What the 9-Position DE-9 Shell Tells You About the Fit
The TE Connectivity AMPLIMITE HD-20 5208006-1 is a standard-density D-sub plug in the DE-9 shell size — the footprint that matches the classic DB-9 connector found on serial ports, instrumentation interfaces, and industrial control links. The vertical through-hole solder termination keeps the connector standing upright on the board, which is the typical orientation for panel-mount or cable-entry applications where the plug is secured by the mating receptacle's hardware. The unthreaded housing/shell flange is the key detail for the panel builder: this plug accepts standard D-sub slide-locks or screwlocks, but it does not have a threaded backshell interface. That means the cable-side strain relief comes from the mating receptacle's hardware or a separate backshell kit — not from the plug itself.
6A per Contact — Signal Duty With Headroom
Rated 6A per contact at 125V. The gold flash plating on brass contacts provides corrosion resistance for moderate mating cycles.
Mates with any standard shell size 1 D-sub receptacle — a female D-sub with 9 positions in the same shell layout. The unthreaded flange means the plug relies on the receptacle's hardware for retention. Termination is through-hole solder.
