The stamped construction keeps per-unit cost down compared to a machined pin, while the brass base material gives good spring properties in the crimp barrel.
What housing does it mate with?
This pin is the male half of the Multimate III+ connector system. It mates into the corresponding socket contact and housing — typically the CPF (Crimp Pin and Socket) or similar TE circular and rectangular housings that accept the Multimate III+ contact family. No solder, no heat — just a clean mechanical and electrical joint that you can replace in the field if a pin gets damaged.
Gold plating and what it means for the job
For a harness that gets disconnected and reconnected during maintenance or rework, that gold thickness buys you reliable contact resistance over the long haul. Tin-plated contacts would be cheaper but would wear through faster under the same cycle count. If your application lives in a corrosive environment or sees frequent field swaps, this is the right plating grade.
