D-Sub Housing for Male Crimp Contacts — 9-Position Plug Shell
The TE 1658645-1 is a 9-position D-sub plug housing from the AMPLIMITE HDP-20 series, designed to accept male crimp contacts for field-terminated cable assemblies. It uses the standard DE-9 shell layout (E shell size) with two rows of positions, matching the ubiquitous DB-9 footprint for serial, industrial control, and instrumentation interfaces. The shell is steel with a tin-plated finish (200 µin thickness) for EMI shielding, and the black glass-filled nylon insert provides the dielectric isolation between contacts. The unthreaded housing/shell flange accepts standard D-sub slide-lock hardware for mating retention. Contacts are not included.
Shielding and Shell Construction
The steel shell with 200 µin tin plating provides a conductive path for shield current from the cable braid to the mating receptacle shell, reducing radiated emissions in electrically noisy environments. The tin finish is compatible with standard D-sub backshells that ground through the shell-to-shell interface. For unshielded applications, the same housing accepts a non-metallic backshell, but the metal shell itself adds mechanical robustness over all-plastic D-sub housings.
Wiring and Contact Assembly
Wire the housing by crimping individual male contacts onto 20-24 AWG wire, then inserting them into the cavity positions until the retention tang locks. The two-row layout follows the standard DE-9 pin arrangement: 5 positions in the top row, 4 in the bottom. The glass-filled nylon insert resists the insertion force of the contacts and maintains position under cable strain. After loading all contacts, fit a backshell over the cable exit and secure it to the threaded standoffs on the shell.
This plug housing mates with any standard DE-9 size D-sub receptacle (female) housing, including the TE AMPLIMITE HDP-20 1658645-2 (9-position receptacle housing). The 1658645-2 is the female counterpart — same shell size, same mounting style, accepts female crimp contacts. Both use the same slide-lock hardware and backshell options. For a complete connector pair, order the plug housing (1658645-1), the receptacle housing (1658645-2), and the appropriate male/female crimp contacts.
