D-Sub HD Housing, 15 Positions — What's in the Box
It accepts female crimp contacts (sold separately) and mounts free-hanging in-line, making it the cable-side half of a wire-to-panel or wire-to-wire D-Sub interconnect. The 3-row layout packs 15 circuits into the standard 1 (DE, E) shell size — the same footprint as a 9-position standard D-Sub but with 15 contacts in the high-density arrangement. The shell is steel with a 200µin (5.08µm) tin plating, providing the EMI shielding expected from a metal D-Sub shell. The housing is black glass-filled polyamide (nylon), rated UL94 V-0 for flammability. The unthreaded flange accepts standard D-Sub hardware for panel mounting or jack-screw retention.
Contacts Not Included — The One Detail That Trips Every First Order
The most critical fact about the 1658681-1 is stated plainly in the spec: contacts are not included. This is a housing only. The housing accepts the contacts after they are crimped to the wire, and the terminal retention is built into the housing cavity. Do not order this thinking it is a complete connector assembly; it is the shell and dielectric only.
Mating and Termination — What Works with This Housing
The 15-position, 3-row high-density layout is keyed by the shell size — a standard DE-9 shell envelope but with the HD contact pattern. The unthreaded flange accepts the standard D-Sub slide-lock or screw-lock hardware for panel retention. For the female contacts, use the AMPLIMITE HDP-22 crimp terminals designed for this series — typically gold-plated for signal integrity and rated for multiple mating cycles. The housing cavities are polarized to prevent contact mis-insertion.
