In a panel or enclosure where the harness gets tugged, those locks keep the solder joints from cracking. ## Locking Ramp and Shroud — Vibration-Ready Mate In an industrial cabinet with fans or a telecom rack with cooling blowers, that ramp keeps the pair mated — a half-turn loose is a dropout, but this isn't threaded; it's a positive lock that won't back off. No keying here, but the shroud alone reduces mis-mate risk on a production line. ## Tin Plating — Cost-Effective for Moderate Duty Tin is the workhorse for connectors that mate a few dozen times over their life — think a PSU harness that connects once at build and stays. For a field-service application cycled quarterly, you'd want gold; here, tin keeps the unit cost down.","metaTitle":"Molex 0039306247 Mini-Fit Jr 5566 Header 24 Pos 4.2mm","metaDescription":"Molex 0039306247 Mini-Fit Jr 5566 vertical header, 24 circuits, 4.20mm pitch, through hole, board lock, tin plating.
