D-Sub Plug for Shielded Cable Assemblies
The Molex 1731091078 is a 9-position D-Sub plug (DE-9 shell size) with machined male pins arranged in two rows. It terminates via through-hole solder to a PCB and carries grounding indents on the metal shell — these bleed shield current from the cable braid before it reaches the signal pins, which matters for EMI compliance in shielded harnesses.
Rated 5 A per contact. The machined copper alloy contacts support repeated mating cycles typical of field-service connections.
Mates with any standard receptacle of the same shell size DE-9. The unthreaded housing flange accepts a standard D-sub backshell or hood with jack-screws for locking. Through-hole solder termination — the pins insert into plated through-holes on the PCB and are wave-soldered. No press-fit or SMT reflow profile needed, which simplifies the assembly line for a contract manufacturer.
