The TE Connectivity 1658612-3 is a 15-position D-sub receptacle from the AMPLIMITE HDF-20 series, terminated via IDC to standard 26-28 AWG ribbon cable. It uses a free-hanging (in-line) mounting style, so it lands as a cable-end connector rather than a panel-mount or PCB-solder version.
Termination and Cable Prep
The IDC termination accepts 26-28 AWG stranded or solid wire — the insulation displacement forks pierce the ribbon cable jacket in one press operation. No stripping or crimping needed; a standard IDC hand press or pneumatic tool seats the cable in the slot. The feed-through feature means the cable passes through the connector body, simplifying daisy-chain or pass-through wiring in a harness.
Mating and Mounting
This receptacle mates with any standard D-sub plug (male) having the same shell size and layout. The unthreaded housing/shell flange means it uses a slide-lock or screw-lock retention system.
Ratings and Environment
Rated 1.25 A per contact — this is a signal-level current, not for power distribution. The gold contact finish at 30.0 µinch is thick enough for frequent mating cycles in corrosive or humid environments — a step above flash gold found on low-cycle consumer connectors.
