High-Density D-Sub Housing for 78-Position Cable Harnesses
The TE Connectivity AMPLIMITE HDP-22 1658674-1 is a D-sub high-density plug housing that accepts male crimp contacts. It carries 78 positions across 4 rows in a shell size 5 (DD, D) layout — the largest high-density shell in the standard D-sub footprint range. The housing is free-hanging (in-line), with an unthreaded flange for panel mounting with screws or rivets, and includes grounding indents on the shell for shield termination. The black glass-filled nylon (PA) body is rated for the full AMPLIMITE temperature range; the steel shell is tin-plated with a 200µin (5.08µm) finish for corrosion resistance in industrial and telecom environments. The plug mates with the matching AMPLIMITE HDP-22 receptacle housing (female contacts) of the same shell size and position count. The grounding indents on the shell provide a low-impedance path between the plug and receptacle shells when mated, which is essential for EMI screening in shielded cable assemblies.
