The 2-position count means this is a compact power or signal interconnect for a single circuit pair, not a multi-wire harness. ## Glow wire compliant — safety for lighting and appliances This header carries a glow wire compliance rating, which means the housing material meets the IEC 60695-2-11 glow wire test at the specified temperature. For lighting and industrial equipment inside an enclosure, that compliance is often a mandatory safety requirement — the connector will not sustain a flame if the contact overheats under fault. ## Tin-plated contacts — 80 µinch on the mating face Both the mating area and the solder post are plated with 80.0 µinch (2.03 µm) of tin over the copper alloy base. The kinked solder post (3.40 mm length) provides a positive stop during through-hole insertion and increases pull-out force after soldering.","metaTitle":"1744439-2 TE Connectivity 2-Pos 2.5mm Header Glow Wire","metaDescription":"1744439-2 TE Connectivity AMP Economy Power 2.5 header, 2 positions, 2.50mm pitch, 4.2A, 250VAC, glow wire compliant, shrouded, locking ramp.
