9-Position D-Sub Plug, Male Pins, Through Hole
The 1731090448 is a 9-position D-Sub plug with male pins, part of the F series. It uses a through-hole mounting with solder termination — a standard layout for PCB edge connections in industrial control, data communication, and instrumentation where a reliable, field-serviceable interface is needed. The white shell color is a visual differentiator from the more common black or nickel variants, often used to identify a specific signal group or cable assembly in a panel. The steel shell with tin plating and grounding indents provides EMI shielding and a low-impedance ground path when mated with a compatible D-Sub receptacle. The housing/shell flange is unthreaded, so panel mounting requires screws or a separate threaded insert.
Through-hole solder termination means the pins pass through the PCB and are soldered on the opposite side — a mechanically robust joint suitable for manual assembly, wave soldering, or selective soldering. The 2-row layout with 9 positions follows the standard DE-9 (E shell size) footprint, which is pin-compatible with the vast majority of DB-9 PCB layouts. The unthreaded flange requires the installer to provide the hardware for panel mounting — typically a pair of 4-40 jackscrews or a threaded insert, depending on the mating receptacle. This keeps the connector body compact when panel mounting is not required.
The steel shell with tin plating provides corrosion resistance suitable for indoor industrial environments.
