0.4mm Contact Pitch, 1.5mm above the board, Board-to-Board / Board-to-FPC Connectors DF18 Series Low profile Board-to-board distance of 1.5 mm Features High Contact Reliability --- Effective connection wipe of 0.4 mm 1. Allows higher mounting density of board components Extremely small board mounting pattern and low above-the- board profile makes the connector suitable for small device applications. 2. High Contact Reliability Despite its small size and low profile the contacts have large deflection distance, guaranteeing reliable electrical performance. 3. Good Mating Characteristics Large lead-in distance of 0.33 mm in horizontal directions and tactile click confirms fully mated condition of connectors. 4. Optional Additional Board Retention For applications requiring extra-strong hold of connectors to the board connectors can be ordered with optional metal hold- down. 5. Automatic Board Placement Self-alignment distance: 0.33 mm Connectors have large flat width (Plug: 1.4 mm, Receptacle: 1.44mm) to accommodate pick-up with automatic placement machines. Applications Digital video cameras, Digital still cameras, cellular phones, miniature displays, cameras portable equipment and other applications requiring small reliable board-to-board and FPC- to-Board connections.
