Product details

Stamped Socket Contact for Multimate III+ Harnesses

This is the socket half — it mates into the corresponding Multimate III+ pin contact inside a connector housing, common in power and signal circuits for industrial and automotive harness assemblies.

Wire Range and Termination — What the 20-24 AWG Rating Means

The 20-24 AWG wire range is the primary fit parameter for this contact. The stamped construction keeps the contact cost low for high-volume harness production.

Plating Grade — Tin-Lead at 50.0 µin

Tin-lead is a traditional choice for power contacts where the mating force is higher and the plating needs to resist galling.
