High-Density Signal D-Sub with EMI Shielding
The TE Connectivity AMPLIMITE.050 III 5749069-5 is a 50-position D-sub receptacle built for dense signal interconnects where board space is tight. The 0.050-inch pitch and 0.100-inch row spacing pack 50 contacts into a shell that would normally carry half that count in a standard-density D-sub — useful when you need to route a wide parallel bus or a bank of I/O through a single connector footprint. The steel shell with nickel plating and the shielded construction mean this connector handles EMI containment at the panel or board edge — the shield ties to chassis ground through the flange mounting holes (2-56 threaded inserts) and the latchblocks. Rated 30V and 1A per contact, it is strictly a signal interconnect; the fine pitch and thin contacts won't carry power. Gold-plated phosphor bronze contacts resist corrosion through repeated mating cycles, and the UL94 V-0 thermoplastic housing suits equipment inside enclosures requiring flame-rated components.
50-Position Fit and the 5749069-4 Difference
The 50-position count is the primary fit check — this receptacle mates with any AMPLIMITE.050 III plug of the same shell size. The sibling 5749069-4 carries the same 0.050-inch pitch and 2-row layout but with a different flange feature (latchblocks without the 2-56 threaded inserts). If your panel mount relies on screw-lock retention through the flange, the 5749069-5 with Housing/Shell (2-56); Latchblocks, Rails is the one that gives you both the threaded hole and the latchblock alignment.
