DF57 1.2mm Pitch Swing Lock W2B Connectors

Hirose DF57 1.2mm Pitch Swing Lock Wire to Board Connectors feature a low profile and a unique swing-lock structure to provide highly reliable connections. These connectors feature a stacking height of 1.44mm for an effective mating height of 0.42mm, swing lock with both positive and friction locks for cable pull-force resistance, high-contact lance strength, and integral molding to prevent solder wicking. These wire-to-board connectors have a rated voltage of 50V_AC/DC and a rated current of 0.5A or 2.5A depending on the number of contacts. Hirose DF57 1.2mm Pitch W2B connectors are ideal for LED lighting, LCD TVs, LED modules, and other applications with space constraints.
