27mm. The mating interface uses 1.27mm longitudinal pitch and 2.54mm row spacing. The housing is 5.90mm wide with 6.60mm and 5.25mm height references, a 2.50mm key width and 0.90mm key projection. End-view references are 4.90mm and 4.42mm widths with 1mm and 1.15mm termination details. The cover has a 7.60mm height reference, 1mm lip and 1.25mm internal reference.
With N contacts per row, housing and cover length is N×2mm+5.2mm with ±0.5mm tolerance, and contact span is (N−1)×2mm. Mating pitch and row spacing are 2±0.1mm. Body references are 4.20mm width, 5.45mm height, 1.90mm contact projection and 4.80mm end-view width. The cover references are 8.80mm and 7.30mm high with 4.20mm width.
N equals the total contact count divided by two. The drawing defines A=1.27×N−0.635mm and B=1.27×N+4.19mm. Longitudinal mating span is 1.27×(N−1)mm. Both mating pitch and row spacing are 1.27mm. The cover is 4.95mm high, with 3.05mm width, 2mm upper width, 1.85mm step and 0.635mm offset. Housing references are 3.20mm height, 3.05mm width, 1.90mm central key width, 0.635mm termination pitch and 1.80mm terminal projection.
Cable conductor size and validated cable pitch are unspecified; match the cable and termination tooling to the exact socket instead of treating the mating pitch as a cable specification.
