AXK840145WG is a narrow-pitch board-to-board connector designed for compact electronic applications requiring reliable interconnection. It features a 0.4 mm pitch with 40 pins and a 1.5 mm mated height, utilizing Panasonic's "Tough Contact" construction for high contact reliability and strong resistance to adverse environments. The connector incorporates impact dispersion keys inside the body to disperse shocks when dropped, ensuring a high level of shock resistance by distributing impact over four mating locations. This design makes it suitable for applications in portable devices, industrial equipment, and consumer electronics where space constraints and durability are critical requirements.
