37-Position IDC D-Sub Receptacle for Ribbon Cable Harnesses
The TE Connectivity AMPLIMITE HDF-20 1658612-1 is a 37-position D-Sub receptacle that terminates ribbon cable via IDC — no individual wire stripping or crimping. Rated 1.25 A per contact with 30 µ" gold plating on phosphor bronze contacts, this is a signal-duty interconnect for parallel data or control buses running over flat cable.
IDC Termination — Wire Gauge and Cable Fit
The IDC termination accepts 26-28 AWG stranded or solid conductor ribbon cable. The insulation displacement forks pierce the jacket on each conductor simultaneously when the cover is pressed down — no pre-stripping, no solder. This makes the 1658612-1 a production-friendly choice for high-density signal harnesses where the cable assembly is built on a bench or an automated press.
The 1.25 A per-contact rating is consistent with signal-level current; this is not a power D-Sub.
