50-Position D-Sub Receptacle Housing for Harness Assembly
The TE Connectivity AMPLIMITE HDP-20 1658640-2 is a 50-position D-sub receptacle housing designed for free-hanging (in-line) cable termination. The 3-row layout uses the size-5 (DD) shell arrangement, giving you 50 signal contact positions in a standard D-sub footprint. The shell is steel with a yellow chromate-plated zinc finish, providing corrosion resistance for industrial cabinet or equipment interconnect applications. The unthreaded flange accepts standard D-sub hardware for panel mounting, though the connector is rated for free-hanging use.
Mating and Contact Fit
This receptacle housing mates with any standard AMPLIMITE HDP-20 size-5 (DD) D-sub plug housing. The 50-position, 3-row layout is fixed — confirm your mating half uses the same shell size and row count. The housing accepts size-20 crimp contacts (20-24 AWG typical), which are inserted from the rear and retained by a metal clip or plastic retainer depending on the contact variant. The shell finish thickness is 200 µinch (5.08 µm) of yellow chromate over steel.
