50-Position Shielded D-Sub Housing for Cable Assemblies
The TE Connectivity AMPLIMITE HDP-20 1658653-1 is a 50-position D-Sub receptacle housing for female crimp contacts. It is the shell and dielectric assembly only — contacts are ordered separately, a point that trips up first-time buyers who expect a loaded connector. The housing is free-hanging (in-line), shielded with a steel shell finished in tin plating, and uses a size 5 (DD, D) layout across three rows. The black glass-filled nylon dielectric handles the mechanical retention; the unthreaded flange lets you mount it with standard D-Sub hardware. Typical use is in shielded cable harnesses for data or signal interconnect where EMI containment matters — think industrial control cabinets, test equipment, or telecom racks.
What the Shielded Shell Means for Your Assembly
The steel shell with tin plating and 200 µin (5.08 µm) thickness provides a continuous ground path when mated with a shielded plug. The shield drains common-mode noise to chassis ground before it reaches the signal contacts — essential in electrically noisy environments like motor drives or switching power supplies. The free-hanging design means no board-mount footprint to worry about; you terminate the cable assembly at the workbench and install it in the field.
This housing accepts standard AMPLIMITE HDP-20 female crimp contacts (signal type). The three-row 50-position layout uses the standard D-Sub contact cavity arrangement; any HDP-20 female contact that fits the 20-24 AWG range will seat correctly.
