5-position, 5.08 mm pitch, friction-lock header
The 1744037-5 is a single-row, 5-position header from TE's Economy Power series, on a 5.08 mm pitch — a common spacing for power and lighting interconnects where 7.5 A per contact is the rated current at 250 VAC. The shrouded 1-wall design and friction lock keep the mating receptacle seated under vibration, which matters for industrial and lighting applications where the cable is routed through a panel or enclosure.
Through-hole solder termination, tin plating
Termination is through-hole solder — the contact post is 0.146" (3.70 mm) long, tin-plated at 120.0 µin (3.05 µm), matching the mating surface thickness for consistent solder wetting. The insulation is natural polyamide 6/6 rated UL94 V-0, so the header can be used inside equipment enclosures that require a flame-retardant housing.
