It uses the standard shell layout 1 (DE, E). Rated 3A per contact at 250V, which is typical for signal-level D-Sub duty — driving RS-422 lines, low-power sensor loops, or control signals where the current per pin stays well under the limit. Through-hole solder termination with a board-side 4-40 threaded flange — the flange lets you bolt the receptacle to a panel or bracket for strain relief, not just rely on the solder joints. The board lock feature adds mechanical retention during reflow or wave solder, and the steel tin-plated shell provides EMI shielding when mated with a grounded plug.","metaTitle":"L77SDEH09SOL2RM5C309 D-Sub Receptacle, 9 Pos, 3A, Gold","metaDescription":"Amphenol L77SDEH09SOL2RM5C309 D-Sub receptacle, 9 positions, 3A, 250V, 30.0µin gold, board lock, through-hole solder.
