It uses the fine-pitch 0.050-inch contact spacing with 0.100-inch row-to-row layout — a denser footprint than standard D-subs, so the board layout is specific to this series. The steel shell with nickel plating provides EMI shielding, and the housing/shell flange includes 2-56 threaded inserts plus latchblocks for secure mating with the corresponding plug. ## Key Ratings and the So-What for Your Fit The 50 circuits at 0.050-inch pitch mean the current per contact is thermally limited by the dense contact array; don't plan to push the full 1A on every pin simultaneously without checking the derating curve. The gold-plated phosphor bronze contacts handle repeated mating cycles well for a signal connector. Mates with the matching AMPLIMITE.050 III D-sub plug (male pin) — the 2-56 threaded inserts and latchblocks on the shell provide mechanical retention. Termination is through-hole solder to the PCB; the 0.050-inch pitch requires a PCB footprint with tight tolerances. The shielded shell needs a ground connection on the board to be effective — plan a ground plane tie to the shell solder tabs.","metaTitle":"TE AMPLIMITE .050 III 5749721-5, 50-Pos D-Sub Receptacle","metaDescription":"TE Connectivity AMPLIMITE .050 III D-sub receptacle, 50 positions, 0.050-inch pitch, 1A signal contacts, shielded steel shell.
