Product details

DB-25 Male Plug for Signal and Low-Power I/O

The Molex 1731091399 is a 25-position D-Sub plug (male pin) from the F, FCT 173109 series, built for standard DB-25 signal interfaces.

Pinout and Mating Half

This plug uses shell size 3, layout DB-B — 25 male pins in two rows. It mates with any standard D-Sub receptacle of the same shell size. The unthreaded housing/shell flange accepts a standard D-Sub backshell or slide-lock hardware.

Shielding and Grounding

The shell material and finish are steel with tin plating, offering corrosion resistance and a solid ground reference for cable-braid termination.
