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.","metaTitle":"TE 1-66331-4 Multimate III+ Socket Contact, Tin, 20-24 AWG","metaDescription":"TE Connectivity 1-66331-4 stamped socket contact for Multimate III+ series.
