AXK724147G is a narrow-pitch board-to-board connector featuring a 0.4 mm pitch and Tough Contact construction designed for high-reliability interconnections. The connector supports mated heights of 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, and 3.5 mm, with soldering terminals and a socket configuration of 5.1 mm and header of 3.96 mm. It incorporates impact dispersion keys inside the body to disperse shocks when dropped, ensuring high shock resistance by distributing impact over four mating locations where socket indentations and header protrusions meet. The product is RoHS compliant and utilizes Tough Contact construction for strong resistance to adverse environments and high contact reliability. This connector is ideal for board-to-board and board-to-FPC applications requiring robust performance in demanding industrial and electronic device environments.
