DF51K 2mm Pitch Wire-to-Board Connectors

Hirose Electric DF51K 2mm Pitch Wire-to-Board Connectors feature a center-lock design that prevents damage while allowing high-density mounting and easy operation. The locking mechanism delivers a clear tactile click to ensure complete mating, while visually and mechanically polarized features prevent reverse or incorrect mating. Hirose Electric DF51K connectors are available in straight or right-angle options, single or dual row, and with gold or tin plating. Typical applications include medical, office, and amusement equipment, as well as industrial machinery and robots.
