SH400 and SH403 IDC Ribbon Cable Headers

Description

IDC ribbon cable connections

ULO-SH400 and ULO-SH403 use a two-row contact interface with 2.54mm longitudinal pitch and 2.54mm row spacing. The IDC cable and cover pitch is 1.27mm. SH400 adds long ejectors with two latch-height options; SH403 has a compact body and an optional strain-relief arrangement. Select the exact model, total contact count and mounting-hole configuration before sizing the cable assembly.

The ordering fields differ between models. SH400 does not list 20- or 34-contact versions, and its strain-relief field lists only N. The screw-hole option identifies the housing configuration; screw size and supplied fastening hardware are unspecified.

For both models, N is half the total contact count and A = (N−1) × 2.54mm. A is the first-to-last contact span within one mating row. Use the illustrated endpoints for each additional length; the cover pitch and mating-contact pitch describe different parts of the assembly.
