The 4.20mm pitch (0.165") gives each circuit enough spacing to carry moderate current without excessive creepage concerns — typical VAL-U-LOK contacts are rated in the 5-9 A range depending on wire gauge and ambient temperature. The dual-row layout with 0.165" row spacing keeps the overall width manageable for multi-circuit harnesses. The crimp termination allows field-serviceable harness assembly without soldering, and the housing accepts the secondary terminal position assurance (TPA) retainer for added contact retention in high-vibration installations.
How It Compares to a Same-Series Sibling
Against the 6-position single-row VAL-U-LOK variant 1379217-6 (which carries a 3+2 power contact arrangement), the 1586765-8 gives you a straight 8-position dual-row layout — no mixed-power positions.
