The Amphenol L177DE09S is a standard-density D-sub receptacle with 9 positions in a DE-size shell — the layout you find on RS-232 serial ports, industrial control interfaces, and test-equipment I/O panels. It uses solder-cup termination, so you can terminate individual wires with just a soldering iron and heat-shrink, no crimp tool or die set required. That current rating is higher than the typical 5 A per contact for a standard-density D-sub, so this part can handle a mix of signal and moderate power on the same shell — say, a +24 V supply line alongside a few data pairs.
Termination and Field Fit
Solder-cup termination: strip the wire, tin it, insert into the cup, and solder. The machined contact takes the heat without wicking solder up the barrel. Mates with any standard DE-9P male D-sub plug — the shell layout is fixed by the D-sub interface standard, so the footprint is universal. If you need a panel-mount version, add a backshell with a cable clamp and the unthreaded housing shell accepts a 4-40 jack-screw kit for the mating half. On a field-repaired cable that gets reconnected weekly, that matters: the gold wipes clean on each mate and doesn't oxidise between connections.
