16-Position Dual-Row Header at 4.20 mm Pitch
The 1-1586040-6: Rated 9 A per circuit at 600VAC, with tin-plated brass contacts finished at 80.0 µinch on both the mating face and solder post. The tin finish suits moderate mating-cycle applications—typically 50 to 100 cycles—in clean, indoor environments where corrosion is not a concern.
9 A per Circuit at 600VAC — Power Delivery and Derating
The 9 A current rating is per circuit at ambient temperature, with the 4.20 mm pitch providing adequate spacing for heat dissipation between adjacent contacts. At 600VAC, the connector meets typical industrial and lighting power distribution requirements. Compared to the 10-position single-row variant in the same series, this 16-position dual-row header offers a higher circuit count in a compact footprint, with the same 4.20 mm pitch and 9 A rating. The dual-row arrangement reduces board length compared to stacking two single-row headers side by side.
The part is ROHS3 Compliant, meeting current environmental regulations for solder assembly. Sourced through independent distribution channels.
This header mates with the VAL-U-LOK receptacle housing (e.g., 1-1586039-6 or similar 16-position dual-row receptacle) and accepts the matching crimp terminal (such as 1586038-1 for 18-24 AWG wire).
