The TE Connectivity AMPLIMITE HD-20 5747845-5 is a 15-position D-sub receptacle with female sockets, arranged in two rows. The connector is part of the standard-density DA-15 shell size layout (2, DA, A), meaning it mates with the matching DA-15 male plug and fits the standard 15-position D-sub panel cutout. Typical applications include serial ports, industrial control interfaces, data communication equipment, and any board-edge I/O where a reliable, shielded signal connection is needed.
Key Features for Board Fit and Assembly
The flange features female screwlocks (4-40) on the mating side, so you need a male plug with matching 4-40 threaded inserts or jackscrews for a vibration-resistant mate.
The gold flash contact finish (gold over phosphor bronze) provides corrosion resistance for environments with moderate humidity or occasional mating cycles; for applications requiring thousands of mates, a thicker gold plating would be specified.
Termination and Assembly Note
Termination is solder — the contacts are pre-loaded in the right-angle PCB mount body, so you align the through-hole pins to the board and wave-solder or hand-solder them. The steel shell with tin plating provides basic RFI/EMI shielding when mated; the ground strap should be soldered to a ground pad on the PCB for best shield continuity.
