50-Position D-Sub Plug Housing for Harness Builds
The TE Connectivity AMPLIMITE HDP-20 1658641-1 is a 50-position D-sub plug housing designed for free-hanging (in-line) cable assemblies. It accepts crimp signal contacts — ordered separately — and mates with a standard 50-position D-sub receptacle (shell size 5, layout DD). The housing carries grounding indents on the shell for shield continuity, and the steel shell is tin-plated with a 200 µin (5.08 µm) finish thickness. Three rows of positions give the density needed for a 50-circuit harness without forcing an oversized connector footprint.
The shell layout is 5 (DD, D), meaning it mates with the corresponding 50-position receptacle housing. The unthreaded flange allows for mounting with a standard D-sub backshell or slide-lock hardware — no threaded inserts, so plan for a separate jack-screw kit if the application needs positive locking.
Grounding Indents and Shell Finish
The grounding indents on the shell mate with the receptacle's shell face to bleed shield current before it reaches the signal pins — a standard feature for EMI control in D-sub cable assemblies. The 200 µin tin plating on the steel shell provides corrosion resistance for indoor industrial environments; for outdoor or high-humidity runs, consider a stainless or nickel-plated shell variant from the same series.
