Brass base material keeps the contact ductile enough for a reliable crimp with standard tooling.
Rated for 14-18 AWG stranded wire, the 66359-4 accepts the common power and signal wire sizes you'd find in a panel or junction box. The stamped construction means the crimp barrel is formed from sheet stock — it crimps consistently with a standard open-barrel tool, and the brass material doesn't work-harden during crimping the way a harder alloy might. If you're re-pinning an existing Multimate III+ housing on site, this contact drops into the cavity and locks with the standard retention tang.
Gold Plating and Field Duty
That thickness supports multiple insertion cycles into the mating receptacle without exposing the brass base to oxidation, which is what you need when a connector gets unmated for troubleshooting or maintenance. In a dry-signal circuit the gold also keeps contact resistance stable below the milliohm range where tin oxides would start to drift.
