A249
DF18 Series
●0.4mm Contact Pitch, 1.5mm above the board, Board-to-Board / Board-to-FPC Connectors
■Plugs (with metal hold-down terminals)
BPCB mounting pattern
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 (**)
