2.54mm Pitch Bottom Entry Type Connector
MDF7 Series
sFeatures
1. Board to Board Size Freely Settable
The board to board size can be set at infinite stages, according to the
header pin through type structure and the diverse header variation.
The board to board size can be set at infinite stages.
Board to Board size Freely settable
2. Integrity of Parts Mounted Surface
The parts mounted surface on two boards aren't face each other, and can
be oriented in the same direction.
3. Wide Variation
Single-row product, double-row product, tin plated and gold plated
products are lined up. In addition, the header to correspond to the board
to board size are prepared. Concerning board to board size, other
products can be provided, in addition to products in this catalog. Please
contact HRS company as required.
sApplications
Internal connection of telephone sets and OA/FA equipment, connection
between IPM, IGBT and the board.
