IDC D-Sub Plug for Ribbon Cable Harnesses
The TE Connectivity AMPLIMITE HDF-20 1658615-4 is a 9-position D-sub plug with male pins, terminated via IDC to 26-28 AWG stranded or solid ribbon cable. This free-hanging (in-line) plug uses the standard DE-9 shell layout, mates with the matching AMPLIMITE HDF-20 receptacle, and carries gold-plated phosphor bronze contacts rated 1.25 A per circuit. This is the IDC variant of the HDF-20 series, designed for mass-termination of ribbon cable in high-density signal interconnects.
IDC Termination vs. Standard D-Sub
The 1658615-4 differs from a standard solder-cup D-sub in its termination: IDC (insulation displacement) for ribbon cable, not individual wire soldering. The gold-plated contacts are rated for signal-level current (1.25 A per circuit), consistent with the ribbon cable's current capacity. The unthreaded flange is a housing/shell feature — it accepts a jack-screw kit if the application requires locking, but the plug itself ships without hardware.
The gold contact finish on phosphor bronze provides corrosion resistance for moderate mating-cycle applications — not a high-cycle field-service connector, but reliable for harnesses that are mated a few times over their service life.
