The flange feature gives you two options for retention: a standard 2-56 threaded screw hole for a screw-lock install (vibration-resistant, good for panel-mount cables), or latchblocks for a quick push-to-lock mate with a matching plug. The latchblocks snap into place on the shell and engage the plug's latch ears — no tools needed for mating, but the screw option is better if the assembly sees shock or frequent disconnect. ## Signal Duty Only — Don't Push the Current The 0.050-inch pitch limits creepage distance, and the 30 V rating confirms it's not for power or bus distribution. If your circuit draws more than 1 A per line, you need a different connector family.","metaTitle":"TE Connectivity 5749721-7","metaDescription":"TE 5749721-7 D-sub receptacle, 68 positions, 0.050-inch pitch, shielded shell, gold contacts, 1 A, 30 V.
