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.","metaTitle":"TE AMPLIMITE HDP-20 1658641-1, D-Sub Plug Housing, 50-Pos","metaDescription":"1658641-1 D-sub plug housing, 50 positions, 3 rows, free-hanging.
