37-Position Right-Angle D-Sub for Board-Edge Signal I/O
It carries 37 female sockets in two rows, rated 6A per contact at 125V — typical signal-level current for parallel-port, serial, or industrial I/O breakouts where the pin density at the board edge governs the real load, not the contact itself. The shell is steel with tin plating, shell size 4 (DC, C layout), with a 4-40 threaded flange for screw-lock mating to the matching plug.
Board Locks and Gold Plating for Field-Duty Cycles
Board locks anchor the 37-position body to the PCB during wave soldering and resist shear force from the cable bundle tugging on the mated pair — worth having if the harness runs near a cabinet hinge or a panel that gets opened regularly.
