The 6 A rating is on the higher side for a signal-density D-sub — it gives headroom for daisy-chained power or multiple signal lines sharing a return, but the gold plating (rather than tin) means the contact interface is designed for moderate reconnection duty, not a one-time permanent crimp. ## Board Lock, Ground Strap, and Grounding Indents — What They Do for the Assembly This plug carries three mechanical features that a basic D-sub omits: board lock, ground strap, and grounding indents. ## Why the Right-Angle Orientation and Board Lock Matter for Board Layout The board lock adds mechanical retention during reflow and resists shear force from the cable bundle tugging on the shell. Without the board lock, a right-angle D-sub on a single-board assembly can crack solder joints after repeated mating cycles. ## Positioning Against the Vertical-Mount 747871-2 The 747871-2 is the same 9-position AMPLIMITE HD-20 plug, but in a vertical through-hole orientation (pins straight down) rather than right-angle. It also lacks the board lock and ground strap — it carries only grounding indents on the shell. Both are rated 6 A at 125 V with gold-plated brass pins. ## Mating Half and Shell Hardware The flange feature is housing/shell with 4-40 threaded inserts — the standard jack-screw spacing for shell size 1 (DE, E). The mating receptacle is the 747844-4, a 9-position female socket with the same 0.318\" backset spacing and gold-plated phosphor bronze contacts.","metaTitle":"TE 747840-4 AMPLIMITE HD-20 D-Sub Plug, 9-Pos Right Angle","metaDescription":"TE Connectivity 747840-4 AMPLIMITE HD-20 D-Sub plug, 9 positions, male pins, right-angle through-hole, gold contacts, 6 A, 125 V.
