Product details

Brass base material offers good conductivity and formability for consistent crimp performance.

Tin Plating — What the 50.0µin Means for Your Build

That extra thickness extends the usable cycle count before exposing the brass substrate.

Crimp Termination and Wire Prep

Crimp termination for 20-24 AWG wire — the strip length and crimp die selection follow the TE application tooling for Multimate III+ contacts. The stamped contact geometry produces a consistent barrel crimp when the correct tool is used; hand-crimping with a universal tool is possible but the pull-off force spec is only guaranteed with the series-specific die set. For volume production, the tape-and-reel packaging feeds directly into semi-automatic crimp presses, keeping cycle time per termination under control.
