Harwin’s Gecko (G125 series) connectors provide a low profile, dual row interconnect solution, ideally suited for stacking and cable mating in areas where PCB real estate is at a premium.
With space and weight a consideration for many high-reliability applications, Gecko delivers a pin spacing of 1.25mm, up to 50 contacts per connector. This design means that G125 connectors achieve a 35% space saving over other high-performance connectors such as Micro-D.
