The shielded steel shell with tin-nickel plating contains radiated emissions, making this plug a direct fit for parallel I/O links, industrial controller interfaces, and data-acquisition cabling where signal integrity matters inside a metal enclosure. The IDC termination style means the 5749621-2 is designed to be mass-terminated to standard 26-conductor ribbon cable without stripping individual wires — the insulation-displacement contacts pierce the ribbon in one press operation. This saves assembly time on multi-conductor runs but requires the correct tooling (a hand press or arbor press with the appropriate die set). The free-hanging (in-line) mounting suits it for cable-to-panel or cable-to-board applications where the plug floats on the harness, not fixed to a PCB. ## Ratings and Material Choices for Signal Duty Rated 1 A per contact and 30 V, the 5749621-2 is a signal-level interconnect — the 1 A limit reflects the dense 0.050 inch pitch and the IDC contact interface, not a power-contact design. Gold-plated phosphor bronze contacts handle repeated mating cycles without surface oxidation, which matters for field-serviceable cable assemblies that get reconnected during maintenance.","metaTitle":"TE 5749621-2 AMPLIMITE .050 III D-Sub Plug, 26 Pos IDC","metaDescription":"TE Connectivity 5749621-2 AMPLIMITE .050 III D-sub plug, 26-position, shielded, IDC ribbon cable termination.
