9-Position D-Sub Plug for Signal Interconnects
The Molex 1731090622 is a 9-position D-Sub plug with machined male pins in a DE-9 shell layout — the standard footprint for RS-232, serial, and low-pin-count signal interfaces. It sits in the FCT 173109 series, a metal-shell D-Sub family built for industrial and data-communication environments where a shielded, screw-lockable interconnect is required.
Shell, Plating, and Environmental Range
Termination is solder to through-hole — the standard for D-Sub PCB mounting where mechanical retention from the solder joint and the shell's unthreaded flange provide the primary strain relief. The 2-row, 9-position layout matches the DE-9 footprint; the shell size 1 (DE, E) ensures the connector fits the standard cutout and mating receptacle. The white colour of the dielectric is a visual aid for assembly verification — it distinguishes this variant from black or blue insulators in the same series.
