The shrouded 4-wall housing prevents misalignment during mating. Available in tube packaging. The base product number 042820 covers the series; the full 0428204234 suffix specifies the 4-position, right-angle, silver-plated variant.","metaTitle":"Molex 0428204234 Mini-Fit Sr Header, 4-Position","metaDescription":"Molex Mini-Fit Sr 42820 header, 4 circuits, 10.00mm pitch, silver-plated blade contacts, locking ramp, board lock.
