Board-in Connectors

Molex Board-in Connectors include both vertical and right-angle connectors. These connectors are available in 1.25mm, 2mm, 2.5mm, and 4mm various pitch sizes, mating configurations, and circuit sizes. Molex board-in connectors provide space savings and improved cost-effectiveness compared to the two-piece connection system. These connectors offer a more reliable solder fillet when compared to uneven and labor-intensive hand soldering and strain relief after soldering. The board-in connectors ensure a secure terminal retention force, which protects the terminal and functions as a wire alignment and retention device. Typical applications include patient monitoring, infotainment, downlights, power tools, refrigerator, and factory machines.
