High Contact Reliability --- Effective connection wipe of 0.4 mm
Features
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.
Male contact
Plug
3. Good Mating Characteristics
Large lead-in distance of 0.33 mm in horizontal directions and
tactile “click” confirms fully mated condition of connectors.
Receptacle
Female contact
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
Connectors have large flat width (Plug: 1.4 mm, Receptacle:
1.44mm) to accommodate pick-up with automatic placement
machines.
Self-alignment distance: 0.33 mm
Self alignment amount : 0.33mm
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.

Added hold-down contacts
Note 1: The terminals located at each of the 4 corners provide additional
hold to the board’s mounting surface and are not part of electrical
connection.
When counting the terminal leads the number of actual electrical circuits is
lower by 4. Example: Connector with 24 terminal leads will have 20 actual
electrical connections when mated with corresponding part.
Note 2: Please note that mounting of parts within the area of the broken
lines will prevent the connector from mating.
D: When the corresponding connector is DF18B- DS-0.4V (
)
E: When the corresponding connector is DF18C- DS-0.4V (
)
