The 2.50mm pitch and shrouded 4-wall design keep the mating housing aligned and prevent accidental shorting across adjacent contacts. ## Tin plating and friction lock for production environments Compared to the 3-position sibling 1-2232960-3, this 4-position version adds one circuit while keeping the same 2.5mm pitch and tin plating — the extra position matters when your harness needs that fourth wire.","metaTitle":"1744439-4 TE Connectivity Economy Power 2.5 Header 4 Pos","metaDescription":"1744439-4 TE Connectivity AMP Connectors header, 4 positions, 2.5mm pitch, tin-plated, friction lock, glow wire compliant.
