Features
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.
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.
