The TE Connectivity 1658641-3 is a 50-position D-sub plug housing from the AMPLIMITE HDP-20 series, arranged in 3 rows and sized for shell layout 5 (DD, D). The shell is steel with yellow chromate-plated zinc finish, 200 µin (5.08 µm) thick, and includes grounding indents that mate with the receptacle shell to bleed shield current before it reaches the signal pins. The housing is black glass-filled nylon (PA), rated for use in shielded cable harness assemblies where a standard-density 50-pin D-sub interface is required.
Shell Size and Mating Fit
The shell size is 5 (DD, D) per the connector layout designation. The mating receptacle must also be a DD-5 shell.
This housing is a plug for male contacts — it accepts standard AMPLIMITE HDP-20 crimp contacts (sold separately). The contact type is signal, so the housing is designed for discrete wire termination using the appropriate size crimp terminals. The package is bulk, so the housing ships individually, not on a tape or tube.
