The Molex 1731092488 is a standard-density D-Sub receptacle from the F, FCT 173109 series, with 9 positions arranged in 2 rows — the classic DE-9 (E shell size) layout. It is a through-hole, solder-terminated female connector with a steel shell and tin-plated finish, designed for reliable signal interconnection in industrial control, data communication, and test equipment.
The 9-position, 2-row arrangement follows the standard pinout — compatible with any mating male D-sub plug. The -55°C to 125°C temperature range means it can live in an unheated cabinet or near a hot power supply without derating. The steel shell with tin plating provides basic EMI shielding when mated to a matching plug with a grounded backshell.
