4.20mm pitch, 4 positions, right-angle — the power header for tight board-to-wire runs
The 1586041-4 is a 4-circuit, 2-row right-angle header from the TE VAL-U-LOK series, with a 4.20mm pitch and 9A per circuit rating at 600VAC. The 4-wall shroud and locking ramp provide positive retention against cable pull — the ramp clicks audibly when the mating receptacle is fully seated, which matters in applications where vibration or service access could otherwise work the connection loose.
Tin is not recommended for frequent unmating or corrosive environments — gold-plated siblings in the VAL-U-LOK family (e.g., 4-1775099-7) exist for higher-cycle or harsher-duty lines. If your BOM calls for gold, the 4-1775099-7 is a direct-form-fit cross-shop candidate — same pitch, same 4 positions, same right-angle through-hole footprint.
