The Amphenol FCI D09S24A4PA00LF is a standard D-sub receptacle from the Delta D series, offering 9 positions in a 2-row layout with a vertical through-hole solder termination. It accepts the matching plug with the standard D-sub shell size 1 layout. The unthreaded housing/shell flange means it is intended for board-edge or panel-mount applications where the mating connector is secured by the enclosure or a separate bracket, not by jack-screws through the flange.
At 9 positions across 2 rows, the contact-to-contact spacing inside the shell is tight enough that the aggregate current through the connector is what drives the temperature rise, not any single circuit. For a signal interconnect carrying 5A per contact, this connector runs well within its thermal envelope.
Gold Flash Contacts and Mating Cycle Life
The tin-nickel plated steel shell handles the shield ground path and provides the mechanical robustness the D-sub form factor is known for.
