The TE Connectivity 748612-1 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, terminated through-hole with solder tails. The 25 positions match the standard DB25 layout, so this part is a direct fit for any application expecting a DB25 female connector — serial ports, industrial I/O panels, or data-acquisition interfaces.
The flange carries female screwlocks (4-40) on the mating side, which accept the male jackscrews from the matching DB25 plug to secure the mated pair. The board lock feature is a metal barb that presses into the board and holds the connector in place during the solder wave — it also adds mechanical retention against the pull from the mating cable.
Rated 6A per contact at 125V — the current per pin is typical for signal-level D-sub applications; it handles digital I/O, low-power analog signals, and control lines, but it is not a power connector for driving motors or heaters. The 125V voltage rating covers most industrial control voltages (24V, 48V, 120V) with margin.
