It is designed for through-hole solder termination to a PCB, with gold-plated brass signal contacts rated at 6A per circuit and 125V. The black UL94 V-0 thermoplastic housing carries grounding indents on the shell and a mating-side female screwlock (4-40) on the flange, giving this plug the shield continuity and mechanical retention needed for a cable-to-board or panel-mount interconnect that sees field service. ## 125V / 6A Rating and Operating Range Rated 6A per contact at 125V, this plug carries the standard signal-level current for a DE-9 layout — the 6A figure is per-circuit, not total, so a fully populated 9-position connector can handle up to 54A summed across all circuits, though the practical limit is set by the derating curve and the bundled cable temperature. ## Gold Contacts and Grounding Indents Gold plating on the brass contacts gives this plug the mating cycle life for field-serviceable connections — a tin-plated contact would fret after a few dozen mates, but the gold surface handles repeated insertions without oxidation. The 4-40 female screwlocks on the mating side secure the pair against vibration and cable strain, common in rack-mount and panel-mount installations. Mates with any standard DE-9 (shell size 1) D-sub receptacle with male screwlocks — the 4-40 female thread on the flange accepts the jack-screws from the receptacle side. Termination is through-hole solder to a PCB; the 2-row 0.108-inch (2.74 mm) row spacing and 0.090-inch (2.29 mm) contact spacing are the standard DE-9 footprint. The plug accepts 20-28 AWG wire if used with a solder-cup variant, but this specific order code is a PCB-mount solder-tail version.","metaTitle":"TE 1-747871-4 AMPLIMITE HD-20 D-Sub Plug, 9 Pos, 6A","metaDescription":"TE Connectivity 1-747871-4 AMPLIMITE HD-20 D-Sub plug, 9-position male pins, 6A/125V, gold contacts, UL94 V-0.
