Stamped pin contact for Multimate III+ housings — 20-24 AWG, tin finish
This is a male pin contact — it mates with the corresponding socket contact inside a Multimate III+ housing. The stamped construction means this is a formed, not machined, contact — suited for high-volume harness production where the current and cycle-life demands fall within tin's envelope.
Tin finish — cycle-life and cost trade-off
The tin contact finish (50.0µin / 1.27µm) on the 1-66103-9 is the key selection differentiator within the Multimate III+ contact family. The thick tin layer here gives better shelf-life corrosion protection than a thin flash, but the mating-cycle ceiling is still governed by tin's tendency to oxidize and increase contact resistance over repeated insertions.
Crimp termination — harness-ready
Crimp termination means this contact is installed with a standard crimp tool — no soldering, no heat shrink. The 20-24 AWG wire range covers common signal and low-power circuit sizes in industrial control and automotive harnesses. The brass base material provides good conductivity and formability for the crimp barrel, and the tin finish on the crimp area ensures a reliable gas-tight connection with the wire strands.
