It uses the DE (E) shell layout with 3 rows of contacts, packing 15 signal circuits into the same panel cutout that a standard-density DE-9 would occupy. Typical applications include serial I/O ports, industrial control interfaces, and test equipment where a compact, shielded signal interconnect is needed.
Board Lock Retention and Soldering
This receptacle includes board locks — metal retention features that snap into the PCB during through-hole insertion. For a D-sub in a panel-mount application, the board locks are the difference between a connector that stays aligned through the panel cutout and one that shifts during the soldering process.
Mating Half and Shell Hardware
The 2317171-1 mates with a high-density D-sub plug of the same DE (E) shell size and 15-position layout. The receptacle carries threaded 4-40 inserts in the housing/shell flange — these accept the jackscrews from the mating plug to lock the pair together. The 4-40 hardware is standard for this shell size; the same screw spacing is used across the AMPLIMITE HD-22 series.
