Features
1. Board-to-board distance can be freely set.
Pass-through construction header pins and many header variations
allow you set the board-to-board steplessly.
2. Arrangement of component sides
Components sides of two boards can be arranged on the same side,
without facing each other.
3. Many variations
Single-row, double-row, tin-plated, and gold-plated models are
available, as are various types of headers to suit board-to-board
distance requirements. For board-to-boards distances not specified
in our catalog, please contact us.
Board-to-board
distance can be
set steplessly.
