The 30.0 µ\" gold over phosphor bronze contacts handle signal duty at 6 A per circuit, with the 125 V rating covering typical industrial control and data interface levels. ## Board locks and ground strap — why they matter on a right-angle D-sub Right-angle D-subs take a lot of mechanical abuse during cable mating and unmating — the lever action of the screw locks tries to peel the connector off the board. The 5747844-4 carries board locks that anchor into the PCB, spreading the shear load across the plated-through holes so the solder joints don't fatigue. The ground strap bleeds shield current from the steel shell directly to the board ground plane, which keeps the enclosure's EMI seal intact without relying on the signal pins for the return path. ## What crosses into the harness you've already got The 5747844-4 mates with any standard DE-9 male plug — the same shell layout as decades of RS-232 and VGA ports. The 4-40 threaded flange is the common locking interface, so the existing screw-lock hardware on your cable assembly will engage. If you're comparing against the 3-1393480-8, that variant ships in a Box rather than a Tray but is otherwise the same AMPLIMITE HD-20 9-position right-angle receptacle — same board locks, same ground strap, same 30 µ\" gold plating. The 8-1437045-3 comes in Bulk packaging. All three are functionally interchangeable for the BOM line; the packaging difference matters for pick-and-place feeder setup.","metaTitle":"TE Connectivity 5747844-4 AMPLIMITE HD-20 D-Sub","metaDescription":"TE Connectivity 5747844-4 AMPLIMITE HD-20 D-Sub receptacle, 9 positions, right-angle solder, 30 µ\" gold, board locks, 6 A, 125 V.
