The shell layout is DE-9 (size 1, E), the standard footprint for RS-232, instrumentation, and industrial control ports.
Wire gauge acceptance is 22-26 AWG. The IDC termination pierces the insulation and makes contact with the conductor in one press operation — consistent termination quality without stripping or crimping. The unthreaded flange on the housing accepts standard D-Sub slide-locks or screw-lock hardware (not included) for panel retention.
Position Count and Sibling Comparison
At 9 positions, this is the smallest shell size in the AMPLIMITE HDE-20 IDC receptacle family. The same series also offers 15 positions (745205-7) and 25 positions (745209-7), all sharing the same 22-26 AWG wire range, gold plating, and free-hanging form factor. Pick the position count that matches your circuit count — the shell size changes, but the termination method and contact finish stay identical.
