It terminates 18 AWG wire via a solder cup — a hand-solder joint that lets you replace or extend individual wires without a crimp tool.
Termination and Wiring Fit
Solder-cup termination means the stripped 18 AWG conductor is tinned and inserted into the cup, then soldered with a iron or wave. The stamped body accepts the wire without a ferrule; the cup depth is sized to hold the full stripped length. This contact mates with any AMPLIMITE HDP-20 receptacle socket (order the matching 66569 series socket) inside a standard D-sub shell — the pin and socket pair carry signal or low-current power up to the rated current of the connector assembly.
