The 1.25FJ connector is a 1.25mm pitch

board-to-board connector. Its plug

consists of a unique flexible hinge that

absorbs circuit board misalignment.

Board-to-board connection requires less

labor and is more reliable because the

connection can be made without the use

of harnesses after the printed circuit

boards are installed in their enclosures.
