78-Position High-Density D-Sub Receptacle Housing
The TE Connectivity 1658685-1 is a 78-position D-Sub, High Density receptacle housing from the AMPLIMITE HDP-22 series. It accepts female crimp contacts and is designed for free-hanging (in-line) mounting, making it a standard choice for high-density cable harnesses where panel space is tight and pin count is high. The housing uses a 4-row configuration within a shell size 5 (DD, D) layout — the largest standard D-sub shell size, which provides the physical real estate for 78 signal contacts in a single connector body.
Shell and Shielding Construction
The shell is steel with a tin plating finish at 200µin (5.08µm) thickness.
