Molex Brad® Mini-Change® Connectors offer highly durable performance with a IP67 protection rating. The moisture-resistant design includes gold over nickel plating to provide a longer-lasting solution. An epoxy coated coupling nut, a feature offered only in the Molex Brad® Mini-Change® product line, provides a minimum of 500 hours of corrosion resistance.
