The Amphenol L717SDB25PVFC309 is a standard-density D-Sub plug with 25 male pins arranged in two rows — the DB-25 shell size (3, DB, B) that matches the classic parallel-port and serial-interface footprint. It terminates via solder cups, so the build-to-print shop needs the wire stripped and tinned, not a crimp tool. The shell carries grounding indents that contact the receptacle shell before the signal pins mate — that sequence bleeds ESD and shield current to ground before the circuit closes. The flange comes with female screwlocks (4-40 thread) on the mating side, so the cable plug locks to the panel-mount receptacle with a standard UNC 4-40 jack-screw. If the buyer is asking 'Does it have a locking screw?', the answer is yes — the screwlock is built into the flange.
For a harness carrying 24 AWG or 20 AWG signal wires, the 3A per pin is adequate for RS-232, RS-422, PLC I/O, or instrumentation loops. Tin-plated contacts would fret under vibration at lower cycle counts; the gold here gives the mating surface a longer service life before wear-through.
Termination and Assembly Notes
Solder-cup termination: each pin has a cup that accepts a stripped wire end — 20 AWG is the listed maximum. The assembly sequence is: strip, tin, solder into the cup, then slide the backshell over the cable and screw it to the connector body. The stamped contact form means the pins are formed from sheet metal rather than machined from bar stock. For a cable assembly that will be mated a few hundred times over its life, stamped contacts are the standard choice.
