Through-hole shrouded header with locking ramp
The 0039293066 is the 6-circuit member of Molex's Mini-Fit Jr 5566 header line, a dual-row board-to-cable/wire connector with a 0.165" (4.20 mm) pitch. The shrouded 4-wall housing with locking ramp provides polarization and positive retention during mating. Tin-plated brass contacts are rated for through-hole solder termination.
Selection notes for the Mini-Fit Jr 5566 series
The 0.165" (4.20 mm) pitch and dual-row layout define the board footprint across the series. The 6-circuit 0039293066 is the smallest position count in the 5566 header family; larger siblings (e.g. 8-, 10-, 12-circuit) share the same pitch, row spacing, and contact plating, so the footprint scales with position count. The locking ramp and 4-wall shrouding reduce the risk of mis-mating in high-vibration environments. The UL94 V-2 polyamide housing meets the flammability rating required for most industrial and telecom enclosures.
