9-Position Right-Angle D-Sub Plug for Board-Edge I/O
The TE Connectivity AMPLIMITE HD-20 8-1393480-5 is a 9-position D-Sub plug with male pins, designed for right-angle through-hole soldering to a PCB. This is the standard DB-9 footprint — shell size 1 (DE, E) — used for RS-232 serial ports, industrial control interfaces, and instrumentation I/O where a compact, shielded connector is needed at the board edge.
Mounting and Retention — Board Lock and Right-Angle Orientation
The flange features 4-40 threaded inserts (housing/shell) for mating with the receptacle's jackscrews, providing mechanical security in high-vibration environments. The backset spacing of 0.371" (9.43 mm) sets the distance from the PCB edge to the front of the shell, which matters for enclosure cutout clearance.
