It mates with a crimp-style receptacle housing to make a locked wire-to-board connection. ## Pitch, position count, and what mates with it All 11 positions are loaded with tin-plated copper alloy tabs. RoHS3 compliant and supplied in bulk packaging — no reel or tape for automated placement, but that's expected for a through-hole header.","metaTitle":"1-1971818-1 TE Connectivity 11-Pos 2.5mm Header","metaDescription":"1-1971818-1 TE Connectivity AMP Connectors 11-position 2.5mm pitch shrouded header, through-hole, locking ramp, UL94 V-0.
