The 5897 Series are space-saving Board to Board Connectors featuring a fine pitch of 0.35mm, stacking height of 0.8mm (between boards) and a width of 2.3mm. In addition to its narrow pitches and low profile as with the conventional products containing the robust metals, the metal fittings covering both ends prevent breakage of the insulator housing and contacts due to misalignment in their mating. Thus it is a connector that realizes high robustness and smooth guide into mating. Besides the above, metal fittings are also provided inside the receptacle connector to increase the strength of the connector.The metals at both ends of which rated current is 3.0A/metal tab enable to carry a large current.
