50-Position Shielded D-Sub for Dense Signal I/O
The TE Connectivity 5749070-5 is a 50-position, 2-row D-Sub receptacle from the AMPLIMITE.050 III series, designed for high-density signal interconnect in EMI-sensitive applications. The 0.050-inch contact pitch with 0.100-inch row spacing packs 50 signal contacts into a shell layout that fits a standard D-Sub footprint, saving board edge real estate compared to standard-density 0.108-inch pitch D-Subs. The steel shell with nickel plating and the Shielded feature provide a continuous ground path around the contact array, attenuating coupled noise on the signal lines.
1 A Signal-Level Current and 30 V Rating
The 1 A limit reflects the thermal capacity of the dense 0.050-inch pitch contact array; pushing beyond that risks temperature rise above the UL94 V-0 thermoplastic housing's safe operating envelope. For a 50-position cable assembly carrying 1 A on every contact, the total harness current sums to 50 A, but the per-contact rating is the binding constraint for any single circuit.
Shielded Shell with 4-40 Flange Hardware
The Flange Feature specifies Housing/Shell (4-40) — the receptacle includes threaded 4-40 inserts in the shell flanges for mating with the corresponding plug's jackscrews. The Black thermoplastic housing carries UL94 V-0 flammability classification.
