37-Position Right-Angle D-Sub with Ground Strap
The TE Connectivity 5745784-4 is a 37-position D-Sub receptacle from the AMPLIMITE HD-20 series, terminated through-hole with right-angle solder tails for board-edge mounting.
What the 6A and 125V Ratings Mean for Fit
For mixed-signal boards where a few contacts carry higher current, derate per the TE derating curve. The 125V rating is the working voltage between adjacent contacts; for applications above that, consider a higher-voltage D-sub layout.
Ground Strap and Flange Feature
The 5745784-4 includes a ground strap as a standard feature — a metal tab that connects the shell to the PCB ground plane, reducing radiated emissions. The flange uses a housing/shell (4-40) thread pattern, accepting standard D-sub jack-screws for secure mating and panel mounting. The backset spacing of 0.318" (8.08mm) sets the distance from the mounting flange to the rear of the connector body, which affects clearance behind the panel.
