14-Position, Single-Row Header – What the Pitch and Lock Mean for the Build
The 1-640456-4: With all 14 positions loaded, the BOM line is straightforward: no unpopulated pins to track.
Mating, Termination, and Series Fit
The through-hole solder termination suits wave-solder assembly; the 0.140" (3.56 mm) post length provides clearance for standard PCB thickness. The single-row, 14-position layout is common for cable-to-board interconnects in control panels, power supplies, and general-purpose equipment where a compact, keyed connection is needed.
ROHS3 compliant. The base product number 640456 covers the family; this specific variant is the 14-position, tin-plated, friction-lock version.
